Acrylic Aquariums Vs Glass Aquariums

Filed under: Pets — Tags: , , — admin @ 9:48 am




Acrylic aquariums are growing ever more popular in today’s aquarium industry. Acrylic aquariums are slowly moving glass out of the spotlight for a variety of reasons. In this article I will be going through and detailing the strengths and weaknesses of glass versus acrylic aquariums. Glass has been around for a while in the industry, and a lot of the old hands will swear by it, it does have its strengths, but also its limitations.

Glass is much more dense than acrylic, which means it also weighs a lot more. Glass aquariums weigh up to 10 times as much as their acrylic counterparts. When purchasing an aquarium, it would be best to go with acrylic.

Acrylic aquariums are much lighter, and will cause much less stress on the stands and structures you will place them on. You can also purchase a larger acrylic aquarium that weighs less than a glass one, so you can bend the rules a little bit on weight restriction for your stand.

Acrylic aquariums may weigh less than glass, but don’t let that fool you. Acrylic is a very strong material, and it takes significant force to break an acrylic aquarium, and anyone who has every owned a glass aquarium can tell you about how even little bumps can cause cracks in the aquarium and cause it to be structurally unstable.

Even though glass is thicker than acrylic, it is much weaker. Acrylic aquariums are very resistant when it comes to bumps, however they are more easily scratched than glass aquariums.

When it comes to customizing the shape of your aquarium, you are pretty limited when it comes to the glass aquarium. Glass is relatively brittle and rigid naturally, and because of this, its shapes and styles are very limited. Acrylic aquariums on the other hand, can be molded to fit any shape and design that you could wish for.

Acrylic aquariums can be cast and molded into different shapes that were never though possible when only working with materials such as glass. Acrylic aquariums are also much easier to cut holes into when attaching an overflow system, with glass you need specialized tools and then you run the risk of cracking the whole panel.

The only spots, in my opinion, where glass outshines acrylic is in terms of cost, and scratch resistance. Glass is cheaper than acrylic, as it is more readily available. Glass is also very hard to scratch, and acrylic aquariums can be scratched with less force. Glass will also maintain its clarity throughout time, but acrylic when it gets a lot older can develop a yellowing tint to the acrylic.

Well there you have it folks, a couple points to consider when you are weighing your options between glass and acrylic aquariums. I would personally recommend acrylic, as it is a lot more durable to bumps and impact, also if you are trying to get a custom aquarium, acrylic can be molded to just about any shape.

Stands For Displaying Glass Art

Filed under: Home Improvement — Tags: , , — admin @ 9:11 am




Glass art is the art of the future. Many people are finding the joy in owning one-of-a-kind glass art. If you are lucky enough to own a beautiful piece of glass art, you are probably trying to figure out how to display it. Stands for glass art are a wonderful option. These useful pieces of furniture will display your glass art properly and keep it safe as well.

The first type of stands for glass art is standard display stands. These stands might be specially made for glass art, or other art, or they might just be a piece of standard, non-art-related furniture. You have to decide what kind of stand to purchase based on your room decor. You might choose a specially made stand that matches your art piece. Or perhaps you want a mirrored art stand or a certain shape or color to compliment your glass art. Or you might consider purchasing a stand that is not made especially for art display, but still looks good with your specific glass art piece. Antique stands are a great option in this category.

The second type of stands for glass art is covered stands. These stands have a glass cover to ensure extra care of your glass art piece. When you are purchasing a glass art stand with a protective cover, make sure you do all the proper measurements beforehand. Many companies will allow you to request a specific size of glass case so that you can be sure your glass art piece will fit inside safely and securely.

The final type of stands for glass art is glass cases. These cases are often referred to as “hutches”, “curio cabinets”, or “china cabinets”. These are extremely sturdy and offer the most protection for your glass art. They come in many sizes, often you can fit many different pieces of art inside. They are also available in many different styles. Consider a minimalist streamlined case for your urban loft, or a traditional wood style for your country-decor home.

There are a few more things to consider when it comes to stands for glass art. Make sure when you are shopping for a proper stand that it is sturdy. The last thing you want is a weak base for your fragile, treasured art piece. You should also make sure you clean your stand, case, or cabinet regularly in order to keep your art looking beautiful. Remember that you can also have art stands specially made. This can come in handy if your art is large or oddly shaped.

