    Re: Tarracotta Flower Pot Oven -- using two flower pots

    could you make pieces from clay, dry them and fire them in the brick oven?

    i got my oven hot enough to melt wine bottles. would that be enough to shrink and provide some level of firing?

        Clay undergoes the irreversible change at 573 C so that it won't return to mud if water is added. Glass usually melts at around 900C but every glass is different, artists who do glass slumping test each glass they use. Some even have a plastic content which makes them melt at an even lower temp.
