What to Consider
Materials & Construction
- ·Glass — Non-porous and non-reactive. Borosilicate glass (Pyrex-style) resists thermal shock. Tempered glass is 4-5x stronger than regular glass.
- ·Made by Seams To Fit in United States.
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 $100 (midpoint of $50–$150 for Accessories). At ~12 uses/month, this hits the $1-per-use "worth it" mark in 8 months — and falls to roughly 14¢ per use across a 5-year lifespan.
