Crystal Clay Mica Sparkle Powder will add a metalllic look to any of your crystal clay pieces. Mica Sparkle Powders can be added to varnishes, shellacs, waxes and acrylics for coating, painting and glazing. They can be applied dry to the surface of raw clay, mixed into raw clay, painted onto raw or cured clay (though most will have to be mixed into a moist medium, first), and so on. Mica powders are non-toxic and color fast, with a neutral pH, and though you wouldn't want to purposefully inhale them, they are less dangerous than metal pulvers. Not intended for cosmetic use. Quantity: Each jar comes with 1.5g Mica Sparkle Powder with a sifter inside to help keep your powder under control.
