Reactive Glass Colors
When two different glass colors are fused together, they
sometimes result in a third, totally unexpected, color. When
this happens, the two glasses are said to be "reactive".
In most cases, the third, unexpected color is brownish. It
varies in shade from light to dark, depending on the particular
glasses used. The color, which is caused by a reaction between
the ingredients of the two reactive glasses, appears wherever the two reactive
glasses come into contact, with the remainder of each glass being
unchanged by the reaction.
In the photo to the left, beads
of Bullseye's transparent turquoise glass (0116) have
been fused to
strips of clear and french vanilla opal (0137). Note that the
turquoise retains its color on the clear, but changes to a third,
color where the turquoise and french vanilla have touched and reacted.
When two reactive glasses fuse to form a third color, the
compatibility and soundness of the glasses is not affected.
Only the color has changed.
