Ababi on sun 24 feb 02
After sending the letter below I remembered, I got the idea from an
adviser of supplier, that has kind of rare staff. When I asked him
for granular Manganese one said to the other: "Ababi looks again for
the strangest material".
Realizing that the delivery of Pyrite I wish to try would cost me too
much money led me to the next experiment, that like the letter
below,was a result of that telephone talk.
Today I took the claybody I intend to speckle.
I decided: 1.3kg of ready humid claybody is 1 K"g as dry,
I made three tests of 500 "grams" each
+8% red iron oxide
+8% yellow iron oxide
and the last 8% black iron oxide
To each test I added 5% borax
Made paper slip out of it and spread it on old newspapers.
I shall fire it to 750C 1382 F and smash it.
I hope I will get a speckling material. I hope the borax will add some
shine.
One advantage over the Manganese dioxide and the pyrite, will be the
ability to see the speckles in low fire.

>Hello Lela.
