Dichro help
About 5 years ago I bought a bunch of dichro strips. I used one today and there was a lot of scummy film through out. I was careful to seal the edges so that the flame did not hit the dichro. Does dichro go 'bad' after some time?
Is there any way to clean it?

is it "pre fired"? if it's not, and you used it before firing it (ie: affixing the dichro to the glass via hot kiln cycle) this may happen.
but i'm used to boro.....

Cecilia, I find that my newer dichro is much nicer than my older stuff. I don't think it goes bad, I think vendors have gotten better at preparing it for sale. JMHO.
You might try making dichro stringers out of the old stuff. That's what I did: cut into pieces, pre-heat in kiln, take one out and coat all over with clear, melt into a gather and repeat. When you have a nice size gather, pull.
HTH,
Helene

I am not sure if it was pre-fired. I got it a long time ago.
Thank Helene, I will do that! By the way who is the best source to buy 104 dichro these days?

Not the cheapest, but the best is Coatings by Sandberg in CA. You can call and ask if they have any scrap of 104 (if that is what you're using) and start off with that. I would buy dichro on clear, and fire it in a kiln before using (to at least 1350).

Make sure that your edges are very clean, especially if they are raw, cut edges. I wipe mine down with alcohol and white vinegar just before using. Also, if they're raw, a firm swipe of clear or the base color of your bead on the edges can help seal it.
I'm a fan of Lori Riley for dichro. She worked for Arrow Springs for many years and produced the best dichro strips I've ever used. https://www.facebook.com/RileyDesignsDichroicStrips
