Glasswork

This is a page for dumping stuff related to the glasswork talk. I have not made a presentation yet, but I intend for it to have some of the following information

Things that don't work good:

• score all around the bottle**
  • I have seen this in lots of places. This is almost never a good idea, since it is difficult to match the line to itself. Some seem to have had success with a jig.
• saw
  • You can do this with a tile saw maybe, since it will keep everything cool with the water flow. Expensive setup (maybe good for a makerspace)
• flame polishing
  • While this is probably the best,and certainly the most professional means to accomplish this, you really need to anneal glass after flame polishing. While I don't have any personal experience with this, I have it on good authority. An annealing furnace might be a good thing for a makerspace to have. We could totally attract the glass community with that...
• hot wire
  • A nichrome wire that is wrapped around the bottle, and suitably attached to some voltage source can work. We should try this, it sounds fun.
• extra low tech
  • tying a string, alcohol, using a candle, setting it on fire, using ice, cold water, etc.. - come on, people. we can do better than that
