·Glass — Non-porous and non-reactive. Borosilicate glass (Pyrex-style) resists thermal shock. Tempered glass is 4-5x stronger than regular glass.
Longevity & Care
·Glass — Dishwasher safe. Handle with care — glass does not flex on impact.
·⚠ Modern "pyrex" (lowercase) uses soda-lime glass, which is less thermal-shock resistant than vintage PYREX (uppercase) borosilicate. Don't take modern pyrex from freezer to oven.
Cost Per Use
·Glass — Glass food storage and cookware lasts indefinitely. No staining, no flavor absorption, no chemical leaching.
·Priced around $275 (midpoint of $150–$400 for Home). At ~30 uses/month, this hits the $1-per-use "worth it" mark in 9 months — and falls to roughly 15¢ per use across a 5-year lifespan.
