The piece is a strip construction (sys 96)-- 1/4" pieces standing on edge on a full sheet of clear irid, with the irid size down. There is a "smathering" of devit across one whole side. Hopefully, I can post some photos from a Flickr photostream:

Not wanting to admit it was devit, I tried soaking & washing in soapy water. Then, scrubbing with a scrub brush bought just for this purpose. Then, soaking in CLR and scrubbing with the fancy new brush... to no avail.
What would you suggest? I don't have a sandblaster, but I could hand lap (my lap grinder isn't large enough). But I would not want to sand or lap, anyway, because the irid side is down and so the irid coating would be sanded off. The irid side is the back of the piece -- I was planning to slump it on a stainless S-mold. I placed irid side down because I wanted the texture -- it seems to increase the "sparkle" and color spectrum when viewed from the front.
I used hair spray during construction (cheap, unscented) -- there may have been excess on the strip pieces because I got it half laid out and decided the design was not random enough so I disassembled, washed, and started again. However, the pieces with hairspray would have been on top of the irid, so I don't think that is the problem. The other thing is that the piece was fired on top of Spectrum's Papyros. I am going to be darned unhappy if the use of the Papyros caused the devit. i have always used Bullseye Thinfire with great success (no devit, less texture than kiln wash). Of course, I just bought a big roll of Papyros, after having good results with several sheets I bought for test.
Thanks for any ideas you might have on resolving the devit!
