What to Consider

Materials & Construction

·Stainless — Highly resistant to rust, corrosion, and staining. Non-reactive with food. Professional kitchens rely on stainless for a reason — it lasts a lifetime.
·Glass — Non-porous and non-reactive. Borosilicate glass (Pyrex-style) resists thermal shock. Tempered glass is 4-5x stronger than regular glass.
·Made by MiiR in United States.

Longevity & Care

·Stainless — Dishwasher safe. Preheat before cooking to prevent sticking. Use Bar Keeper's Friend to restore shine.

·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

·Stainless — A $150 stainless pan used daily for 20 years costs about $0.02 per use. Non-stick alternatives need replacing every 2-3 years.
·Glass — Glass food storage and cookware lasts indefinitely. No staining, no flavor absorption, no chemical leaching.
·MiiR is known for products that hold up over years of use — which typically means a lower cost per use than cheaper alternatives that need replacing.
·Priced around $30 (midpoint of under $50 for Kitchen). At ~25 uses/month, this hits the $1-per-use "worth it" mark in about a month — and falls to roughly 2¢ per use across a 5-year lifespan.
