I have a recipe from clayart for a cone 6 opal blue glaze (attributed to
Chris Schafale) that I would like to try. It calls for cobalt. I assume that
means oxide, not carbonate. Am I right about that?
Thanks!

My question has been answered off-list. I was wrong!
Thanks anyhow!

I tried this glaze with cobalt carb and got a very bright blue. To harsh
for me. But it is a very smooth glaze. My mix was more transparent than I
like in the blue. I really like the Floating Blue using cobalt carbonate
instead of oxide as it is more opaque and varigated.

Carole.
Check the amount, colbalt oxide is very strong, if the amount seems high, then its probably the weaker carbonate. "The Clay Stalker" Richard G. Ramirez - Sacto, Ca.

1) Opal Blue, by that name, came to me from Cindy Strnad, and is in the
archives in posts from her.
2) I always use cobalt carb, so if the recipe came through me, it has
cobalt carb in it.
3) Happy testing!
