Casting glass molds can be difficult process if you are new to the glass working hobby, but it doesn’t have to be overwhelming. One of the most important decisions to make when making glass casting molds is to choose which technique to use. Here are some of the more common techniques that you can use to do glass casting molds so you can choose the one that’s right for you.

Frit casting is one of the more popular ways of casting glass molds and it involves putting pieces of frit glass into a mold that has been kiln washed. You can then heat up the piece until the glass fills the entire mold. This can take some time, however, as it may take several firing processes before the project is completed.

Hot casting is another way to create glass casting molds. With this process, you pour the already molten glass into an existing mold. Because of the experience and technical know-how needed to accomplish this process safely, it is recommended that beginners and novices do not attempt hot casting until they have a lot of experience working with molten glass. This process uses a furnace and other unique tools used with glass fusing along with safety precautions that you may  not think of if you are not experienced with glass working.

Sand casting is another form of glass casting molds. This is one of the older techniques and involves molds made of silica sand that has a binding material mixed in with clean sand along with a small amount of bentonite. The main drawback with using the sand casting method for molds, however, is that the mold is only usable one time and then it cannot be used ever again.

As with any technique for glass casting molds, it is important to take the proper safety precautions. Make sure your kiln is located away from the work areas to avoid people bumping into them or getting burned by the heat that is often emitted from them. You should also make sure the surrounding area is free of clutter. Always have a proper ventilation system for the kiln’s heat and make sure you wear safety gear when working around a kiln, such as kiln gloves, dark safety glasses specifically  made for working with kilns and other attire. A few minutes of precaution can prevent injury and other potential damages that a kiln can cause if not used properly.
