  1. Thanks I will search for veegum, hopefully after lockdown has eased I will be able to source some to try!
  2. Thank you so much for your detailed explanation, I'm going to test with the ball clay, my clay is wet so your wet calculation helps alot! I'll stay clear of the bentonite.
  3. Thanks for your help, I will try to do so, technology is not my strong point ☺️
  4. @glazenerd I use a local South African white midrange stoneware clay which fires to cone 6. It is extremely short and I read that adding a 50/50 ball clay to bentonite mix will improve the plasticity. They recommend to add 50g to a kilogram of clay. Will this influence the cone my clay fires to? At first I thought it was short because it was freshly made, but I'm 6 months down the line and it's still short. It even cracks when I wedge and it's not dry. I think it might have neph sye in it because if I wedge normally it cracks like crazy, but when I stack and slam it becomes pudding like.
