Discover the Hidden Stress of Materials with a DIY Polariscope

[@adl3gm]

The additional lens that you used in front of the polarizing film, what type of lens/filter is that?

[@petevenuti7355]

I was thinking about those high temperature superconductors that only work under high pressure... and thought, can you make them inside a Rupert's drop? How much compression is the inside of a Rupert's drop under anyway?

[@WheelerScientific]

I have no clue if that world work, but it would be interesting to try for sure. I don't know though if the drop can form with something in the way.

Awesome video!

[@WheelerScientific]

Glad you enjoyed it! My glassware kept breaking so I wanted to check the stress.

[@whatever9749]

Great video! Came here looking to learn for a material mechanics lab, but wasn't expecting this to be so cool!

Do the color bands mean anything specific for each color?

[@IunaIia]

Ohhh this works have been so useful to Nigel. To be able to see the stresses and destroy only the afflicted pieces of glasswear after the plasma experiments.

I just use the light from a LCD and my polarized sunglasses

Where do we see how to assemble it?

I'm very surprised and slightly unsettled by the amount of stress in the acrylic encased liquid chlorine ampoule! The term used for this technique in industry and engineering is "photoelastic imaging" btw. Any update on the neon filled mercury barometer light ampoules potentially for sale?

[@WheelerScientific]

Yeah, it’s because I let the resin harden a bit and pushed the ampoule in. Then poured the top resin layer. That as you can see caused a lot of stress. Unfortunately I haven’t found a supplier of neon for an actual reasonable price. I’m still looking, just waiting on the gas.

@@WheelerScientific 👍🏻👍🏻

[@Derederi]

​@@WheelerScientificisnt laser polarized? It can emit light through porous solids. Would it show the stress inside? If you have the equipment and laser, you could test a ceramic pot perhaps.

5:45 borosilicate glass is amorphous not crystalline

[@phonotical]

I've heard it called stress but I've always thought of it just as density changes, because you can heat it up and those patterns don't tend to change (in my experience) Explain the difference in molecular structure for liner polarisation and circular polarisation 😅😛 Think you can apply that to schlienien imaging?

[@Preinstallable]

Borosilicate glass is also used in glass cookware such as PYREX

[@BenjaminMarmoset]

Interesting...
