Crystalites are a non-toxic glaze combination in a jar. These rock-like crystals produce dramatic effects that flow and melt during the firing process. Their usage is almost endless in decorating possibilities and is limited only with your imagination. Typically, a non-toxic formula creates a stiff glaze that does not allow the crystals to blossom or develop into colorful flowing arrays during the firing. This inhibits the vary nature of what you want to achieve in this type of glaze.
Crystalites are applied using a soft fan brush to shelf cone 04. The fan brush may help more in the even disbursement of the crystals, thus creating a more pleasing pattern to the glaze. Generally two coats of the glaze are applied from the jar after being shaken thoroughly, shake the jar before applying each coat. With application of the third coat of glaze, the crystals are stirred and shaken to suspend them into the glaze. Due to the nature of the non-toxic formula of the glaze, these crystals settle quicker and may need to be stirred more often while glazing. The brush should be swished down to the bottom of the jar to gather the crystals during the application of the third coat of glaze to insure a good coat of crystals are applied.
Although Crystalites are non-toxic and thus food safe when fired properly according to FDA standards, they may not be practical for food containers due to the surface characteristics.
