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.
Glass balance spring in watches have been tried before

Claims to be an all glass clock

Appears to have a metal weight. [scad mientist, Jun 24 2020]
Flexible Glass

The flexible glass bit is about 7 minutes in on the video. [xenzag, Jun 25 2020]

If there are weights, what is the spring for? |
|
| |
This made me say, "but why?" [+] |

//a type of special type of glass capable of flexing enough

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

Thank you, [bs]; bun awarded. |
|
| |
//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. |
|
| |
The chimes are going to be crystal clear, |
|

[kdf] The more current link you posted has bigger pictures,
and it looks to me like this has metal pins on the
escapement. |
|
| |
Technically an hourglass 'is' an all glass clock... |
|
| |
...I'll just get my coat again. |

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. |

| |
Yes but what is the glass spring actually for? |
|
| |
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. |
|
| |
OK so what are the weights for? |
|
| |
Falling on your head when you climb under it to
collect the humbug you dropped. |
|
| |
Glass weights are not optimal for that, they might fracture. |
