Cookie Redding on mon 26 oct 98

Greetings Clayarters! I have a question for everyone interested. At
my grad school we have this really nice yellowish crackle raku glaze.
I wanted to mix it up for myself, but find myself stumbling over one
of the ingredients...the recipe is as follows:

Naples Raku
Frit 14...............720
EPK...................80
ERS...................8
Naples stain..........64

Ok. Now the question is as follows: What is ERS? Also, come to
think of it, is the frit 14 a ferro frit or what??? I've exhausted my
limited resources and would appreciate any of your guys' help! Thanks
in advance to all who help!!!

Cookie:
Frit 14 is Hommel Frit No. 14, and it is equivalent to Ferro Frit
3134 and Pemco Frit P-54, and Fusion F-12.
As for ERS, that's first I seen of it; and I wonder what it is,
an actual material or a typographical error.

Hi Cookie,

I just love a good mystery - the ERS is exactly 1% of the recipe - with all
that frit I will bet it's bentonite. Can't be epson salts - at 1% it would
be too much. Surely there must be others who can find some other clues - I
checked the Conrad Compediums - sure had a lot of lead raku glazes - RR
