With multiple firings, I created these 19″x1/4″ glass disks. Now I just placed them in the kiln on the molds which I prepared yesterday.
I’ll be heating them slower than normal as they are thick.
(200F/hr to 1180F) ( Hold < 1hr)(Cooling AFAP to 900F) (Hold 3 hr)(50F/hr to 700)
I have a couple of concerns: 1) Because of the sower rate, I might cause devitrification (scummy glass) 2) the edges of the glass disks extend a tiny bit past the edge of the molds. Glass expands more than ceramic, so the edges might catch on the mold.
