Nws yog feem ntau pom nyob rau hauv rhyolitic lava ntws hu ua obsidian ntws, qhov twg cov tshuaj muaj pes tsawg leeg: cov ntsiab lus silica siab ua rau cov viscosity siab, uas ua rau cov cua txias sai sai hauv cov iav lava.

Qhov inhibition ntawm atomic diffusion los ntawm lub lava nplaum heev piav qhia qhov tsis muaj kev loj hlob siv lead ua. Obsidian yog tawv, nkig thiab amorphous. Yog li ntawd, nws tawg nrog ntse npoo. Nws tau siv yav dhau los hauv kev tsim cov cuab yeej txiav thiab stabbing, thiab kuj tau siv sim ua cov hniav phais hniav.
