Thank you for posting the results of the challenges and difficulties that you are having with this style. It will be helpful to other members. I will also forward it to our Research and Development staff. I am sorry that the glass is not the right fit for your commission. As I said above, it's fairly new, and we don't know everything about it yet.
Re the number of times you can fire the glass, I wouldn't worry too much about that with most glass styles, with the exception of cadmium-seleniums (red, yellow, and orange), and pinks made with gold. Most Bullseye glass can be fired a lot, and stay stable.
