Glass.

[Saluki]

It's a liquid. We learned this at school and I was told again when I worked, briefly, at a windows factory.

I bet that was a pane?

You could say it was a pane in the glass.

I like this. Best full

Ugh no, those old-fashioned jugs make me think of flat warm overpriced beer served in poncy London pubs.

Straight sides every time and a clear glass to allow you to see the beauty of the amber liquid.

I nipped out, so missed the last part of the programme. I can see traces of blood in the speaker grille of my wireless, so I think it got quite nasty at the end.

Slow moving solid, a bit like @rich p.

As in semi solid cylinder?

 

[classic33]

Neither.

Before it becomes glass, it is solid, then melted , then becomes glass. The same could be said with metals.

 

[Saluki]

No it's not.

Heigh ho. I shall mention this when I next work for a windows company (not likely around here, thank God)

Glass is among the most magical and beautiful substances around, and glass blowers and artists are nothing short of magicians and alchemists.

This is pretty amazing:

Depends on the temperature doesn't it? Is ice a solid or liquid? Glass can be either, and even a gas if the temperature is high enough. In my other life I made studio ceramics and it was quite magical to peer through the spyhole of a kiln at approaching 1300"C and see molten glaze shining in the almost white heat. If the kiln is too hot for the glaze it can run, and pool at the bottom of the pot, sticking it permanently to the kiln shelf on cooling.

Amorphous solid. At standard temps and pressures.

Glass flows/slumps over time. So

Both. I read somewhere, that over a period of decades, the glass in your windows will thicken slightly at the bottom, as the glass errr slumps ( the best way i can explain it) as glass never solidifies completely.

Lead does the same.

 

[FishFright]

Glass doesn't flow or slump over time. So

Lead does .

FTFY and @User

Being a scientist must be such a frustrating business

I wish glass did display fluid behaviour at STP. The majority of my life is spent working out ways to make glass behave in strange ways. It takes a whole lot of effort to get it to behave like a fluid.