Solar Panel Glass - Tempered Vs Plate

Filed under: Home Improvement — Tags: , , — admin @ 6:25 pm




When shopping for a solar panel brand, the issues at the forefront of people’s minds are usually topics such as efficiency and wattage. An often overlooked issue is glass - and the type of glass used on a solar panel really does matter.

When you buy a solar panel, it’s a long term investment - it should serve you well for decades. While most manufacturers offer lengthy warranties, some up to 25 years, it’s important to note the manufacturer needs to be around to honour it. There’s still many fly-by-nighters in the solar panel industry, cutting prices by cutting corners on component quality.

While a warranty from a solid company is a great insurance policy, there’s also the inconvenience of needing to make a warranty claim - pulling the panels down, taking them in - it’s all very disruptive and stressful. It’s best to have peace of mind from the outset and you can only have that if every part of the panel is of the highest possible quality.

The dangers of cheap solar panel glass

Cheap glass can cloud over time. Clouded glass greatly reduces solar panel efficiency. Broken glass, aside from being a general safety issue and even if the glass only cracks, can allow water to penetrate and create a fire hazard - water and electricity simply do not mix.

When selecting either a monocrystalline, polycrystalline or amorphous solar panel, be sure to check out the type of glass being used. Look for panels that utilize tempered glass - this should be clearly stated in the panel specifications.

What is tempered glass?

Tempered glass, also known as safety glass or toughened glass, is anything up to six times the strength of normal plate glass. It is created by thermal or chemical means. We’ve witnessed panels using tempered glass flip over onto rock strewn ground with some force without breaking.. This is something we obviously do not recommend trying out, but it goes to show how strong the material is. When tempered glass does break, it shatters into small pieces rather than creating long and razor sharp shards.

Flat plate glass in solar panels

This is most often found in cheaper brands of monocrystalline and polycrystalline panels made by small, relatively unknown companies; however it can also be found in well known brands in amorphous (thin film) solar panels that have a glass plate component.

Most amorphous panels can only use flat plate glass due to the way they are constructed. Amorphous panels are usually created by applying special silicon rich gas called silane at high temperatures directly to the back of a glass plate or to a steel plate. Some manufacturers get around the comparative weakness by using thicker flat plate glass, but this is still not as strong as using white tempered glass.

When buying solar panels, don’t forget that this is an important point to check on - as mentioned, it should be clearly stated on the product specifications as to the type of glass used as it’s an important feature. If it doesn’t, the chances are it’s flat plate glass and should probably be avoided.

Magnifying Glass - A Short History

Filed under: Reference And Education — Tags: , , — admin @ 4:50 pm




The magnifying glass is one of the oldest devices used to improve sight. Historians seem to agree that the Romans were the first to discover glass in the first century AD. The Egyptians had discovered an almost clear crystal, called obsidian that was used to view small objects

The Romans were probably looking through the glass and discovered that the objects looked larger. They experimented with different shapes and found that glass that was thicker at the center and thinner on the outside magnified the object that was being observed. They also discovered that the suns rays could be concentrated sufficiently to start a fire. They called these glasses “burning glasses”. These glasses were similar to the shape of lentils, and so the word “lens” comes from the latin word for lentil. The benefits of these lenses were not appreciated until the 13th century, when scientists used them to study tiny insects. They were then called “flea glasses”.

During the 16th century, the first primitive microscopes were invented using multiple lenses and so a new industry was born. Magnifying glasses continued to be used for low levels of magnification, when compared to the magnification ability of the microscopes. Telescopes were soon invented using lenses that were just arranged differently within a tube..

Modern magnifying glasses are double-convex lenses and they make the objects appear larger. The lens is convex on both sides, ie. thicker in the middle. When viewing objects the light rays are bent towards the center of the lens, making the object look larger than it is to the eye. Each magnifying glass has a focal length, which is the distances from the optical center of the lens to the point where the light rays converge. The focal length of any lens is determined by the radius of the curve on the face of the lens. The mathematics that describe magnification is relatively straight forward and can be found in comprehensive physics textbooks.

