In the January CM in an article about Edward Eberle he gives his recipe for
terra sigillata in which he uses trisodium phosphate as a suspension agent.
I can't find it in the chemicals in my catalogs. Where can I get it? Is it
something like Calgon?
Thanks.

Selma,
I use trisodium phosphate (aka: TSP) to prepare and process plant fibers
for paper making. I picked up a box of the stuff at the grocery store for
about about a buck. TSP can be caustic - don't think you'd want to take a
bath in the stuff if you care for your skin. Intended use is for cleaning.

Trisodium Phosphate can be found at any hardware store. Personally I
wouldn't use it. It can be irritating to the skin. I've used Calgon
before. TSP is great for cleani9ng walls and things before painting or
applying wallpaper. By the way, the last time I did purchase Trisodium
Phosphate(TSP) the container said that it was Phosphate free - I just
can't figure that one out.

Trisodium phosphate is sold in many hardware stores. It's often used to soften
old paintbrushes, and I believe it's also used to scrub down mossy decks or
other wood-products exposed to weather.
Aren't Ed's pots magical, trisodium phosphate or no trisodium phosphate?

You can get trisodium phosphate from a paint store. It is used to wash
paint before repainting.
Calgon is a mixture now and I think it varies with the part of the country
where it is sold. It is perfumed. The old Calgon was sodium
hexametaphosphate.I have currently seen it sold at Dharma Trading Company,
a local fabric and fibre arts store and mailorder.They use it in water
softening treatment of dye baths.
(I am not affiliated in any way with Dharma other than as a satisfied
customer.)

I had a friend in school named Martie Geiger who used a paste of TSP on
her pieces. She fired it on and it made wonderful thick, white crusty
spots. Anyone else doing this? I never did watch her carefully enough
to see the whole process, but she always said there was nothing to it.

Does anyone have any experience with this material?
Thankyou!

Depends on what temperature you are firing at - not a problem at cone 6 but
above that there will be some sodium vapor present.
Lots of people fire soda ash laced shinos in fiber kilns - they should have
some observations for you.

One more use---in the laundry. I think the phosphates are the the chemicals that created such a flap and caused the soap people to redo their formulations. I remember pictures of sudsing in river waters, etc. I think it also had to do with the health of flora and fauna in or around the water ways. I'm all for cleaning up any of those areas. From my reading, mercury is the problem now.
However, I keep some TSP with my laundry soaps and add a scoop for things that are in need of a bit deeper cleaning. In other concentrations, it will remove paint, clean concrete--and I think it is used in the power washers used to wash the siding on houses. So, it is still out there but not in the concentrations of previous years when it had such an effect on the environment.
