Canola Oil

I also think it mentioned less scale to remove, not sure though.

I am curious about 'rapeseed oil' as against canola oil????????? anyone know.
 
rapeseed is a european term for canola. As said, heat to 120-130F and off you go. I use it with O1 tool steel and have had no issues. yes i know commercial quench oil may be better, but I can get canola at the corner store for $5 a gallon and it is not hazmat.