Magnifying glasses are now manufactured with many configurations. The basic magnifying glass has the glass attached to a handle, which may be made from almost any stiff material. Many different sizes are available form the small round compact pocket magnifying glasses to the large rectangular full-page magnifiers. Many have built-in lighting systems to allow the user to see objects better.

The magnifying glass would have to be one of the most simplest aids available today for people who want to study small objects, for people who have trouble seeing the text in newspapers and books as well as handy tool to take to the outdoors as a fire starter.

Magnifying glasses of almost any configuration are available from many shops and online.

Antique Glass Hens - Great Glass Collectibles

Filed under: Shopping And Product Reviews — Tags: , , — admin @ 8:33 pm




Sometimes an antique gets its value from rarity and scarceness, while other times an antique may get a lot of its value because it has a collectible quality to it. Glass hens are a great example of this.

Antique glass hens can be both. Not only is the glass valuable and rare, but being in the form of hens, these dishes are often very appealing by sight. These dishes are among my mom’s favorites, as the kitchen has three shelves of antique glass hens from all different colors and sizes.

That is part of what is appealing. Purple, blue, red, orange, pink, white, tangerine, yellow, and green antique glass chickens all sit together on the same shelf. These chickens can also be from a wide variety of companies, from the usually non-collectible, to famous glass companies such as Fenton Glass.

These are attractive not only because you can’t often find designs and craftsmanship like this now, but also because whether antique or not, these decorative glassware pieces can be enjoyed. The extra value that comes from being antique makes some of these glass chickens quite valuable.

This is part of the fun of antiques. It’s not just “old stuff,” the antiques are beautiful, well detailed art. At home we tend to tease Mom about all her glass chickens, but they are wonderful pieces of art that add a brightness to the kitchen that wouldn’t be there otherwise.

Finding antiques that you love is the best reason to get into the hobby. Maybe you will find that you love the beautiful antique glass hens as much as Mom does!

Glass Block Window Sizes For Basements, Bathrooms, and Buildings - 4 Steps For Success

Filed under: Home Improvement — Tags: , , — admin @ 12:02 am




When sizing a glass block window panel you need to throw out the old saying “measure twice and cut once.” With an interior or exterior block window project you need to measure twice and don’t cut at all (this is because you can’t slice through a block and have it retain it’s structural integrity and energy efficiency properties). Although determining the size of the block glass window does require skill and knowledge, it does not take a neurosurgeon to figure this stuff out. In this article you’ll learn the 4 step process to get the correct window size, system, pattern, color and options for your needs and tastes.

Step 1) Where do you want to use the block window? What material is (or will be surrounding) surrounding the window opening?

o Will your glass block window be used in a lower level basement, a 1st floor garage or commercial building, or a 2nd floor bathroom window that is 20 foot to the sill? If you’re putting the window on the lower level you can generally make the window panel larger since you won’t have to be lifting it in the air (most basement windows tend to use anywhere from 8 to 15 blocks in a pre-assembled section - weighing from 50 lbs. to 90 lbs per section). Most second floor bathroom windows tend to use 12 to 24 blocks so you might want to select a thinner block thickness (either 2″ or 3 1/8″) so the panel is lighter and easier to install.

o The surrounding materials the window panel will be set in (also called the head - or top, jambs - or side, or sill - or bottom) are also important. If you’re doing a basement foundation window that will be set inside a masonry wall made of concrete block, sandstone, or poured concrete you may want to size your block window using a mortar joint (to match up with your surrounding masonry materials) vs. a silicone jointing process for the window. For a bathroom window inside of a wood framed opening the silicone vinyl framed glass block window system might be preferred because this window is lighter (usually built with 2″ thick blocks) and easier to set, making an upper level installation safer.

