Dear Ron and Clayart,
With the help Ken in Ireland's suggestion I will contact Potclays to =
find a frit substitute. Although I had such unhappy experiences with =
lime popping in their stonewares and raku bodies, well, if they can =
supply a good frit, of couse I can get over it!

However, that will wait two weeks, when I return from your side of pond, =
which I look forward to on Tuesday.

The frits I have available right now are listed as Raku frits.
They are=20

Fritte nr. 169
melting point 700c
mol. 205

0,086 CaO 0,006Al2O3 1,204SiO2
0,642 Na2O 0,846B2O3
0,123BaO
0,149ZnO


Fritte "J"
melting point 780c
mol. 235

0,214K2O 0,205Al2O3 1,884SiO2
0,417Na2O 0,452B2O3
0,366CaO
0,002MgO

Could the frit 169 be a possibility, as it has
MgO and very little alumina? But could this frit cause crackling,=20
and then of course I coudl not use it.

But I am willing to try!
Best regards,
Alisa in Denmark
