We got two decommissioned lab drying ovens that can be used like a normal kitchen oven, with the important difference that these ovens are for non-food items.
According to the dials, they could reach a temperature of around 250°C. However, the nominal temperature according to the manufacturer is 220°C.
They have about 38 × 38 × 33 cm (width × height × depth) free space inside (about 2 cm more between the ridges on the sides, top and bottom).

House Rules
Use common sense - a running oven consumes a lot of energy and can even be a fire hazard. Therefore, do not leave an oven running when you leave the Space!
Uses
Feel free to try whatever is safe, i.e. certainly won't damage the oven or any people!
So far, members have used these ovens to...
- melt plastic (only with good ventilation!)
- cure paint or epoxy more quickly
- dry moist filament before 3D printing
- shrink-fitting: expand one metal piece to insert a second one (e.g. a bearing) that's been contracted by cold
- ...?
It may also be possible to temper metal after hardening - has anyone tried?
