  • OH No I can't believe it!!!

    My favourite square mold has cracked!!

    I opened up my kiln this morning and there it was a great big crack in one corner, I think it runs all the way across.

    Are molds meant to do this? is it cause it's 2 years old?

    its true, they only have a limited lifespan.

    I guess you are using a plaster/flint/crystobalite mould (white in colour) yes?
    If so its true, they only have a limited lifespan.
    I'm not really sure why glass slumpers are so keen on using these type of moulds. I made some for my wife from a coarse clay and they are still going strong.

      Yes you are quite right, it was a white mold.

      Do you know of any where I can purchase a stronger mold?
