Slow Violet Opal


780.vopl is a violet tinted slow opal that opacifies in the flame and kiln. When reset, the glass is transparent violet, and when fully struck the glass is an opaque lavender  color.  Areas that have started to opacify in the flame will continue to opacify  in the annealer.  Striking temperatures are lower than that of our silver glasses.

Working notes:
This slow opal stays mostly reset during many beadmaking operations, and can strike to a misty-opal or opaque lavender color during annealing. I anneal this color at  975°F for up to five hours for semi-opaque beads, depending on size, encasement, and other factors.   Your kiln is probably different than mine. Test beads are recommended.
