Kool-Jool In 8 oz Jar GemOro these Swiss Made carbide roundKool Jool is a protective gel designed to shield heat sensitive stones and organic materials during soldering. Applied directly to stones or surrounding metalwork, it acts as a thermal barrier that absorbs and dissipates heat before it can reach delicate materials. Whether you're working with organics like pearl, coral, and amber or fragile mineral stones such as emerald, turquoise, opal, or dyed stones, Kool Jool helps reduce the risk of heat damage
