How To Prepare For Glass Fusing? A Complete Fusing Guide

Glass fusing is a process wherein glass is melted and fused to produce dynamic pieces with texture and mixed media. You need to assemble materials and tools and prepare the kiln shelf. You’ll also need to know how to prepare the glass fusing kiln safely. Before starting glass fusing, you must prepare your studio for safety and use the proper equipment. Here is the ultimate guide for glass fusing.

Kiln wash:

Kiln wash is a powder which is used to clean a kiln. You can buy it from most ceramic supply stores. It is recommended to use a respirator and a mask when handling it. You can also mix it with water to make a liquid before using it. After using it, dispose of the liquid in a garbage bin. If you choose to use the powder form, you should dispose of it outdoors. The dust is hazardous to your lungs.


Annealing is a technique where molten glass is cooled to a specific temperature before it is fused. The exact temperature varies depending on the type of glass and its maximum thickness. Once annealed, the glass can be drilled, shaped, and polished without the risk of shattering.

Glass cutters:

There are several types of glass cutters for glass fusion. The cutters vary in angle and width. Some are ideal for cutting thin glass, while others are more suitable for thick glass. They can be used with either light or heavy pressure. A 120-140-degree or 154-160-degree wheel is suitable for cutting most glass types. Some cutters also come with an oil reservoir.

Grozing pliers:

Grozing pliers are great for cutting glass with a curve or circle. They have a serrated edge that allows you to push or pull the glass but does not squash it like a lead knife. You can also use mosaic nippers to split or nip small sections from a glass rod.

Volume control:

If you are trying to make a fused glass sculpture, one of the key factors to consider is how to control the volume. Fired glass sculptures can have different shapes and sizes, and the firing temperature also influences the results. For example, a piece of glass 1/8″ thick will begin to draw in on its long sides and center. As the temperature rises, it will eventually turn into a flat-bottomed bead.
