A single rod of this reactive glass.
Pronounced “TOSS-ko”, this glass is named for the town in Mexico renowned for combining silver and turquoise. A transparent reactive glass that produces a shiny mylar surface when reduced without oxygen, or gives a mottled oil-spot look when reduced lightly with some oxy in the mix, particularly over black or other dark colours. Alone, Taxco can reduce to a silvery sheen over the blue-green base. Heavy reduction gives white clouds with copper and terra cotta patches. Taxco likes to be reduced when still barely glowing a light orange – but too hot and reduction burns off, and too cool it won’t stick in the kiln. If it’s a tad boily, turn up the gas & work higher in the fire.
