Unlike shock compression, the pressure exerted is steady, and the sample can be heated using a furnace.
The closure temperature of a system can be experimentally determined in the lab by artificially resetting sample minerals using a high-temperature furnace.
The heating is performed at temperature of about 2000 C using a furnace or an arc-melting setup.
This used a corrugated tubular furnace and cylindrical outer firebox, as for the Lentz.
It is using a rotating furnace to make the mirror.
These temperatures are experimentally determined in the lab by artificially resetting sample minerals using a high-temperature furnace.
Crazy, Minna thought, to be using a furnace in the spring.
The Angel system uses a rotating electric furnace about the size and speed of a carnival carousel.
The most successful of these was puddling, using a puddling furnace (a variety of the reverberatory furnace).
Annealing (glass) and glass blowing probably occurred using a smaller furnace.
