If you ask ten lampworkers for annealing schedule you will most likely get ten different answers. In my case, the annealing schedule is different than the one listed in this thread and yet has not failed even with marbles.

Ramp up times and annealing temperatures are dependent on the thickness of the material being annealed. Thus, using the charts in "Contemporary Lampworking" will provide the needed data for setting up your kiln's ramp controller.
