Stained Glass

Glass- The main ingredient that makes up glass is silica. There is a combination of other substances mixed with silica, such as potash that are put under high heat to chemically transform the material. Metallic oxide powders are added to alter the colour of the glass, giving us a wide range of colour choices. There are many types of glass, which differ by their manufacturing methods, such as: Cylinder glass, Crown glass, Rolled glass, and Flashed glass.

Came- The metal which holds the cut pieces of glass together is called came. It is traditionally made of lead, zinc, brass, and copper.

Copper Foil- An alternative method to using metal came is copper foil. It is particularly useful for smaller projects or precise shaped designs, such as lamps. The edges of each piece of glass are covered with adhesive copper tape and then soldered together.

Stain- Silver nitrate is used to stain glass. It ranges from a pale yellow colour to a rich amber, depending on the amount of material used and how long it’s fired in the kiln.

Putty weather seals a window

Putty- The final step to finishing a piece of work is to putty it. Putty helps seal a window from weather and hold the pieces of glass in place. A mix of chalk and linseed oil works well.
