I always hardened my blades, let them cool to room temp., then placed them in my wife's kitchen oven for 2 hrs.
at 300 degrees. I turned the Paragon furnace off so it would cool to room temp.
The next day, I placed them in my Paragon and brought it up to tempering temp. for the time required.
We called the kitchen oven step a "flash Quench". It prevents stress cracks due to rapid temp.changes.
