Wissmach Art Glass for Cold Working – Stained Glass, Architectural Glass and More!

We will be adding images of all our current glass colors, as we produce them. In the meantime, please refer to our PDF catalog, if you don’t have the printed version on hand.

We call this glass Art Glass, versus our Kiln Glass, which is specifically made for glass fusing and kiln forming. Our Art Glass is not tested for compatibility and also might devitrify, if you are firing it in a kiln.

Cathedral in the traditional Stained Glass terminology means also transparent glass. We have a wide variety of colors. Any of the cathedral colors look beautiful with our patterns.



English Muffle

 English Muffle was originally produced by Chance Brothers in England until they went out of business in the 1930s. In the 1980s Peter Foster, an insurance executive from Adelaide, Australia, was looking for a hobby in anticipation of retirement. He settled on restoring lead lights and stained glass windows and along this path he run into some challenges.

   Peter found out that there was a tremendous amount of the original English Muffle glass (produced by Chance Brothers) in his restoration projects. At first he was able to find some of the needed glass at the salvage yards. This source did not last very long and he had to find the glass somewhere else.

   A glass manufacturer in New Zealand agreed to make the glass for him, after he was able to get the texture roll made by another New Zealand manufacturer. In the beginning of 1987 the first sheets were made but unfortunately the stock market crash in October 1987 put the New Zealand glass manufacturer out of business.

   Peter Foster did not give up and was able to retrieve his roller from the glass manufacturer and contacted Wissmach Glass to see if they had an interest in producing English Muffle. A few phone calls later he got himself a ticket and brought the English Muffle roll (they are made from steel and are heavy) to Paden City. What he did not consider was that our rolling machine was a lot bigger and the roll he brought did not fit. We agreed to send a blank roll to the company that made Peter Fosters original English Muffle roll in New Zealand and the rest is history. Wissmach glass was able to duplicate Chance Brothers original 32 colors and Peter was able to continue with his hobby.

Opalescent, Wisspy and Streaky

We do have 4 groups of color density and light transmission in this big group of colored art glass. Most of the colors are a mix of glass, which we call Prisma in the Kiln Glass and could also start calling them Prisma in the stained glass. A lot of companies call their color mixes either streaky or wispy. Probably taken from our names, since we were the first ones in the industry mixing glass colors to create the beautiful glass sheets.

But Streaky and Wisspy atcually do not refer to the color mix, but more of the light density of the glass. In addition we have D-glass and L glass.

Let me explain

D – stands for a dense opal base – and opal in this case means white + the colors

L – stands colors mixed with a slightly translucent white

WO – stands for Wisspy Opalescent which has a light density and allows for some light to come through, which gives the glass some high light. 

Streaky also LL – stands for a color mix with only crystal (clear) glass

XX – stands for single opal color
