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
Things to try
- various grits of sandpaper
- So, tried 320, 220. Think we need to find something coarser that is wet/dry. Search has commenced
- the new turntables (with hard drive motors, possibly)
- Turntable works great with about 6V applied (to the 3v motor??? ummm...)
- nichrome wire
- etching cream
- Not sure whether this will turn up the desired results
- glass glue (Isaac - do you have any UV LED's left over from your project? I need to do some curing. if not, the sun will do)
- this is fantastic. Bought 2 UV LED's, and the sun works great too.
- Will be taking photos of the process for the slideshow.
Ideas for the future
- use the turntable to do sanding.
- Mike suggested sticking the bottle down and holding a sponge on it. I say tilt the turntable a little, give it holey walls, and have it pass in to a reservoir with a polishing slurry. set the bottle in, turn it on and walk away until its sanded. set up various grits, and voila
