I have a collection of thin tungsten cylinders if anyone is in the market!

Glassblowers use tungsten rods to pierce borosilicate glass. When you get tungsten and a piece of glass hot, you can push the tungsten through the glass fairly easily. Tungsten doesn’t get “wet” and stick to glass at these temperatures (~2000F), unlike other metals we use such as steel or brass. We tend to buy these at the welding store (arc welders use them as electrodes or something).
