Boeing. It's a sputtering process and yes the glass is charged electrically to receive the sputter. Howard always referred to the "Cryo" chamber when we talked about it.

Larry Bell was really the first artist to apply it to glass and that was back in the '80's. Coatings by Sandburg really became the big kid on the block having set up five slot pedestal machines. It's a slow process, taking about three hours to coat a sheet so five pedestal machines were critical but they cost 10K each. and then it depended on whether you wanted an outer coating of quartz which did a great job of keeping the coating from burning off.
