I can't give you a numerical answer but can share a bit relating to the
experience. I cooked mine in an aluminum turkey roasting pan in a
covered Weber charcoal BBQ grill. It took about 2-3 hours to melt to a
thick, mostly-liquid viscous state and could not possibly have been done
indoors in a controlled oven, due to the smell, if that's what you're
thinking. I should add that the case leaked melted tar and was a pretty
horrible mess. Since my goal was de-potting and re-potting in melted
vasoline, I can't comment on time to repair carbon tracks.