Step 2) Measuring an existing opening or determining the size you’d like to create a new opening

o To replace an existing window you start by measuring the opening first. When measuring an existing masonry opening for block basement windows or upper floor windows you usually want to measure assuming the frame will be removed (this happens about 90% of the time), from side to side, and from the top of the sill to the top of the header plate. The block window will need to be sized smaller than this opening remembering that you can’t cut the glass, or as my Dad used to say fit 10 lbs of you know what into a 5 lb. bag. For upper floor frame openings you usually will measure the area inside of the frame after the window sashes would be removed to size your window.

o Creating a new opening for a block window If you’re creating a new opening for a block window you want to begin with the end in mind. Choose your specific block window system, pattern, design, and/or colors and find out from your glass block window manufacturer what size the window panel will be after it’s manufactured. Then you’ll create your opening usually about

Glass Block Wall Prices - 6 Step to Get the Biggest Bang For Your Buck

Filed under: Home Improvement — Tags: , , — admin @ 8:46 am




Everyone wants the biggest bang for their hard earned money - especially in these tougher economic times. How can you stretch your budget and get the most value in a glass block wall project? This article presents 6 concrete steps you can use to get your block wall completed at an affordable price.

Step 1 - Don’t hire “Cousin Vinnie” - Everyone has a “Cousin Vinnie,” a self proclaimed construction expert who can do it all. For a low, low price he’ll get ‘er done just for you. Don’t get ****** into the lure of a low initial pricing for a block wall specialty project. Check credentials (Angie’s List, National Association of the Remodeling Industry, Better Business Bureau, Consumers Choice Award Winners, and past customers) and ask, “Does my potential contractor have experience specifically with glass block walls?” The design, fabrication, and installation is more complex, detailed, and structurally significant than a glass window project or other glass wall systems.

Step 2 - Curves are cool, but straight is slicker for your budget - Curved glass block wall sections are graceful and interesting to look at. Their drawback - they require a higher skill level and cost about 20 to 40% more per square foot than a straight wall. If you want a stylish look at a cost-effective price design straight walls and consider adding either 45 degree angles or corner blocks for interest (many of these walls can be manufactured in a factory and shipped to you).

Step 3 - Add colors, tints, and designs to your glass block walls up front - If you want a one of a kind look add colored, tinted, or artistically decorated blocks to the wall installation project. Taking block out later to add styled blocks will cost significantly more than installing them in the original installation. Since these blocks come in a wide variety of shapes, colors, and even tints they can be used whether you want a vibrant colored look, or a more muted hint of color.

Step 4 - Consider both foreign and domestically manufactured block for your project -Although block that is manufactured overseas (especially block from China or Indonesia) tend to be less costly than U.S. made blocks don’t necessarily jump to get the foreign made blocks. Check the following before making your selection:

o Is my pattern selection available in American sizes? Does this manufacturer make end block finishing units, corners, angles, colors and tints for my design?

o Glass clarity and consistency. All blocks are not made alike. Is the manufacturer and installer/ distributor you’re considering known for their quality and service? Reputable contractors install only reputable products. Get a good value right from the beginning.

Step 5 - Prefabricate it and then you will save - Block wall panels can be factory assembled and shipped directly to your project site - saving time, money, aggravation, and increasing product quality. These sections can be made in 3″ and 4″ thicknesses and can include a variety of shaped, colored, and tinted glass blocks.

Step 6 - Don’t leave home without them…..the block accessories that is - As is true with most building projects what you don’t see (the structure inside, beneath, and at the top of an installation) is crucial to the long run visible quality of the work. Glass block mortar, spacers, wire reinforcing, anchors and in some cases intermediate wall stiffeners will make or break the wall’s quality over time. Refer back to step 1 (Don’t hire Cousin Vinnie) and find a block specialty designer, contractor, fabricator, and installer to ensure the correct wall accessories are being used.

Now that you’re equipped with these 6 price and cost saving wall ideas you should be ready to start your project.

Stained Glass Kits - 12 Essential Items For Making Leaded Glass Panels

Filed under: Home And Family — Tags: , , — admin @ 4:40 pm




Do you want to learn how to make stained glass but faced with a confusing array of stained glass tools and materials? Here’s the top 12 essentials for a stained glass kit, with buying tips and brief user descriptions to help your stained glass career take off without a hitch. All are available at any good stained glass suppliers.

