Attempted to do some casting today from the new molds I recently finished, but the temperature just was not high enough. At 60 degrees Fahrenheit my resin has not cured within the 60 minutes that the manufacturer specifies. I'm going to let them sit overnight before I clean out the molds just to see if the resin kicks, but this just shows how even 12 degrees can make a difference, and where a heated workshop is a great thing to have.
