Oh, for fuck's sake - SEMANTICS. Boro glass is not as sensitive to temperature change as soft glass, so annealing is not as necessary, from what I have read.
In the beadmaking world, kiln annealing is necessary, most of the time, depending on the size of the bead. It's debatable whether it's necessary for tiny beads. In fact, the whole issue is and has been debatable for decades.
It might be helpful to know what the OP meant by "annealing" - but in the beadmaking world, that generally refers to cooling the beads slowly IN A KILN to avoid internal stress in the glass and increase durability.
Maybe "flame annealing" means something different in the boro/sculpture/off mandrel world, but here, where most people are beadmakers, it's a misnomer.
