PH (acidity) levels of polymer clays

Does anybody have a chart of the PH levels of different brands of baked polymer
clays and liquid clays?

Thanks,
Tracy

Hi Tracy,

Here's some stuff I have at my website that relates to that at least somewhat:

baked Premo and Sculpey III are "acid free (neutral pH) and lignin free� so
they should be fine to use in fine scrapbooking, etc. if properly and
completely cured. . . the sculpey.com website says . . ."“Polyform’s
chemists have been conducting tests on the clay for quite some time. All tests
indicate that . . .

....does anyone know about these though??
--Sculpey --SuperSculpey --Fimo --Kato Polyclay --Cernit
--and liquid clays from all 3 manufacturers????
......liquid clay transfers of all kind swould certainly be cool in scrapbooks,
and thin too. Diane B.

....I suppose we could get some pH strips and do some testing ourselves on
those. I have a pond and have to get some anyway to test the water.... so the
acid-free property is still in question. . . . However, I think we can safely
say all those are lignin-free because they are not made from plant materials .

....According to some of the literature I've found, it was common to see carbon
steel knives quickly tarnish when exposed to strong acids like citrus fruits.
Strictly as an experiment, if any of you are desperate and curious enough, you
might try pH testing your clay to see if the pH is low (acidic or in the pH
scale below 7). If there is such a thing as acidic polymer clay, perhaps mixing
in a tiny smidge of baking soda to raise the pH could neutralize the clay and
reduce corrosion/tarnishing (what we call streaking created by a pasta
machine). Desiree
