If you haven't noticed yet, dichro is a hot commodity, anything new that hasn't been done by someone else or even thought off, is something to jump on. You can make a killing at it. but if you are doing this for beaders, it would have to be awfully tiny, but if you did it on 2"x2" to whatever size you were comfortable with you may get a better market with the glass fusers, for tiles, bowls, plates, vases, panels and such, and don't forget about the COE issue, there is a lot of fusers that use COE 90 - 96 or 104.
. Its a very big and vague market, depending on how you get into the marketing aspect, you tube, etsy and so forth. If you go ahead with this let me know I will be your first customer.
