Heating curve Slow Cool
0 – 105°C in 2.5 hours
105°C – 1095°C in 5.5 hours
1095°C – 1205°C IN 0.5 hours + 15 minutes shuttling
1205°C – 1176°C in 0.5 hours + 15 minutes shuttling

It is important to note that you must adapt this schedule for your own furnace and firing.
Every furnace is different, so there is no schedule that works for every firing.
At least the tip of your self-supporting cone 5 should be flush with the base,
and the tip of the cone 6 should not touch the board.
