need help to identify something found in archeological site in egypt

[kermiche_mgp]

hi all
i found under 3m after digging in an archeological site in egypt, 7 kilograms of this thing(in videos below), i need someone to help me identifying it plz;
when i heated it it turns black and a very unpleasable odor is smelt; it dont dissolve in water so it is not nitre and it dont make effervescence with vinegar so it is not natron.
thanks a lot for all

Natron?

Natron?

Good possibility since Natron contains small amounts of sodium chloride and sodium sulfate which would definitely give off a foul odor when smelted. Considering that it was found at a dig at an archaeological site in Egypt, it makes sense that it would be Natron. See link below.

saltpeter...nitre?

Just trying to be helpful, by providing factual info. That substance is definitely not saltpeter/nitre, because the finder says "when i heated it, it turn black." Having messed around with saltpeter as a young fool trying to make his own homemade gunpowder (for fireworks), I can testify that saltpeter does not turn black when heated. Its white crystalline granular appearance stays looking the same until it (suddenly and vigorously) ignites.

The only other thing that I can come up with is Tellurium (see link below as I believe this fits your description). If not Tellurium, then may be some type of precious metal that contains sulfides. I would recommend taking the substance to a Geological Department of a University to have it analyzed.
