Micro Torch

Heating cases can reverse work-hardening completely and make brass flexible and able to reform. This process of heating softens the brass and is called annealing;
During annealing the accumulated stress in the micro structure of the brass is cancelled and the brass brought back to its natural condition;
We use a pencil flame because, a wider flame would heat to wide an area on the case and a wider flame could also heat the Tempilaq directly and give a false reading;
I always anneal all new cases to ensure they are uniform and constant;
For the sake of uniformity, I anneal fired cases each and every time I reload them.
