This is my fist attempt at making a core drill mug. The first thing I did was throw an enclosed form. Then I turned it upside down and cut the bottom out of it and used it as the top. Then I hand built a bottom and a top for it. This mug is kinda small and this is a pic of it with under glaze on it before its been fired. I think on my next ones I am going to throw the lid and the base as well so it looks better.
