Hi,
Hreres a few pictures of some trophies done today on an installation.

Some very nice work Si

Very nice, but where is the proof glass is a liquid

[SimonMallas]

Cheers Dave, and Morning Phil
Wow what way to start the day half laughing an half chocking, on my corn flakes! Nice one Phil : ) that could be a long thread! lol sure Dave could give use the proper answer : ) I only know that your windows get thinner at the top and fatter at the bottom over time (sounds like I'm describing me!!!!) think the clever term for what glass is is anamorphic??
Cheers Simon

Nice work!

Bit of interesting info on glass

More research is still required on that front, I mean proof, because its all basically assumptions, and yes, there is evidence in the way of glass panes being thicker toward the bottom, however, this is all apparently float glass and produced decades upon decades ago. in which case, did the installers know that the thicker part of the glass should be installed at the bottom, for strength. I read an article in new scientist about it, and the consensus was, there is no proof yet. Its just a theory still! They could rig up experiments to prove or disprove, but no one has done so yet!

Thats what I meant by 'proof'

Hi Phil,
Ya its a real fascinating material which ever way you look through it : ) not sure I'm feeling the old float glass thing. Floats only been around since 1950ish. Prior to that it was pretty much rolled, streched, prodded, poked and grinded (if you were rich) if you take a look at any old town hall, library or church you maybe able to see it for yourself, not the stained glass, but any bigger clear pane ( normally full of floors, swirls and bubbles ) in some cases it can even be bellying over the frame. I'm not expert but it's there if you look for it : ) and what about the way it holds BEER : ) nothing does it better : )
Cheers Simon

As an anamorphic, glass has several properties defined by the laws of physics, crystalline length and structure is what decides it's qualified properties within certain parameters (The same way the properties of all elements and materials is defined)

It's these very properties that define it's suitability for any given process (of course depending on manufacturing methods) but it's physical properties mean that shift will take place over time as the structure is inside of the requirement of the main forces it is subject to over time.

I can post the long version if anybody needs it

best wishes

Interesting read.

Here is another about the myth of windows - the statement about Egyptian glass in interesting (I love myths me)
