Does Borax migrate?
Hi,
I was doing a bunch of compatability tests with regular spectrum (1" squares on clear fusing strips, brought to 1550 for 10 minutes) and I decided to do 2 tests at once by seeing which would require borax to prevent devit. So I put the solution on half of each square. When I took this pieces out of the kiln, they were all bright & shiny -- no devit in sight. I've run tests on a few of these same glasses before and have gotten devit, so I know that isn't the issue. I'm trying to figure out what happened here -- my current guess is that the borax solution migrated around to cover the entire piece. Does that make sense?
Thanks,
Michelle

A few days ago I alluded to this, and I've seen it too. Physicist friend of mine has seen crystalline phenomenon that mimics this, but in a lab using giant silicone crystals. I wonder if it has something to do with nucleation, there needing to be a critical mass of "seed" contaminants for crystal formation to occur, and once it does allows it to perpetuate easily. If you put enough borax on to prevent it from reaching that "activation point", it prevents crystal formation? Or maybe it's magic.

Interesting. I recently heard that for the first time small numbers of borax, including juveniles, have been seen mixed in with the annual caribou migration.

I totally agree. thin, thick, brushed, sprayed, wet, dried......Tony Serviente wrote:Rodney-In my experience, you can have tremendous variation in the strength of the solution and still get good results. It is very forgiving, as I have found by being in a hurry and not doing it "by the book".
