**TERMOFOR** - a hot-walled device (usually used for cooking in ovens) that provides ventilation to remove steam and smoke through openings in the oven during cooking. A glass with a vodka is filled with hot water (the glass is 2-2.5 cm high). Place a piece of thin paper under the lid of the pan to protect the lid from destruction. This protects the top surface of the pans from soot produced by gas combustion. Such protection in principle does not require any maintenance.
Highlanders, shepherds, and tourists breathe in it. Steelmakers and metallurgists “breathe” in it. There are no secrets to thermophores
