Yo Clubbers and Co.,
If anyone wants to try a free glaze calculation software...go to:
It's very simple, (without many features). It just allows you to calculate unity and save recipes.
It's completely free and there are no ads. Its just something that Mike Barber created for himself last year and introduced to a few potters.
Pass on the love, baby!
Take care and happy potting.-Mike Barber--A part time potter in Franklin, NC