Cutting

1 Oil-filled cutter. There’s lots of different types of cutter, but make sure you buy one that has a reservoir for oil. This automatically lubricates the tugsten carbide wheel as you make your scoreline, which saves you from constantly having to dip it in oil. Buy an oil-filled pistol grip cutter if you think you might have trouble applying pressure with a pen-shaped cutter.

2 Grozing Pliers. A tool specifically made for stained glass, the grozier is used for breaking difficult cuts and nibbling the edges of glass.

Leading

3 Lead knife. You’ll need to cut those 6ft lengths of lead accurately, so buy a dedicated stained glass lead knife and keep it sharp.

4 All Nova Tool or Fid. Silly names, but it’s actually one of the most useful - and cheap! - tools in your stained glass kit. Use it to open up the lead cames before leading, and to close them down after cementing.

5 Lead Vice. You could trap lead cames in your door before stretching it, but instead, keep your partner happy by investing in a lead vice. It grips one end of the lead whilst you tug on the other with pliers. Hold on tight!

6 Horse Shoe Nails. These have been stolen from blacksmiths - they use them to bang into horses hoofs, we use them for holding in place all those really annoying bits of lead that pop out all over the show when you’re leading up.

Soldering

7 Tallow Candle. These are made of animal fat and are used as a flux for the solder. Rub a bit on to each lead join before you solder. Think roast beef!

8 100W Soldering Iron. Try to get a soldering iron with a thermostat, as it won’t melt you’re carefully cut lead. My students have tried both gas and 200W soldering irons over the years, but the general consensus is that the 100W is the easiest to handle, and powerful enough for any soldering job.

9 Grade C Solder. Made sure you buy solder that’s 60% lead and 40% tin for leaded stained glass work. Try to work in a well ventilated area when soldering - along with everything else related to stained glass, it’s dangerous!

Cementing and Polishing

10 Leaded Light Cement. Strictly speaking this isn’t exactly an essential, as you can make this up a lot cheaper with standard putty, white spirit and black powder paint. But I don’t want to put you off with that hideous messy job right at the beginning - so buy a pot of ready made cement for starters.

11 Whiting. Used for absorbing all the mess made by the cement. Just sprinkle it over your panel and brush it off. Use some muscle.

12 Black Grate Polish. Use a shoe brush to shine your leads to twinkly perfection. Stand back and admire.

I admit it, I cheated. Top marks if you’ve spotted the two vital missing items in this otherwise most comprehensive of stained glass kits - glass and lead! But that’s the fun bit and for you to enjoy - gazing in wonder at all the different types of glass, the amazing array of textures and colours, and imagining the creative possibilities ahead…bliss!

Appreciating Glass Countertops

Filed under: Home And Family — Tags: , , — admin @ 7:42 am




Glass has been used in many applications. Glass bottles are used to store wine, glass jars are used to store pickles and glass slippers are used to round off a fairy tale. Glass is used in windows to let in the light while keeping out the rest of the elements. But is glass is brittle and breaks quite easily. Due to this, its application is limited to delicate matters that can be kept under care. The invention of Perspex allowed glass-like application in the automotive industry. Then there is plastic which can mimic the transparency of glass.

Glass countertops are a thing of beauty. It gives the countertop a kind of depth effect while simultaneously giving the countertop a prestigious look due to the glass’ clear surface. Normally, thick glass is needed to meet the required strength of holding up some weight. Even then, the glass is set onto a solid surface as a complement. This type of countertop design is usually pairing glass with an artistic surface - be it some form of artistic pattern or the natural grains of wood or stone. The glass surface will enhance the countertop further.

To stand on its own, tempered glass would be the way to go. Although not completely break free as many believe, tempered glass is much stronger than normal glass. With this attribute in strength, a glass countertop design is given more options than just resting it on a solid surface. With tempered glass, it is possible to create a floating glass countertop where the glass surface is placed on several resting points on a countertop to give it a floating effect.

One can also create a see through countertop with tempered glass. One way of doing this is by setting the glass onto a countertop that is cut through in the middle. You can then either have no cabinets at the bottom or a cabinet unit where you can look through the countertop and into the first level of drawers.

Another idea is to make an island with only the glass countertop as a little showpiece in the middle of your kitchen. To take this idea a step further, you can even build a whole countertop plus storage space made entirely of glass!
