For polishing the bottom of pots and around lids and galleries
usually emery paper does the job for me but when more
serious polishing is needed I use a concrete paving block
(commercial) which has a perfect glass like surface and
sprinkle on some silicon carbide powder and a splash of water
and grind the bottom with a circular or figure 8 motion.
As the powder grinds down in size and mixes with concrete powder=20
the mixture changes to a finer polishing action. It works for me !!!
For the odd glaze drip at the base.I grind with the side of a=20
ceramic cutting blade in the saw bench.fairly gentle and effective.
much better the an emery wheel and less likely to chip the pot.
