Cast Iron Skillet

🌿 CLEAN & SAFE

High-heat searing and oven-safe cooking

Materials

  • Seasoned cast iron

Common claims

  • Naturally non-stick when seasoned
  • Lifetime durability

Concerns / watch-outs

  • Can leach small amounts of iron (usually a positive for most adults)
  • Heavy; can be awkward to handle when hot

Notes

One of the safest, most stable cookware materials when properly seasoned and cared for.

Cleaner alternatives

Glass Casserole Dish

🌿 CLEAN & SAFE

Baking casseroles, lasagna, and oven dishes at moderate temperatures

Materials

  • Tempered or borosilicate glass

Common claims

  • Oven-to-table serving
  • Non-reactive surface
  • Easy cleanup

Concerns / watch-outs

  • Tempered glass can shatter with thermal shock — avoid moving from freezer directly to hot oven
  • Borosilicate glass is more thermal-shock resistant than standard tempered glass

Notes

One of the most inert baking surfaces available. Choose borosilicate glass for better thermal shock resistance. Avoid the broiler, which can create extreme temperature differentials.
