Quick Tip: Working with Petrified Wood

Petrified Wood is Bullseye’s magical unicorn streaky. Its unique combination of glasses results in dramatic internal reactions at full-fuse temperatures. Here are two ideas for making this glass sing.

 

Copper Reactions
The Clear areas of Petrified Wood contain Red Reactive Clear, a style that reacts with select copper-bearing glasses, developing deep red hues where they meet. Neighboring sepia-hued areas develop a variety of rich, earthy effects.

Tips

Base: Robin’s Egg Blue (000161-0030); Cap:Petrified Wood (002971-0030) Mold: Square Nesting Plate (8758), medium.

 

Displacement with Frit
Sepia-hued areas of Petrified Wood strike with varying opacity and colors. Play up this organic effect with various grain sizes of Clear Frit. We used Coarse and Extra Large. The frit rounds out and sinks in, creating shallow pools.

Tips

  • Leave space between the grains and give them room to melt and displace the underlying glass.
  • Expect variation to occur within a single sheet and throughout production runs of Petrified Wood.
