Evidence context

How this source is used

Evidence roles describe what this source helps establish inside each Investigation. They are local to that use, not permanent labels attached to the publication itself.

Investigation

Does stomach acid digest swallowed glass and make it safe to swallow?

Qualifies

A controlled materials study observed composition-dependent surface alteration of commercial glasses in acidic solution.

4% acetic acid, pH 2.4, 70°C, 1096 days; approximately 0.88 ± 0.05 μm sodium-depletion layer in the examined soda-lime glass, not a measured whole-shard gastric dissolution rate.
