Thanks for your thoughts, Definitely on some your lip hits the clay. It is a vitrified surface so the bare clay though rough is not sandpapery, it is glassified. I think the less thick glaze stripe at the lip, looks more balanced than bringing the glaze down much lower, as I did on some. Still, perhaps I should have brought the glaze down a bit lower on some.
Thank you sir, that was my target. These are of weighed 12 oz and 16 oz certified nontoxic talc-free Amaco #58 warm brown ^5, I do throw shot glasses and am prototyping drawer pull knobs off of the hump.
