English blades

The issue I was opening for debate is that Wootz may not have been tempered.
This seems like a contradiction to everything we have come to understand about blade forging.
Are there any blacksmiths or metallurgists out there?
I think if it was to be tempered and quenched then the temperature will have had to have been very accurately controlled, so some form of clock was a must, or great accuracy in the colour of the metal, which I thought was how the Japanese did it.
