I really learn a lot from and appreciate your replies. I really don’t belong on this board though. Pottery is a hobby for me. I throw fairly well but never more than one pot in a day. No way I’ll ever be great at it.
Seldom fire my kiln. I just don’t have the energy or ambition to acquire the education and skills you all have. I don’t sell my work but do give most of it to relatives and friends.

Sorry my questions are so pedestrian.
Thanks all
Best.
Ken
