If we all always add a zero in front of our decimals, we can avoid this sort
of confusion. "0.5" is a lot clearer than ".5". Lets all make the extra
zero before the decimal standard in the glaze recipes we trade.

Alisa and Claus Clausen on wed 6 dec 00
Dear Group,
It is so great to have people reading and checking and helping.
The following mistake was seen by Andy Buck.
This glaze had 4.5 % too much cobalt for breakfast.
Should read 0.5 cobalt, not 5.0.
It appeared as .5.=20
I cannot see those tiny dots sometimes.
AND, I was just getting sort of mildishly cocky that I was beginning to =
recognize=20
porportions in receipes. Like recently when I had 80 zircopax written =
down for=20
a hundred gram receipe. Well, that would be obvious to most novices, =
but I am
getting better at recognizing sensible porportions. Sure did MISS this =
one, however.
Thanks a lot to Andy for holding check on me. She/He? also said that I =
must have meant
Tong Man, not Tang Man, which is also correct. Claus does not refresh =
me with that orange moon drink
at the raku site! Tang is also kelp here, as it is also a tong. =20
OK, will retest with 0.5 cobalt.
Best regards,
Alisa in Denmark

=20
Personal:
BUT, I do not know what this glaze ate for breakfast, but it spit all =
over like crazy. It jumped over to a pot next to the test and left a =
huge halo of blue on the
shelf and on the adjacent wall.
