Thank you for any help you can give me on the salter......by the way, I
wrote earlier that I was trying to use local materials, with a small
particle size and get 06-04 neutral or ox. glazes that were nice with
minimum dependence on imports....well down by the dry creek bed, we found
the most amazing albany slip/stuff, that just falls through 100 mesh sieve,
and makes a beautiful and I mean beautiful St. John's black and gorgeous
tenmoku with borax, kaolin and a little lithium and zinc .... they look like
cone 10, can't scratch, hard as a rock...also having great success with vol.
ash at those temps too, but have to add some 3134, but only 27%, everything
else local.....the jade glaze is a truly beautiful one, didn't want to have
to add anything additional for color, but couldn't get anything, with many
many trials of different fluxes and materials, but either mustard or various
avocados....so added some of the above mentioned river slip and very little
cu carb and have a lovely gray green irridescent hard shiny beautiful
surface with some mottleing and variation...it's mostly pure powdered jade
so don't feel like I'm really cheating to add a little copper carb and my
river slip to the mix ....the jade makes whatever glaze it is in just smooth
out and have the most beautiful hard finish.....these glazes are
amazing...no blemishes, crazing, even when I pull them out of the test kiln
still glowing..they are the best glazes I've ever made....I can make them
really thick and fat on the pot..speaking of pots, the toilet factory in
Guatemala City has 400 m. silica and balls clay, etc, so I think I'm going
to be fine...in fact, if I hadnt been so desperate, I wouldn't have found
the wonderful glazes that I have and would still be watching everything
bubble and craze at 06-will continue to prospect for new materials, to sub
for frits..you never know...I wouldn't have thought I would have an endless
source of a great albany type slip here and now that I do, who knows, a GB
substitute may be under the next rock...enjoy reading your posts....Melinda
in Guatemala..
