Today I attempted to turn a pot for the first time. I only had one pot to attempt with and unfortunately it was unsuccessful. I made the common newbie mistake of over-turning the base until it was too thin and so the middle would concave slightly making it impossible to even create a flat smooth base.
Two things I successfully learnt include tapping the bowl in to the centre and sticking down with clay and tapping the bowl to determine thickness. (I was shown this only after having made the base too thin, so couldn’t utilize this technique to prevent the failure.)
