ok an example. lets say that you do not batch anneal, you anneal and go. and lets say you are making focal beads that are 1/2 in diameter and 1.5 inches in length. the important dimension is the smallest dimension ,1/2 inch (line 3 of the chart). lets say you made your focal bead out of moretti glass. the chart says that you need to let the beads soak at 930F for 30 minutes after you put your last bead into the annealer. then you need to ramp down to 850F in 9 minutes or more (there is no maximum, if you want to do it in hours that is ok, but not any faster than 9 minutes). then let it soak for 4 minutes or more, and then ramp down to room temperature. if your are making 1.25 inch thick marbles, use line 6 from the chart. if you are using bullseye or boro, use the temperatures shown at the bottom of the chart. remember, these are minimum times, you can make any step longer.
now if you batch anneal, you need to follow the steps for T1 and T2. if you anneal and go, you start at T3.
