Description

A white, water soluble powder. Sodium borate is found in nature as Borax. Borax is produced by the evaporation of water in shallow lakes. The white powder is mined from deposits in India, Russia, Iran, and and the U.S. (California). Sodium borate is used as a Flux, Cleansing agent, tanning agent, fireproofing agent, and as an Alkaline ingredient in Glass, Ceramics, and Glazes. It is also used in the developing bath for color photographs. Sodium borates are used to kill Cockroaches, and as an antifungal agent for wood. The slow acting material has also been used to clean and provide long-term inhibition of Algae, Lichen, and moss on monuments (Richardson 1973).
