Frequently asked questions

What SiO₂ purity does glass manufacturing require?

Container and float glass typically require 98%+ SiO₂ with tightly controlled iron content. Our glass-grade silica sand assays above 98% SiO₂ with Fe₂O₃ as low as 0.05%.

Can you supply custom mesh sizes?

Yes — our screening lines produce custom mesh fractions to match your process requirements, from coarse foundry grades to fine filtration media.
