Glass Packs safety

Borosilicate glass resists thermal shock, but there's always a risk that extreme temperature change can cause a crack in the glass. Use caution with hot to cold or cold to hot temperature changes. Glass is breakable. Do NOT use if glass is cracked or broken. Promptly and safety responsibly dispose of broken glass immediately.
