The annealing method we used to use was to stand the brass in a pan of water so that they are submerged to just below shoulder height. Then heat each with a torch and when it is hot, use the torch to tip it over. Properly annealed brass will go a long time unless you are really working the neck/shoulder area hard.
This is the method i've always used too...
Brass is made up of copper and tin, and annealing it after several fireings makes it last a lot longer. There's probably several ways to do it, but this way that's been workingfor me for the last 40+ years, so i'll stick with it.
