I have tried a few processes with variable success: -
- initial tests using the Hackspace reflow toaster oven at 220-230 C
- some fun with (cheap?) silicone cookware that breaks down at cooking temperatures!
- slight fumes but not unpleasant or dangerous - appropriate ventilation employed
Further tests at home in domestic oven: -
- cleaner process - using baking tray and baking parchment
- pressing into a plywood mould to make "slugs" for milling
