The last year, I'm seeing more beads offered on Etsy advertised as "aged" Picasso beads. They're mostly Czech glass beads, often seed beads (from 1/o through 12/o), with a Picasso coating, often matte finished. I've included a couple of pics.

I've purchased ordinary Picasso-finished beads in the past, not nearly as expensive. These examples often include what looks like new striped pony beads, which are usually very cheap.

I've been trying to find a wholesale source, because these are so expensive (for new Czech glass beads), often running 10 cents or more per single 6/o bead. They look GREAT with my artifacts, though. I bought some from York Beads, but I just found out they closed shop last year.

I thought about using acrylic paint, but it could easily wear/wash off.

Since it's just a coating on the beads, I'm curious if adding a matte coating like this could be done with a micro torch? "Frit" comes to mind, but I'm not sure why!

I have tons of plain Czech glass beads that I'd love to experiment with.

Is this a ridiculous idea, or doable??
