Your fining temperature is 2350°F or 300°F above your working temperature.
After the last charge raise the furnace temperature to about 2400°F (1315°C). We believe that you should not get over 2450°F. Hold at 2400-2450°F for about 8 hours. To check the progress of your melt take small gathers and look at the bubbles. When the bubbles are all larger than pinheads, you can turn the temperature down to squeeze the bubbles out. Each furnace will function slightly differently. One furnace will squeeze OK if you turn down to just your working temperature, another may need to be turned down 50-100 degrees below working temperature. A good general rule is that your squeezing temperature is 100° below your working temperature, in this case 1950°F. This will also take about 8 hours.
