Glass Clock

clock made entirely from glass
  [vote for,

Glass Clock is made entirely from glass components. This is something not previously possible until the advent of precision water-jet technology to cut the cogwheels and other components with total accuracy.

I am confident that the power could be supplied with a spiral spring, and escape mechanism, linked to two glass weights secured via a glass chain. In the case of the spring, this would be made using a type of special type of glass capable of flexing enough to store and release the required energy.

I intend proposing the clock to Corning Glass so we will see what they say.

       If there are weights, what is the spring for?

       This made me say, "but why?" [+]

       Umm ... ?   

       Bun suspended, pending.

       Glass can be made into a spring, playing with a fiber optic will demonstrate that.

       Thank you, [bs]; bun awarded.
pertinax, Jun 24 2020

       I posted a link to Absolut Glass Clocks ... only to notice a moment later scad-mientist had posted a much earlier version from the wayback machine.
kdf, Jun 24 2020

       What [pert] said.   

       //special type of glass capable of flexing// Sounds a wee bit like a WIBN.   

       If my fairy night light that flies over the beds of the kids and lightly touches their heads, can't exist because I was unable to explain how it could work...well I got booed, let's just say.   

       Otherwise a temporary + for the idea which I like, and a - for the implementation, I'm afraid.

       [kdf] The more current link you posted has bigger pictures, and it looks to me like this has metal pins on the escapement.
scad mientist, Jun 24 2020

       "metal pins"
Yes, I thought so and also wondered about mention of ball bearings. A quick email to Absolut should settle the question, I'll let you know if they reply. But even The Glass Clock of Bad Schüschein (link) had a metal mainspring. I don't have a copy of Thief of Time at hand, but I think I remember a note from Pratchett somewhere that said he got the idea of a glass clock from a real life example.

       Technically an hourglass 'is' an all glass clock...   

       ...I'll just get my coat again.   

       "An hourglass 'is' an all glass clock"
Depends on how you regard the sand (link).

       Bun gladly awarded in the wake of [Pertinax] and [Bs]'s comments.

       //special type of glass capable of flexing// Look up Corning Willow Glass, which is a flexible type of glass. See link for one small example.
xenzag, Jun 25 2020

       Yes but what is the glass spring actually for?
pocmloc, Jun 25 2020

       A clock's no fun without at least one spring, and there are any number of functions to which it may be assigned. eg to provide the energy for a chiming hammer.
xenzag, Jun 25 2020

       OK so what are the weights for?
pocmloc, Jun 25 2020

       Falling on your head when you climb under it to collect the humbug you dropped.
xenzag, Jun 25 2020

       Glass weights are not optimal for that, they might fracture.
pocmloc, Jun 25 2020

       You win sir/madam, +
blissmiss, Jun 25 2020

       Neat video on willow glass. If it's purely for fun and art, I guess doesn't matter what other function the spring has.
