This UV glue is cured with an activator instead of an expensive UV light. This makes it ideal for gluing glass to glass, even opaques, which a UV light glue can't cure. It is great for glass to glass fusing, mosaics, three-dimensional stained glass and jewelry, among other applications. In addition, it's also well suited for gluing metal to glass (like jewelry findings) with fast and easy cleanup. You can even use Triolyse with stone such as granite or marble. Package includes 14ml of activator and 10ml of adhesive.
