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.

Looks like the form of clock was both time spent speaking out prayers and verses, probably to support a skilful eye for colour checking. We may see that both 'techniques' were (also) used in Toledo, as written by various authors.
The synopsis
The fifteenth, sixteenth and seventeenth centuries marked the greatest splendor of this industry and it is when the Guild of Sword smiths began to be constituted, artisans from all over Europe and even from the East came to Toledo to learn from those artisans the “secrets” of the manufacture of the inimitable blades, that raised the name of Toledo and its Tagus to a height that no other city has been able to reach through the centuries.
The fame of the old Toledo steels lies in the mastery with which some craftsmen handled the tempering, without any technical knowledge or instrument capable of measuring, even remotely, the appropriate temperatures for said treatment. The temperature was known by the color of the red-hot steel and the time of immersion in the water, through prayers or verses alluding to the trade. The people attributed this quality of the temple to the waters of the Tagus river in which the swords were tempered.
... and the unavoidable legend.
Legend has it that the first tempered steels were developed by mere chance in Toledo, Spain, where the royal armory was concentrated in the middle ages. Swords, armor and metal parts in general were manufactured there. Through a mixture of cruelty and servility, the royal blacksmith came up with the idea of skewering a prisoner of war (probably a "Moor" or sympathizer) captured in the wars against Arab domination. No need to explain that this cruelty made the blade of the sword to be heated "to red" to commit the "symbolic act" "ritual death" or "baptism of blood" and the result was overwhelming, the sword was hardened or TEMPERED using the body of a man as a refrigerant for the process, in front of the discovery, The surprise and after the surprise, all the nobles ordered their Toledo sword, so they were left without slaves to sacrifice and by dire analogy and contempt for the enemy, the slaves were replaced by pigs that died in a tempered process of swords until someone thought of that that of having to kill someone or an animal to temper the steel could be a superstition and they tried to do it with water, oil, with the same results and so it is until now on the west side of the planet.
