I do agree with Suzan K about the two possibilities for the blowing up of your mold.
Conserning the firing of the low firing clay,I suggest you to verifiy with the maker of the clay.
When I made my molds of low firing clay I used the code “cone”firing schedule.I have the option between glass or ceramic firing.Pottery (clay) is not as difficult to fire than glass.When I used cone firing,I had the option low,medium or fast firing.I used cone 08 (1750*F) .It went to room temperature to 1750*F. Than at 1750*F I shut down the kiln(at off).
The next morning, the mold was fine and I still used them often.Sylvio
