Reactive Glass Colors
This is part two of a
multi-part series on reactive glass colors. Click here to go
to part one.
When two glasses come into contact during fusing and create a
third color, this is almost always caused by specific ingredients in
the two "reactive" glasses. The most common ingredients which
lead to a reaction are sulfur, selenium, copper, lead, and silver.
As the chart below illustrates, reactions between these ingredients tend to fall into seven main categories.
X indicates a reaction between the two ingredients
1. Copper - sulfur reaction
2. Copper - selenium reaction
3. Lead - sulfur reaction
4. Lead - selenium reaction
5. Lead - silver reaction
6. Sulfur - silver reaction
7. Selenium - silver reaction
Coming soon -- a list of reactive glasses for each
of the categories above.
