I will add some photos for this post tomorrow.
Nothing is more dissapointing than spending time making a pot, trimming it and then glazing it only to have it lose it's bottom to a runny glaze.
Have you been having problems with your pieces sticking to the kiln shelves? Runny glaze that adheres to the shelf ruins your piece as well makes a mess for us kiln elves to clean off. Make sure you know if the glaze you used near the bottom of your pot - runs? If you can't answer that question just find a teacher or other student who can. Clean the bottom edge of your work enough to allow for a little movement.
Glazes that are on the move include , but not limited to Fog, Black, Floating Blue. Fog in particular acts as an accelorator. It makes the glaze beneath is run faster too. Never use fog on the area close to the foot of your pot.
The thinker the glaze the runnier it tends to be. Multiple glazes get runny to.
REGLAZING - Reglazing can save a piece but it's a crap shoot. Remember that the existing glaze will move and change as well as the new glaze you may have added. If your already glazed mug has a glaze right to the bottom edge, and you just want to give the lip a hit of glaze in a spot you missed - chances are the base glaze on the mug will move a little closer to the foot, and spillover to the kiln shelf and adhere.
