What is a Stained Glass?
Stained glass is a colored glass that is commonly used for decorative window designs and other art glass. This is commonly seen in church windows, art galleries, and science studios. There are a lot of useful things you can do for this material, but knowing how to grind stained glass, is still a difficult task and an important thing to be learned.
Grinding small pieces of stained glass can be quite difficult and challenging, especially if you are not skilled enough to grind these kinds of materials. This will certainly require precision and accuracy since you have to achieve that good fit or detailed design. Since you are dealing with a small piece of glass, the tendency of putting your finger in the way of the grinder will be a bit of a problem and you might end up losing them. So, to put an end to this dilemma, here are some valuable tips from the experts on how to grind stained glass.
Tips on How to Grind Stained Glass
There are various affordable and innovative tools, methods, and machines that will guide you on how to grind your stained glass efficiently. One of the common tools that are being used nowadays in grinding stained glass, is the use of a glass grinder. Here’s a short description of a stained glass grinder and how it is being used in grinding operations.
Stained Glass Grinder
This glass grinder can be the most useful tool in your workspace since it guarantees the perfect shape of a piece of glass. Use a glass grinder to smoothen any rough spots or edges on your glass piece. Glass grinder is an abrasive wheel covered with a fine diamond coating that is attached to an electric motor. When the power is turned on, the motor will start spinning the wheel and you can now proceed to grind.
- Before you can grind the glass piece, make sure that the wheel is wet. This will definitely reduce friction between the wheel and your glass piece. This is also a great way of preventing tiny glass particles from kicking off. In some cases, machinists use a compartment of water with a sponge attached to it so it can soak up the water and keep the wheel’s humidity throughout the grinding process. Some also use a cap-full grinder coolant which is a great help in prolonging the life of the wheel and maintaining optimum speed.
- The next thing to do, before grinding your main glass piece into the wheel, would be best to cut a piece of paper with your desired shape and glue it to the glass using rubber cement. This will serve as your guide to make sure that you don’t grind off more than you need to.
- Now let’s proceed to the grinding process. The first thing you have to do is to place the glass piece on top of the grinder’s surface. Slowly press the edge of the glass against the spinning wheel. Don’t put too much pressure while grinding. You just have to make sure that edges are smoothened evenly and those parts with sharp corners should not be blunted off.
- Be careful not to strip the paper guide which might happen when you are grinding too much. When that happens, chances of getting an accurate glass fit are low and you end up starting from the beginning because the pieces won’t fit when assembled.
- If you are done with the grinding process, and there are no visible rough spaces on the edges, then take a wet sponge and rinse them off with a soap or detergent. This will remove the glued paper guide so you can have a smooth-edged glass piece ready for the next process.
Stained Glass Grinder Cookie
This glass grinder cookie is a small grinding tool that looks a bit like a flying saucer which is an amazing tool for holding small bits of glass in place when grinding. This tool gives you enough control over the grinding process, which lessen the chances of breakage or damage to the glass piece. Aside from that, you can easily hold the tool since you don’t need to grip it tightly.
This glass grinder cookie is recommendable for grinding shapes that taper off into thin tips. With this, you don’t need to hold the glass throughout the process. You can ensure safety on your nails and fingertips. Plus, you won’t get cramps during the grinding operation.
Grinding Guidelines: Things You Have to Remember when Grinding Stained Glass
For those who are just starting with the grinding application, you might find it difficult in the first part. But soon enough, with enough practice and valuable experience, you can eventually get the hang of it. To guide you throughout the whole grinding process, here are some expert tips you need to know before doing the job. These useful tips will definitely benefit your glass grinding experience.
The first thing we have to prepare, before doing any dangerous work is to ensure the safety of all persons involved in the process and in the surrounding area. Here are some safety practices you can do before the grinding process:
- A stained glass grinder is an electric-powered machine which means you have to be aware of any electrical hazards and its safety protocols. Make sure your working space is clean and free from hazardous materials. Use protective gear like safety goggles or glasses to protect your eyes from possible glass dust or particles.
- You can also use safety face shields to prevent airborne glass particles from getting into your face.
- To make sure your fingers are safe, you can put safety bandages, tapes, or finger guards available on the market. Avoid picking up pieces of glass on the inner edge since there are bits of sharp edges on the ground area and you might scrape your fingertips.
Practice Grinding or Do Dry Runs
To avoid project waste and start another grinding work when the result is a failure, try to practice grinding on a small leftover piece or an old piece of glass before performing the grinding operation on your main glass material. Here’s why you should perform practices and dry runs before the actual process.
- Doing a couple of grinding operations on a leftover glass piece will give you the feel of how the grinder works on the material and how should you grind the glass piece. Always remember that the grit of the grinder should correspond to the type of glass being used.
- Practicing grinding operation on your preferred shape will increase the chances of success rate. Plus, getting a grasp of the texture, form, thickness, quality, and shape of the material is necessary, so you can make some initial adjustments before the actual grinding operation. For instance, you want to practice first on a fragile glass type, then make sure to adjust your grinding process by applying less or more pressure to the main glass material to achieve your desired result.
Many experts in glass grinding share important tips when it comes to the direction of the glass in relation to the grinding bit. For stained glass, the grinding bit is commonly done in a counter-clockwise direction. To achieve a much deeper cut in the glass, it is best to grind the glass piece in the opposite direction by pushing the glass clockwise. If you want some changes in the glass piece, push it in the same direction where the grinder bit is going. Observe closely the changes in your grinding bit. It is also important to know what type of grinding bit is suitable for your material since different types of grinding bits need a specific amount of pressure.
