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

Non-Stick Coated Wok

⚠️ USE WITH CAUTION

Stir frying at high heat with non-stick surface

Materials

Aluminum base
PTFE non-stick coating

Common claims

Easy stir-fry cleanup
Non-stick surface
PFOA-free

Concerns / watch-outs

Wok cooking requires very high heat — exactly the temperature range where PTFE coatings degrade fastest
PTFE fumes at wok temperatures (500°F+) can be dangerous to birds and irritating to humans

Notes

The worst application for a PTFE pan. Woks are meant for screaming-hot heat, which accelerates coating breakdown significantly. Carbon steel is the correct low-tox alternative here.
