Modern jet channeling uses flames at roughly 3,000°F (about 1,650°C) to cut granite, exploiting quartz-bearing stone's thermal properties to cause thermal spalling. Channels can be cut about 6 metres deep. The video compares the 40 cm-wide Aswan scoop marks with typical 10 cm channels and argues that ancient Egyptians may have used an enlarged, torch-like flame tool. Diamond wire sawing has replaced or supplemented jet channeling in some U.S. quarries, although jet channeling remains prevalent at Elberton.
Jet Channeling and the Video's Aswan Scoop-Mark Theory

📍 Aswan, Quarry (north)🌍 Show on the globe
Key facts
- Jet-channeling flames burn at approximately 3,000°F (about 1,650°C), not 2,500–3,000°C.
- Jet burner channeling remains the prevailing method at Elberton, so saying it was replaced throughout the United States by diamond wire sawing is too broad.
- The claim that an enlarged flame tool produced the Aswan scoop marks is the video presenter's hypothesis, not an established finding attributed to researchers.
