Wipe Your Bottom!
Correct glazing of your work is the responsiblity of the potter. Full stop. There are many different ways to do it correctly but it must be done on all glazed works. As a general rule leave at least 5mm from the base of the work before the glaze starts. If you are brushing the glaze on, be careful that you don’t go into this exclusion zone. If you are dipping or spraying use either wax or silicon to mask the bottom of the work. Simply dip your work into hot wax up to 5mm deep. That way the firing will burn off the wax and the work will be glazed with sufficient space, so that should the glaze run, it hopefully will stop before coming into contact with the kiln shelf. Use a clean, damp sponge to gently wipe away any residual glaze from the bottom. If you have any questions talk to your supervisor of the session for further details.
If you do have a glazing disaster the kiln team will notify you of what you need to do or pay for repairs.
