Tried to put opaline striker over BE turquoise and it has turned brown. Have not read anything that suggested it was reactive........Any suggestions?

Pics, please? Are we talking frit, sheet..?
It's not supposed to contain copper-reactive stuff (sulfur/selenium/lead)...so are you sure it's opaline striker? Could it possibly be reactive cloud opal or translucent white? Both of those look sorta like opaline in the raw state and they definitely will react...

Sheet. Definitely opaline striker. The only thing I can think of is maybe my kiln temp is off from the 1490 suggested top temp. I am refining one piece as a test tonight.

Test piece came out from second firing (in a different kiln) just the same as first, dark, dark chocolate brown over the turquoise opal. Stumped.

Hmmm. If you have a piece left over, try firing it on its own, without the turquoise. This one's really got me going.
