Flux

In order to receive a glass pellet, we need a substance called flux.

The most common fluxes are:

lithium tetraborate (Li2B4O7) of fusing temperature 920°C
lithium metaborate (LiBO2) of fusing temperature 845°C
mixture of lithium tetraborate with lithium metaborate, e.g. 66:34; 50:50, 35:65
the fluxes exemplified above with additives, such as: LiBr, NH4I, LiI
