Luminescent

 Tips on firing Wissmach Luminescent glass: 

  • Firing with the coated side down on a powdered kiln wash dusted fiber shelf will intensify the coating.
  • Firing with the coated side down on a kiln washed shelf or shelf paper will keep a bright coating.
  • The color will stay vibrant on dark colors but will fade on lighter colors when fired with the coated side up.
  • The coating will not be visible when fired with the coated side covered by another piece of transparent glass.
