I really hate to do this but, 1. I work alone and I don't have someone to bounce this off, and 2. if I'm wrong I waste about $80 in ceramic chemicals, and 3. I know some of you are math wizzes, and 4. (and this may be most important) I don't want to glaze 1000's of $$ of pots with the wrong formula.

Here's the situation.

I looked up from my chemical scoop to realize that my 500G weight was on the scale and wasn't suppose to be. Then I realized I was putting the wrong chemical in anyway.

So, here's the short version -- in one batch I have 1780 grams of a chemical that the glaze is only suppose to have 800 grams of.

In 4 other batches I have 1280 grams in the batch that is only to have 800 grams.

here is a list of other chemical and ther proper weights. Can you tell me what the corrected weight for each should be?

feldspar 4000 grams
kaolin 1920 grams
dolomite 1280 grams
zircopax 600 grams
bone ash 640 grams
iron oxide 80 grams

I know, I know......the math should be easy. But to quote David Wilcox, "The balance is no harder, it's just that you've got farther to fall!"

thanks for any help. Y'all were having a slow day anyway...

...weren't you?
