    Anhydrous borax is sodium tetraborate proper, with formula Na 2 B 4 O 7. It can be obtained by heating any hydrate to 300 °C. [ 20 ] It has one amorphous (glassy) form and three crystalline forms – α, β, and γ, with melting points of 1015, 993 and 936 K respectively. α- Na 2 B 4 O 7 is the stable form.
