As this is the beginners level tutorial on "Metallurgy", this essay is only about "HOW TO HARDEN STEEL". I will limit my text writing, as photos speak better than words.
This is my mini-torch and it works very well, regardless of its operating size.
Heat the tip of the burnisher.
The hot area has to work itself halfway down the shaft.
KEEP THE FLAME AIMED CONSTANTLY AT YOUR NEXT WORKING AREA.
We want the tip to be well softened by the flame.
Maintain the heat and move the flame downward.
Don't let the flame wander away from the tip. It has to remain HOT.
When the burnisher is 'RED hot', drop it into cold water. This process hardens the steel, again! You can see the bubbling of the water, as the steel is rapidly cooling.
You have succesfully hardened your Burnisher.
Your 'refurbished & hardened' Bead Burnisher is now ready for more weeks & months of continual use.
