NS-013 Amber/Purple: Of the striking colours in the borosilicate palette the Amber/purples are some of the most exciting. NS-013 is the first in a series of five Amber/Purple colours. It is well suited for sculpture and moderately thin blown work.
This piece of Northstar Borosilicate coloured tube is 510mm long. Because it is hand drawn the tube is 25mm o.d with a 4mm wall at one end and 28mm o.d with a 5mm wall at the other.
