I was just having a great chat with Google's AI online, about ancient Egyptian quarrying techniques. I asked specifically about the use of natron. Google said it could work for that purpose, but it thought the logistics didn't make sense because it wasn't necessary.
Natron lowers the melting point of silicates making it valuable in the ceramic and glass industry, but the amount of penetration achievable using natron to etch out a stone at a quarry would be around 2mm before the slurry of natron water needed to be scraped and reapplied under a trenched woodfire. The woodfire alone would have a similar effect on crumbling the stone without adding the natron.
While natron lowers the melting point and can soften the silica particles in granite, it doesn't melt it into a pourable liquid. A hot woodfire by itself would undermine the micro bonds of the stone particles all on its own.
Apparently, archeologists have documented the use of fire in this way, by analyzing the stone to discover the wood coal, and through hieroglyphic documentation of the processes. Stone-on-stone pounding, as well as bronze tool scraping of the flaky results are believed to be reasonably achievable under these fire-based techniques.
