ParticipantHi Celeste,
if you have any fingernails left (after all the glass cleaning we have to do:), you can scratch the glass – one side might give a squeaky sound – this would be the irid coated side.
By the way, clear iridescent glass is one of my favorite, since it does not stick to Kaiser Lee Board. I’m using it in all my sculptural objects that need to look good from front and back.

Participantdo the same tests you would do for dichroic glass. Needle or pen tip touching glass. if reflection touches it is irid side.
Or view edge of glass. if slightly clear border (1/8 inch) it is the plain side.

ParticipantHi Paul,
Tried your method. I believe I can tell which side is the irid.
Thanks,

ParticipantHi Petra,
Hehehe… Fingernails, haven’t had those in years.
I’ve been reading some info on irids not sticking to fiber paper, etc… Will be fun to experiment with.
Thanks for the helpful info.

ParticipantHi Barry,
I tried the pen test and had a hard time seeing the reflection. Guess these old eyes need another checkup.
My bifocals don’t seem so strong anymore.
