Montmorillonite - a first cousin to bentonite.
Clumping litter puffs like crazy when saturated,
and re-shrinks as it dries - not a great choice
for a conventional glaze, though it might do as
an additive in small quantities.

So going through the archives looking for mocha glazing ideas, I found
Martin Webb's cat litter glaze! Of course I'm curious...is this pre- or
post-scoopable litter types? Straight clay stuff? (I have no idea what's
in scoopable litter that makes it clump...)
Martin also says it's for cone 2 oxidation...any chance of using it at lower
temps?!
I can't believe I'm asking about this...

The late Martin Webb was also into recycling used cat litter,
which truly put an awful lot of people off even thinking about
following in his footsteps, Kate! The problem (as I recall) was
getting high enough clay content, but exactly how he judged, I do
not remember. I should because I was looking for a kitty litter
and plaster mix myself and we compared notes at one point. I do
know he was preheating to get rid of the cat poop and urine (I
know, gross, but that was his vocation) and then
grinding/seiving, which meant that other materials and aromatics
were burned off.
But he would be pleased to know someone was willing to try his
recipes! I remember he fired very, very low.... At least as low
as possible with the clay he was using (for environmental
reasons). That is as far as it goes since all my e-mail archives
were lost last year and I had no backups... So no other
information, sorry. There was a potter in Holland, who may know
something more because he spent some time with Martin at his
Webb's Cottage workshop. I do not think I have his e-mail address
any more, but will check if he is no longer monitoring Clayart
himself.
If it is chemicals used to "clump" kitty litter as you describe,
then surely calcinating a few hands full and then testing using
Martin's recipes would not be too difficult? Then you can update
the archives with your information!? Good luck!
