[TheForge] Harden & temper

[Paul Sperbeck]

The interesting thing aside from the quenching qualities or 'super 
quench' is that one of the ingredients is Basic I from Shaklee...

If you read the label you will find that the Basic I contains Sodium 
Hydroxide... our old friend lye... the nasty chemical that the super 
quench was developed to replace...

Kind of looks like the $2 can of lye was replaced by $25 a gallon lye

Guess I will stay with lye and safety glasses and a face shield.
