The quality of a glass water pipe can be measured in many different ways. However, the type of glass used is at the top of the list. Here much can be won, but also lost. This starts with shock sensitivity, goes beyond the thickness of the glass and
does not necessarily end with the type of production. At this point your worth knowing and instructive all around the topic Bonglas learns on which professionals swear and in which places one should let special caution prevail. Let's go into the world of glass technology!
Type of glass
You don't have to be very imaginative to recognize the relationship between glass bongs and laboratory equipment. And indeed, many manufacturers of water pipes also manufacture glasses and flasks for chemical processes. Also in this respect one thing is important: the heat resistance or the coefficient of thermal expansion (which describes how strongly the glass expands with temperature fluctuations - which may lead to cracking). The glass of choice here is
borosilicate, which has proven to be ideal for these purposes. However, this is only the beginning of the flagpole, it goes even better:
Duran glass from Schott
Normal Borosilkat is already very resistant, for the normal (also somewhat rustikalen) handling with the pipe it is recommended however still a shovel on it to put. Schott Duranglass is now the glass of choice for many renowned glassblowers and this is also reflected in the service life of the pipe. Heat-resistant and blessed with low thermal expansion, Duranglass makes longtime companions out of bongs who (almost) do everything.
