Hi Mat, Try these guys, they probably have a better handle on who has what for slumping. http://www.glassartguild.com/wordpress/ Quoting "Hutchings, Mat (H USA)" <mat.hutchings@siemens.com>:

General question here for any of you. Do you know of any digitally controlled kilns in Utah that are large enough to handle a 21" mirror blank? I am planning on slumping my blank and that would also require a re-annealling. This would require a kiln that is very accurately temperature controlled.

Thanks,

Mat

Matt, Contact Ceramatec in Salt Lake.  They had some big digitally controlled ovens years ago.  Unfortunately, I didn't really keep track of them, but they may still have equipment.
