Cone 5-6
 
Natural Opal is a glossy, semi-transparent glaze that is as versatile as it is beautiful! A stunning white glaze at first glance, but upon continuous inspection you will witness the subtle hints of various hues reminiscent of a precious stone!  Natural Opal is great with a standard application and is even more precious when layered with other colors.
