SIZES: Typically, there are about 7 to 8 rods per pound, 5 to 6 mm in diameter and about one meter long (40" to 43"). Often some colors are only available in 4 to 5 mm or 6 to 7 mm diameters. Clear, T-004, is also available in 2 to 3 mm, 3 to 4 mm, 7 to 8 mm, 8 to 9 mm, 10 to 11 mm and 14 to 15 mm diameters. Stringers are 2 to 3 mm in diameter.

STRIKING COLORS: Striking colors are colors that change to their true color after the glass has been melted. Some of them are: T-069, T-072, T-076, P-258, S-456, O-532 and O-536. Note: O-532 strikes at a very low temperature. If O-532 stays white and does not turn to a soft pink, you are trying to strike it at too high a temperature. Some colors are not true striking colors, but can change while working them in the flame. P-254, for instance, can wash out and/or become matted if worked too hot or long. At cooler temperatures it can become mottled. Other colors can separate into lighter and darker areas. Some colors reduce, that is, develop rusty spots, black lattice or a metallic look. All of these effects can be desirable and are controllable with proper torch settings and lampworking techniques.
