<HTML>For those still following the faience discussion...

Archae Solenhofen (and Arch, I'm sorry if I misspell your name anywhere.... okay?) has posted a VERY nice analysis on his site regarding the cutting of both limestone and granite.

And guess what he turned up when he found that Stocks had cut granite with a copper saw? (See if any of this looks topical)

*************
As sawing proceeded during the dry sand test the tailings, containing both copper and rock powder (both the granite and abrasive), were easily collected. ... Stocks (1989; 1997) proposes that the tailings of the cutting process could be used in the <b>manufacturing of a faience, from a water-based paste of calcite derived tailings (from limestone and travertine coring) and sodium bicarbonate (natron). As well, blue glazes can be produced from diorite and granite tailings. Both the blue glazes and the faience produced by Stocks resemble in appearance those common to the ancient Egyptian's. </b>Stocks (1993) suggests that tailings could also be used as a polishing abrasive because of its 0.5-5 micron grain size, and also as a abrasive for the drilling of beads. A grain size of 5 microns (0.0002") is ideal for lapping gloss finishes on rock surfaces, since the transition from frosted to semigloss lapidary finishes occurs with abrasives about 15 micron in diameter, and high quality lapidary polishes are generally done today with abrasive grain size of 6 (0.00025") to 0.5 microns (0.00002") (Craig & Vaughan 1981).
*************

What do you know... a crossover from the lapidary cutting of the blocks that ALSO explains the existence of faience... without geopolymers.

These two are just as interlinked as they are in the geopolymer theory.

Fascinating.
