Crazy idea for bell...

[pyrolyse]

Could you make a single bell system looking something like this:



But with the bell being made entirely or partially of glass?!

Would it be feasible?

Glass isn't a good conductor, not much heat is extracted and so most of it will be gone to warm the birds. And, since there's a little bit of soot produced during every start up most of the bell will be black inside.

Partially glass, a window to look into the bell, could be done, preferably in the hottest area. And constructed as double glazing so the soot would burn off easily.

The idea came to me in a discussion about bells and especially the oil drum typically used in conjunction with the heatriser. The oil drum is describes as ideal because the thin metal quickly dissipates the heat and therefore creates a big difference between the extreme heat in the heatriser and relatively cooler enviroment along the sides of the drum. Glass also quickly dissipates heat, i.e why they are used in most newer woodstoves to give quick radiating heat. Doesn´ t glass in the application have almost the same attributes as the oil drum?

Glass is by no means the same heat conductor as brick, let alone steel. Where do you read glass is quickly dissipating heat?
