Some folks like togo to 550 F. You  must remember that the color may not penetrate far into the stone. Carnelian beads in India were traditionally "burned" 5 times starting with the rough and ending with the burning of the finished bead or cab. The early burnings were not for color but to slightly soften the rough  at each of the preforming stages. They have made carnelian beads for over 3,000 years and have made untold amounts. A lot of people soak the carnelian slabs in muriatic acid with iron nails in it for a month to add more iron to the quite porous agate. The
Germans were very good at this and they dried the agates in a warm dry environment for 3 months before burning them  to red.
