TAG 104 is a range of coe104 glass from Oregon, USA. These reactive glasses may be struck or reduced, and are compatible with other 104 glasses such as Effetre and CiM. Trautman Art Glass, the manufacturer, recommends annealing at 507C. We anneal them using the same schedule as for our other soft glasses. These rods are available singly, or in packs of 1/4Lb, which is 5-6 rods. Rods are 30cm long, and 4-6mm in diameter. Our TAG Variety Pack contains 1 rod of each production colour, 14 rods in all!
