I was talking to an old business associate who is selling to Chinese sapphire furnace manufacturers. The furnace that GT sold back in 2012 has not changed that much. There was a lot of "dead"space in the furnace and by using larger crucibles they could get larger boules. The challenge was in scaling the process.
Theory only gets you about 1/3 to the goal. The rest is trial and error...which takes time and GT grossly underestimated the amount required ...or ignored the technical staff's input.
