Dear Clayart,
Alan wrote to me about the above glaze with a good observation. I think it
would be helpful to clarify it in general, so that anyone reading my glaze
test notes, will fully understand what I am trying to clarify!


Generally, the base raw materials in a glaze recipe add to 100 (or you can
make them add up to 100) for convenience.
Then, the colorants are added in, by percent, per 100 grams.

I will write the body of the recipe, and then at the end write ADD, and
those are the colorants to be added by percent (per 100 grams).

However, Alan, who is not sleeping in class..noted to me that in this
particular recipe,
the 9.8 RIO is a part of the glaze recipe's body, adding up to 100
grams. Therefore, when I say

Otherwise, the colorants are added exactly as they appear, to a 100 gm. batch.

It is such a help to get fine tuned about what we are talking about.
What I think is crystal clear could mean something totally different to
another reader. This sort of help and
backup is one of the things that makes Clayart such a fantastic source.

It is raining, cold and I just don't want to add handles. But I got to.
But I also have a lot of plastic. It is
a tough decision. I went to a Spinning class yesterday. Not weaving, but
crazy cycling, up hills, up mountains,
loud music, people of all ages between 16 (min. age in DK for body building
exercise) to 80. It was really fun,
my butt and underarms (you stand a lot) hurt today and so far, no sponsors
from Tour de France have called. But,
it is a lot of fun.
