I think you are confusing polyethylene glycol quenchant with ethylene glycol antifreeze.  These are very different chemicals.  The preferred molecular weight of polyethylene glycol for metal quenching is about 10000l  The molecular weight of ethylene glycol in antifreeze is 62.07.  Polyamory sounds like amory, but they are also very different :)  Also, transforming the latter into the former is difficult.  Synthesis of the polymer is performed with ethylene oxide, which is very different stuff.  This reaction is not for the faint of heart.


It is recommended to start with simpler non-toxic polymers that are easier to acquire.  It might be worth experimenting with some easily prepared food based polymers.  I have not heard anything about cornstarch mixtures, but they seem to have interesting properties.  I have heard that psyllium seed extract can succesfully used as the foundation of a polymer quenchant.  Carrying out polymer syntheses in the blacksmith shop is not for the inexperienced, especially reactions that are subject to runaway polymerization.

The knife has some hammer marks, but it will make a good hunter. I raised it to bright red heat and oil quenched. I "soaked" in oven heat of 425 degrees for 1.5 hrs and cooled in water. I then heated the back of blade to blue on electric stove and let the edge remain cool with no color run.
