Metals in glass are AWESOME!

I have a glass vase that changes color depending on lighting. Cool and beautiful effect, but what's the science behind it? In this video I examine it more closely and look into other color-changing glasses. It is beautiful!

This should be a preclude to teaching spectrometry. Would be perfect way to illustrate how we can identify what stars are composed of, or what the atmosphere of different planets are composed of.

[lukassarauskas]

It's so weird how metals have the ability to infuse things with colors while in certain states. Chemistry is trippy.

[Dukefazon]

"Hey, honey, have you seen my green beads? I don't know where I put them..."
"I don't know sweetie, I only found these purple ones" :D

[jameslatham]

Cool video! Never thought about the metals in glass.

[jesusgonzalez]

The reason that Cranberry glass, used in stainedglass windows/lamps, dishes, vases etc. is so expensive, is because of the precious metal (gold) used in making it.

[acr_master]

man that opening music tricked me into thinking im watching an SCP-illustrated video. good stuff!

[paulpardee]

This video is an example of why you're one of the best science channels on the internet today. Great video, man! And the photography during the montage was first rate, too. Gorgeous shots!

[ExaltedDuck]

wow, I work in an industry that deals with pigmentation so I've seen plenty of examples of metamerism but that demonstration at the beginning is one of the most impressive demonstrations I've seen of it. Usually, it's just something that looks a couple shades off in varied lighting, not entirely different colors.

[GQuack]

Cobalt/Molybdenum glass. They look the best out of all of them. And yes, I would like to see you showing us the IR emissions.

[chrysshart]

I am a borosilicate lampworker and the different properties of metals in our colored glass are probably the most important factor in working. Temperature level, flame chemistry (more or less oxididing/reducing), and the length of time the glass is exposed to specific temperatures all effect what color a glass will turn out (within the range of that mixture, of course) based on the metals within. We can also layer transparent colors over each other (as well as over opaque colors) to get dramatic effects as the light bounces around between the layers. Thank you for making this wonderfully in-depth video on how the metals in glass interplay with light to produce different colors!

[armadillobits]

This is awesome! I love the precise safety warnings before your videos. That’s something most science channels don’t do

[Zenodilodon]

I love the color change of the glass under different lights, I have to pick up some for myself because it's just so cool! I did not know neodymium doped glass changed.

[cybercapri]

Your videos are simply wonderful they're a joy to watch and I appreciate all the work you put into him

[GeekIWG]

Light and its interactions with objects like this are always fascinating and very cool

[itwuivw]

Wasn't able to watch this immediately due to a phone call, but wow! Light really is such a cool thing! Also, the silver bead is easily my favourite! I love both the colour and the science needed for it to work!

[GalleryOfChameleon]

I could really watch this 2 or 3 times and still not pick up on all the information contained... stunning production, beautiful stuff

[nnelg]

THANK YOU. Not (just) for the video, but because I've been trying to find the name of that song (Lightless Dawn) for AGES.

[escott]

This is my first time seeing a video on your channel. That was very interesting and very well done too! I liked how you lined up the splits of the two different spectrums so we can easily see the differences. Great work!!!

[ZanyGod]

In a way, it's like the light properties of a rare gemstone, the Alexandrite, which changes color when exposed to various forms of light. Thank you for your informative vlog.

5:17 I really like Erbium glass and Cobalt glass colors. Tungsten glass is also nice.
