Press-Blow Machineswide-mouth ware such as mason jars, tumblers, milk bottles, etc. The process is efficient and permits the fabrication of light weight bottles of uniform wall thickness. The beginnings of this method were in the period of development of semiautomatics. The process later was taken over by fully automa

Drawing of Tubes and Rods are now extensively made by machine. The variety of tubes and rods required has preserved the manual process for special types and low quantities in spite of the development of efficient tube and rod drawing machines. For this reason the description of the most important mechanical drawing processe

Surface tension also plays a significant part in free forming. To a limited extent, expansivity is of concern. This is particularly so in the fabrication of hollow ware where sharp loca

With rising temperature the viscosity of glass decreases continuously. A viscosity range from 10. to 10. corresponds to a temperature range from 700 to 1400 °C; that is the viscosity changes ove
