This is something I can use right away with my glaze containers. I will be mixing the bentonite, epsom salts and CMC to keep when needed. Thanks for the info, John!
Great John, thanks. I don't want to use bentonite as it contains iron. I'm trying to stop hardpanning in a white satin matte for use on porcelain. I've changed the formulation to replace ball clay with china clay to exclude the iron so don't want to add it back. I'll try epsom salts in the hope there is enough clay in the glaze to make it work.
John, Thank you for teaching us something very useful! I have a big bucket of carbon trap shino but the soda ash in it has formed huge crystal chunks. Anyway I can fix that?
Thanks for the video John. I like the idea of keeping Bentonite in a pre-mixed state for testing. I will try that, however how can you know exactly how much you added to your test when you go mix up a big batch of that glaze? I suppose a little guess work is fine.
If you can weight it out with the recipe that is best but I just have that for emergencies. But you could figure out the amount in the cup and then estimate the amount in a tablespoon.
That was awesome! I'm having this problem with one of my glazes now. I can't wait to try this to fix it! Thanks for all of your awesome videos!
John, I've needed this info for a long time. Thanks for the clear demo.

you made my day today!
struggling with a hard pan glaze, did not know how to fix it. But you did ;-) Thanks a lot!

The iron is negligable, but you can use Macloid or Vee-gum T..no iron
@@johnbrittpottery Thanks again, will do a test with bentonite
Fantastic!

Clear as a bell. Thanks!
Hey John how do you get rid of marbling in a glaze without making it thicker?
You have to add Epsom salts and then add water.
Thanks,John. Just what I needed to know.
Pass the word!

Hi John, What is the equivalent of CMC and Epsom Salts in U.K? Thanks for your video and help.
Can we deflocculate using darvan 7 or darvan 811?
Yes
How do you keep porcelain slip from hardening?
I put it in a bucket with lid.
Thanks John. You Rock!
Why my clear glaze is smelling?
organics...put in a few drops of bleach to kill the bacteria.
