Hi Guys. Im tempering My blade and its been in the oven for 1 hour. It got a Nice light straw but scattered across the blade it got weird bright purple/blue colours.. It doesnt really look like it tempered different than the rest, it look more like som crazy oxidation i dont undstand.
What cold be the problem? AM I screwed and need to redo the ht? Dont got a pictures rigt now.
I did 3 normalization cycles. One above critical, one just below and one deep cherry red. Then quench in 130 f canonla oil like i use to. It hardened real Nice.
