For glassblowing, you usually heat your glass up in a furnace before blowing through your tube into it. This
furnace usually consumes a lot of fuel and, as I understand it, it needs to be kept hot all the time. I don't know
why, but this means it's expensive to run.
Glass, when it's already red-hot,
absorbs microwaves [1]. Microwave heating is also very efficient compared to
heating by flames, at least disregarding the magnetron and its driver circuitry. So, an alternative glassblowing
furnace would be a microwave-based one, with a burner only to heat the glass until it's hot enough to absorb
microwaves.
This could be more suitable for places that only do glassblowing once in a while rather than every day.

This is quite an excellent idea. Possible issues: (a) uniformity
- I think the point of a furnace is that it heats the glass
evenly, so that it deforms evenly when you blow it. (b)
leakage - you need to be able to get the glass in and out
easily while attached to the blowpipe, without getting
yourself microwaved. But definitely [+]. |
