Hope everyone who celebrates the 4th had a fun day yesterday.
I'm gettng ready to do my third glaze firing and would like to mix up two of
the glazes I've tested into larger batches to fit in a 5 lb. bucket. I've
found three different dry ingredient amounts suggested that would fit in
this size bucket when mixed up and would like to know which of these I
should use. First one is 10 lbs. of dry, measured by moving the decimal one
place to the left; second is 10,000 grams, and third is to multiply each
ingredient percentage amount by 40 grams to end up with 4000 grams. This is
quite a spread in dry ingredient amounts.
Any suggestions?
Thanks.

I assume you mean a 5 gallon bucket, not 5 lb? In my experience, 10,000
grams will fit in a 5 gallon bucket, but without a lot of room to spare (or
to slosh when mixing). I usually make 8000 grams for my buckets. (multiply
your percentages by 80). Happy mixing!
PS, If you are just getting started with glaze testing, I would strongly
advise against mixing 5 gallon batches of anything. Test tiles often
(usually!) don't tell the whole story about glaze appearance and
behavior. I would suggest mixing maybe 2000 grams at most -- enough to dip
a real piece, but not so much that you will really regret it if it doesn't
work out. (Been there, done that, still have many gallons of unusable
glazes that I spent way too much time trying to salvage....)

A lot depends on the materials. For glazes with a
lot of frit, 10,000g fits well in a 5 gal bucket.
For glazes with a lot of gerstley borate (like 80/20
raku recipes) 5000g is about the limit. Those are the
extreme cases, and most other glazes fall between.

Rebecca,
For most glaze recipes, 10,000 grams of dry ingredients with the appropriate
amount of water will fit nicely into an empty 5 gallon bucket. When they
get too low to dip pots into, a 5000 gram batch is usually about right to
replenish them.

Rebecca - I usually move the decimal point out on our 100 gram
recipes to a 10,000 gram amount then split this in half to make 5,000
gram batches for our 5 gallon buckets. 10,000 grams will fit in the
bucket, but it's near the top and dipping larger pots will sometimes
cause the glaze to overflow the bucket.

I think you mean a 5 gallon bucket, not 5 pounds.
The quantity really depnds a lot on the ingredients. 10,000 grams with lots of
frit would fit into a 5 gallon bucket BUT 10,00o grams of fluffy stuff like
magnesium carbonate, wood ash or volcanic ash will not fit.
Try measuring out 4,000 grams. It should fit well into the 5 gallon bucket. If you
can double it, then go ahead and fill the bucket.
The one gallon buckets that mayonaise comes in for restaurants work well for 1,000
grams of glazes with frits , neph. syn., kaolin, silica, or those types of
chemicals. The light fluffy stuff al\ways needs more space.
Hope this helps.
