AnneAling Thick SlAbS: This annealing chart has been formulated for use with bullseye clear glass. It is derived from corning’s method as shown in mclellan and shand.* It is based on a flat slab of uniform thickness that is set up in such a fashion that it can cool equally from top and bottom. Annealing Thick Slabs (Fahrenheit, rates in degrees per hour) 20190627_EFL How to Read This Chart In 5 Steps 1.Choose a chart from either side of this form based on your preference for units used to express cooling times: Rates in Degrees Per Hour or Rates in Time to Temperature. 2.Calculate the final post-fired thickness of your slab. Now you can proudly display Bullseye's indispensable annealing chart for thick slabs on your studio wall. Great for those times your TechBook isn't handy—and much easier than trying to read your T-shirt in a mirror. Chart measures 24 x 32. But whenever the TechBook isn't handy, you can always glance up at Bullseye's indispensable annealing thick slabs wall chart. New and improved, it comes in both rates of degrees per hour and rates in time to temperature. (You get both!) Post the one you prefer proudly on your studio wall. Chart measures 18 x 24 inches. Anneal thick slabs at 900 degrees F. As of June 2009, Bullseye has changed its chart for annealing thick slabs. Specifically, the recommended anneal soak temperature has been lowered from 960°F/516°C to 900°F/482°C. Anneal thick slabs at 900 degrees. As of June 2009, Bullseye has changed its chart for annealing thick slabs. Specifically, the recommended anneal soak temperature has been lowered from 960°F/516°C to 900°F/482°C.

5 Oct 2018 The slab was taken to 1490F for 30 minutes. I used John Groth's recommended 5 /8" ramp and anneal but slowed further to the Bullseye 3/4" annealing times. However the polarized view shows some tension at the thicker ends so I F again for 10 minutes and cooled following the Bullseye 1.5" schedule.
this TipSheet refers specifically to work done by the Bullseye. Research and Education Department more information on annealing cycles, see “Annealing. Chart for Thick Slabs” under the Education tab at www. bullseyeglass.com.) Figure 6: 22 Mar 2019 At some point I'll find a better place on this site to put this chart, but for now here it is. Set up glass Annealing Thick Slabs. June 17 Bullseye's reference for firing thick glass is must-have technical information. » 1; 2 · 3. Two useful thick glass firing schedule sites are Harrach Glass and Bullseye annealing thick slabs. The following photographs show two examples of fused An example of a firing schedule for Bullseye glass, 1/4" thick would be: 300 dph to 1000 - hold 40 min 600 dph 1480 - hold 10 min. AFAP to 900 - anneal as usual Paradoxically, aperture pours (pot melts) and high fire slabs, which are often 1 May 2018 The annealing times come from Bullseye's schedule for thick glass. I have yet to have a slab break or vessel break from failure to heat 5 Oct 2018 The slab was taken to 1490F for 30 minutes.
