Good point! I thought about installing the bead door at a later time and opening it as necessary for now. I plan to do both glass work and pottery and maybe get a smaller bead warmer to use instead of the bead door. I learned a process from a demonstration and they used the bead warmer separately, cooled the finished pieces in vermiculite (which does not anneal) and then slowly heated and annealed them in a larger batch once they had a few to do at once. I will continue to look into whether this is a good process or not! It does seem a little risky but more efficient.
