Our Jungle Gems™ Crystal Glazes are meticulously crafted to mature at cone 06/05, but they can also be fired at higher temperatures. Please note that each product label provides guidance on performance at cone 6. As crystals have a tendency to flow at higher temperatures, caution is advised, especially on vertical pieces. We recommend conducting thorough testing on your clay body and in your kiln before regular use.
