622066 TAG Syzygy Borosilicate Glass Rods.Size: Diameter 5-7mm, length 20", weight per rod .07 lb, approximately 12-15 rods per pound. There is a quarter pound minimum per color. All TAG rods are first quality.

Syzygy is a florescent light reactive (FLR) glass that is a light golden yellow under sunlight and most artificial light, and turns a vibrant transparent pink under florescent light.  Syzygy, pronounced "siz-i-jee", is an astronomical term for the alignment of three celestial bodies.  It is similar to TAG's Red Elvis in workability, is stable, and is not reactive to flame's atmosphere.  Paul's formula has a very strong FLR reaction, and the sudden color change is sure to shock and awe!
                                
ATTENTION: Due to the weight and length of the rods you may receive .30 pound vs .25 pound (as an example) when ordering. This will cause the cost to rise and the amount you expect to pay for your glass may change.

If this is a problem, please let us know and we will “underweigh” your glass. This means instead of .25 pound you may receive .20 to .22 pound. Please be aware that it is almost impossible to pull exactly .25 pound. We will always try our best to get as close as possible to the weight that is ordered, but due to the factors stated, these weights may substantially increase the total cost of your order.
