Ultra-Strong Adhesive called Water Glass also known as Sodium Silicate

Water, Lye and Silica Gel are used to make a product called water glass (also called Sodium Silicate). Mixing the Lye with the water and then adding the crushed desiccant packets will create a mixture that can be used as a high temperature adhesive. 

“Sodium silicate is the common name for compounds with the formula Na₂(SiO₂)_nO. A well-known member of this series is sodium metasilicate, Na₂SiO₃. Also known as waterglass or liquid glass, these materials are available in aqueous solution and in solid form. The pure compositions are colourless or white, but commercial samples are often greenish or blue owing to the presence of iron-containing impurities.

They are used in cements, passive fire protection, textile and lumber processing, refractories, and automobiles. Sodium carbonate and silicon dioxide react when molten to form sodium silicate and carbon dioxide:^[1]
