Thanks for answering, it was strange when I took a 2 day knife making class with 1084 and there was no preheat in the has forge.

My teacher has always told me to slowly heat hi carbon steels by resting steel near heat to a black height with slight red glow before putting steel withing heat source, for coke forges. Alternatively, you can put steel within the gas forge while starting the gas forge. My question is with regards to gas forges, is there risk of micro fractures if inserting the hi carbon steel immeaditly within the forge that is already at desired temp?
