Overview
This case presents laboratory chemical analyses of a glass-sand raw sample and a glass-sand finished product, tested for FOSHAN POWTECH / PTMS and reported in 2026. Those two labels are taken from the original reports.
The original reports do not state whether the material was processed dry or wet, or the equipment or process conditions. Values are shown exactly as reported. Titanium dioxide (TiO₂) is listed only because it appears in the original analyses; this page does not claim a reduction in titanium. No removal percentage is stated or calculated.
Test results
Both reports used method GB/T 4734-2022. Each submitted sample was a powder, about 160 g. Laboratory records, 2026.
