Dear Debra,

Try Degussa`s Intensive red. Yes ,it is expensive, however
very little goes a very long way. Just one or two grams are sufficient in a
recipe. It is food safe. Ceramic King in Albuquerque carries it- they are
on the Internet. The number I have written on my jar in which I store it
is Z2796 LG5D. I am sure there must be other suppliers .
Mason`s stain #6385 Pansy Purple in a glaze that is zinc free, gives a
good purple.
I personally have not found a decent pink or red stain that is not
fugitive and ,for the latter color ,'food safe, until I found the Degussa
brand. Another way to go is to buy Amaco`s Velvet underglaze V-383 or
V-382 red, which is lead free and fires to cone 6. Buy the pint size which
saves about $7.00. It is food safe if topped after the bisque firing with
a transparent glaze. Hope this helps. Mia in ABQ where the annual State
Fair has begun.

Anyone know how these encapsulated cadmium stains stand up in ^8 and up
glazes? Are they foodsafe in all circumstances?

I've used this stain in a simple high calcium ^8 glaze, with boron and
strontium minor fluxes. Used alone, the stain gave me a cold purplish blue
I didn't find very attractive, but with 2% of titanium dioxide, the color
became much warmer-- more of a true purple. I have no idea why this should
be so, but I offer it for what it's worth.

I have used several different colors of DeGussa's stain.....the inclusion
stains. I have found that i do not get good color with less than 10%.
and even better color at 12%. Im not sure what you would get with only 2% -
3%.
