Thanks damascus,

You're really "in for it now"..

Now, a little clarification is needed. (at least for me) Please pretend that you're dealing with a thirteen-year-old that has only a basic understanding of the processes involved.

Ok, after you've brought the spring to cherry red and quenched it, you bury it in Silver Sand in order to draw the temper.

How are you heating the spring and sand? Torch, oven, or burner?

Is it coated with lard at this point?

How do you tell when the spring is at the correct temp?

Silver Sand appears to be mainly crushed quartz. I have bags of crushed quartz I use in my horticultural experiments, (part of a soilless potting mix) will this work?

Lastly, the inevitable question: Have any pictures?

Regards
Ken
