Hello, I’m a newbie here (and I’ve only been doing ceramics for 2 years).
Recently I’ve had an issue with my pots leaking. For the first eighteen months of me doing pottery there was no problem, but since June every single one of my pots/vases/cups has had a slow leak, like it’s sweating from the base, leaving a damp patch on the surface.
My great problem is that I have no control over the clay, firing or glazes used. I go to a pottery class, and our teacher is in charge of buying the materials and firing. I’ll talk to her more about the technical aspects of firing next week, but I want to get some opinions here before I do that. She says that there is no problem with the clay body, but the fact that this problem arose some six months ago in every pot, and not before that, makes me think otherwise.
I would be grateful for any input.
