I offer quality handmade muffle (batch) furnaces which perfectly suit both - ceramics baking and metal heat treatment or melting, you can also use them for enamel baking and other manipulations requiring high temperatures.
Thermostat rex-C100 or TPM251. Heating element is superfechral. Maximum temperature – 1200C. Material – steel body + ShVP550. You can easily replace a dead heating element, I can also supply a spare one (if you need and require it).
