Viscosity of Glass

i read your link, but i'm not sure if the information gave a diffinitive answer. as i understand the article, it's the additives that's used in making glass that changes the properties? romans seemed to have understood that for millinums, but did other societies "non-roman"?

Please feel free to misinterpret the information however you choose.

i gave you a g.a

Thanks!

Don't know who your "scientist" is, but basically the glass is non-uniform in thickness because of the way it was made back then. Scientists with far more time on their hands than I have have studied this "phenomena" and determined that roughly 25% of the panes have a thicker bottom, while roughly 25% are thicker on the top, etc.; I hope that you can see the pattern evolving here.

If you want to see where the above comes from, and read some real science, check out this link:

i never claimed he was a scientist. he did.

i never inferred that he was a scientist.

By including "scientist" in the OP's opening remarks, he most definitely "inferred" (hinted or suggested through print) that whatever "journal of science" he was reading referenced his source as a "scientist".

I suppose if he were posting from the shiny side of Mercury glass would appear to be a llquid. Damn near everything can turn liquid at some point depending on the pressure and/or temperature.

Just looking at "glass" (which has a multitude of chemical compositions) and saying it's viscous would be like looking at obsidian (nature's glass) and saying the same thing.

Viscosity for everyone!

i wrote "scientist?"

Since we are checking grammar and spelling, it's "implied", in this case.

"Inferred" is how we intrepret what someone says to us.

lyn, when i put a "?" mark as in "scientist?" , i'm inferring that i have my doubts about his credentials.

No, you are implying that you have doubts.

sorry RAMConsultant, a little sarcasm "scientist?" never hurts. i had my doubts too. he just inferred that he was.

glass moves thats placed on an edge. gravity will pull on the glass. super slow but it's true

okay this one bugged me so I did some digging. now I'm thinking I bought into an old myth! so much for "internet facts"...I'll trust what I read from MIT...glass id a solid...old windows were routinely installed with the heavier bias side down as a practice.......that explanation works for me
