All you older (doubt that) and wiser (likely) heads out there. I'd like to
check out a proceedure of mine. I have a formula for a white liner glaze
that someone worked out in two forms. One recipe is by the gram, the other
is by the cup. Have discovered that the by the cup formula fires better,
and the advantages of mixing a large batch by the cup are obvious.

So I needed to mix a large quantity of ^6 absolutely clear. So I carefully
measured a cup of each of the ingredients (nothing that should be either
hazardous or especially critical in terms of amount, flint, ball clay,
gerstly borate, custer). I weighed a couple of samples of each ingredient
to determine the gram weight of a cup. Then just converted a 10000 gram
batch to cups. Mixed and fired and it looks fine.

The question, Is there a down side I am not considering? Proceedure is
pretty simple, and sure makes for easier mixing of large batches.

You seem to be going about it the right way. The one thing to keep in
mind is
that the weight of scooped (i.e. shoveled, dipped) material is gnerally
NOT the same as material that is poured out as from a bag. If you are
heading towards really big quantities either make up several batches as
you
are doing now, OR "standardize" the way in which you
transfer the material from bag or can to the glaze bucket. Good luck.
