Usage Instructions

Stone's Handmade Use Instructions

• Apply to unfired or bisque fired clay.
• Acts as a colored resist before firing.
• May be left unglazed when on non-food surfaces.
• When used on a food surface, a suitable food-safe glaze must be applied on top of the pastels. 
• To apply glaze on top, first bisque fire pastels to remove the wax and oil and make them receptive to glaze.
• For best adhesion for glazing, bisque fire first to cone 04. If bisque firing lower, use firm hold hair spray as a fixative for easier glazing, as the lower-fired pastels are prone to migrate.
• Ceramics may be bisque fired many times without hurting the final product.
• If glazing, apply a stiff zinc-free clear style of glaze.
• Brush glazing may smear underfired pastels. 
• Fire to cone 6-10.
• Do not eat. Children may only use with supervision.
• Gloves or barrier cream recommended.
• As with all ceramic materials, test fire before using in production.
• Fire in a well ventilated kiln.
  
• Many decoration techniques are possible, so remember to experiment!
