Does anyone know why my blades go red when I normalize them

Recommended Posts

My blades get this reddish scale when I am normalizing them. The harden perfectly but I'm curious to know why and if I'm normalizing wrong and for this reason they develop the red. 

 

Thanks!

Don't know the science behind it, but I believe it's a result of the H2O that is a bi-product of burning propane.  I get it in a lot in my cooler burning forge and only a little in my hottest.  Weather and humidity seems to be part of it.

Exactly.  It's just humidity in the forge atmosphere turning the scale from black iron oxide to red iron oxide.

No, it's as Alan said, no worry.  I was just exercising my wit :-)
