The site of the Jamestown glass works was described by Smith and mentioned by writer William Strachey. [29] Ruins were discovered in 1931, leading to the belief that the Jamestown glass works was located about one mile (1.6 km) from Jamestown at a place now known as Glass House Point. [30]
Glass tubes are produced in various types of glass and in diameters ranging from a few millimeters to several centimeters. In most production processes, an "infinitely long" glass tube is drawn directly from the melt, from which approximately 1.5 m long pieces are chopped off after passing a roller track up to the drawing machine.
Tube sinking, also known as free tube drawing, reduces the diameter of the tube without a mandrel inside the tube. The inner diameter is determined by the inner and outer diameter of the stock tube, the outer diameter of the final product, the length of the die landing, the amount of back tension, and the friction between the tube and the die.
