 The discovery of borax as a cleaning agent opened a new industry. Research on the uses of the other borate minerals created a demand for the different minerals in the late 20th century. Even "slime" which many children love to play with contains a borate mineral. All the uses for borate minerals have probably not been discovered. What will be the next discovery?

SLIME

Slime works when you get a substance to bond with the molecules of Borax (sodium borate). Polyvinylacetate (white glue) and other substance mixed with borates create new molecules (polymers). For example white glue molecules are long to begin with, and they are tangled, which is why the glue is so viscous. Once the Borax links up some of the molecules, it becomes even more viscous with a slimy feel.
