Glass Cyclones

Pictured on the right is a custom jacketed glass cyclone viewed under polarized light, before being annealed. The colors reveal various states of compression and tension that result from the heat-cycling which the glass goes through in manufacture. These stresses are "relieved" in the annealing process.The internal structure is nicely revealed in the polarized light, something that is a little tricky to show in regular photography. Here, the cyclone is viewed between crossed polarizers.

We make a lot of glass cyclones, typically for separation of spray dried powders. Glass allows for direct observation of the cyclonic/separation process.
