Abstract
Improvements in the procedures to obtain gauges essentially by subjecting a cylindrical glass tube closed at one end to a process comprising, introducing inside it a solid hard body of conical shape, causing on the whole a external air pressure combined with sufficient heating to bring the glass to a state of sufficient viscosity to achieve its adaptation to the interior shape, by effect of the created external pressure.
