These crystals can be applied in 2 different ways, either sprinkle on while your last coat is wet or when applying the last coat of glaze you can dip your brush into the crystals and using a cross-hatched motion apply your last coat of glaze. The crystals can be mixed so try out different colour combinations.
When fired the crystals flow into the base glaze and have a gloss finish.
Recommended firing temperature is between 999°C-1046°C. Having said this they can be fired at any temperature but testing is recommended.
These glazes are lead free and AP non-toxic but are not recommended for surfaces that come into contact with food or drink.
