SOKERO on tue 14 apr 98
Thirty years ago, my clay prof' said that the mine in Albany, NY for Albany
slip had been closed--and there was a limited amount of the stuff left. Is
this also a clay myth? JOY at the beginning of the Erie Canal (in Waterford).

Sokero...
That is a true statement... and it is very expensive (prohibitually so)
However, David Hendley , has a recipe for the stuff
so that you can make your own... (see msg below)... ....Marshall

Marshall,
I make my own Albany Slip substitute:
Redart 72
Whiting 10
Soda Feldspar 8
Talc 5
EPK kaolin 5
I can tell no difference in Rhodes Black made with this substitute
and real Albany Slip.
My 'Rhodes Black' is quite different than yours.
I've modified it over the years.
It uses much less cobalt, and manganese and iron take up the slack.
I've tried cutting back even farther on cobalt, but this seems to
be the minimum.
My Modified Rhodes Black ^10
Minspar (soda) feldspar 57
EPK 9
Redart 25
Dolomite 6.5
Whiting 2.5
Red Iron ox 5
Manganese Diox 3.7
Cobalt ox 1.3
110
This glaze is well balanced and has plenty of silica, but
with all those metals, I don't use it on food surfaces.
Re: your 'time savings tips' for glazes, why would you
put a 10 gallon plastic bag into a 5 gallon plastic pail before
filling it with a glaze material?
I use and like 3 pound coffee can for materials that are used
in small quantities. Because of the wide opening, so you can easily
scoop out material with a scoop.
