i have to agree with Monika that your efforts are admirable. they remind me of
very early potters' efforts! speaking of early potters on some continents,
before they had the technology to fire hot enough to flux glaze material, the
way they made their pots (somewhat) able to hold water was by burnishing: i.e.,
compacting the aggregate into the clay and getting a "glaze-like" finish, which
helped create a somewhat non-porous finish. i'm mainly thinking of the native
north and south americans. however, i'm with Monika in recommending that you
utilize some modern conveniences. if you could bisque fire the ware, even to
cone 015, and then pit fire them with cow dung, sawdust or whatever, you could
come up with some very nice pieces.

good luck and cheers to you for your spirit! i loved

i look forward to hearing of your results.
