TAG
TAG 33 is a coe33 coloured borosilicate glass from Oregon, USA. Trautman Art Glass, the manufacturer, recommends annealing at 566C. These rods are available 'singly' (approx. 25g of glass), or in packs of 110g. Rods are 20 - 30cm long, and 3-6mm in diameter, so the number of rods in a pack can vary. A set of working note can be downloaded here.
