Make It: Linear Reaction
This fun kiln-glass project harnesses simple chemical reactions to create a slumped plate with eye-catching special effects.
Clear stringers act as a barrier (or resist) between the reactive sheet glass and copper-bearing Turquoise. Wherever the Turquoise stringers overlap Clear, a Turquoise spot remains. Through the firings, the remainder of the Turquoise stringers react and develop to values of deep red.
