A bead in progress on the "Sarah" furnace. Note the thermometer reading 1167 Celcius. Note the angle of the mandrel and the way the glass has flowed downhill. This will need to be corrected or the bead will be more likely to break coming off the mandrel due to the thin glass at the front of the mandrel.
