So here’s the parts list:
$29 for the stovetop
$12 for the gas line
$18 for the ceramic stock pot
$4 for the thermometer
$15 for the lye
$6 for the Sodium Nitrate
$16 for the face mask
$6 for heavy rubber gloves
$3 for distilled water
$3 for vinegar.

So under $120 for the whole setup. Less than the cost of one decent bluing job. And this should last for four or five guns. And the comestables consist of the lye and the sodium nitrate.

Damn, I’m really pleased I did this.
