Turkey is home to 866kt (thousand tonnes) of
boric oxide reserves that, according to estimates from state-owned Eti Maden, constitutes 72% of global reserves.
They also contained about 18 percent
boric oxide, which demonstrates that boron is usable in copper reds.
The correct conversion factor is BAE = 1.2 x %DOT, because boric acid is 56%
boric oxide and DOT is 67%
boric oxide.
In the fourth stage of melting,
boric oxide (B2O3) was gradually increased to 0.5% in each composition while CaO was gradually reduced to 0.5% in each composition in the same way.
Borosilicate glass is made with the following approximate proportions of ingredients: 70% silica, 10%
boric oxide, 8% sodium oxide, 8% potassium oxide, and 1% calcium oxide.
Unfortunately, the acid leach oxidizes the surface of the boron carbide powder, forming
boric oxide, which prevents good metal infiltration.
Silica is the main acidic constituent of the more usual glaze frits and, with
boric oxide acting in a subsidiary role, is the main glass network-forming oxide.

Boric oxide, for example: if a ceramic piece is glazed with a white-opaque glaze containing an excessive amount of
boric oxide, the result will be a white-opaque layer in the glaze creating high reflections.
