[@sprichard304]

As I watched this last episode I realized I have something that would help you with the glass cooling. I bought a lot from a precision glass manufacturer auction a few weeks ago. It included what was labeled as a cooling table. It’s basically a heated table so you don’t get the quick thermal shock and you could slowly cool the glass. It’s yours if you want it.

[@kutz0420]

Hey man. You need to try using graphite for any glass molds. Molten glass will not stick to it. Most of your failures seemed to be from thermal shock but you cold get a much smoother starting point by using graphite on the pieces that did make it through.

And the cool thing about using graphite for this is that it's a directly mineable resource -- there are graphite mines in the united states.

If you want better cast glass, make the programmes on your kiln slower! The plaster will be more likely to crack from thermal shock if it heats too quickly. Also, unless you want really bubbly glass, try to keep your chunks as large as possible. The smaller pieces trap more air, so getting the glass free of bubbles will take much much longer at melting temperatures to allow the bubbles to rise out.

It simply cannot be done. However, on the educational side of the content, I think it's spot-on. The break-down of the processes is very detailed and we get a fair glimpse on how things have to be sourced from so many varied locations, with him actually going there, showing it to us, and doing as much of the sourcing as he can. And a good portion of the manual labor himself. When he gets to a point where he'd have to say "uhhh guys give me a couple of years to make this little part here that I'm gonna show you for 30 seconds in the video", heck, yeah, I think it's fair to take some calculated shortcuts.

I am unclear on the use of that glass panel you made at the end. You mention you project on it (and hemp), so am I right to assume the light captured by the lens is cast on it and then that surface is filmed to get the resulting image digitally (similarly to the film in a camera, or truck-wall in a camera obscura truck)? What are the reasons translucent (+ ground to become further less transparent) glass is better than hemp or film (or just a solid truck wall)? And which side is the camera (for digital video in youtube) or film (that end result) placed of this glass pane?

[@jameskaminski2813]

It's to act as a view port of sorts, so you can frame up shots before exposing them. the light hits the glass and you can view it from the outside of the camera (under a hood usually) then you can take the image by sliding exposure plates over-top.

You have successfully done the most comprehensive demonstration I have ever seen on why camera lenses are soo expensive!... AWESOME JOB!!!

[@wallabyparty5443]

Maybe you should heat the thing you pour your glass onto... it may help with the shattering.

[@TheAceofFate]

Been wanting to do something very similar for telescopes. Thank you for showing me every which way NOT to go about this.... My top contender so far is going to be, I think, spin casting to achieve the perfect concave I want for big reflector scope. Just gotta do the math and find out exact RPM to set spinning then dump in the resin mix, come back the next day and it should be ready to aluminize and get to work.

Your next big project should be a lathe.

Hey Andy! I'm a glass maker in Seattle , we use erbium in very small amounts as a decolorant.

I really Leica this video!

Awesome channel. A potentially easier way to measure index of refraction, that works with irregularly shaped shards, is to use a heater and something like cooking oil. The idea is that the index of refraction varies with temperature, so you just vary the temperature until the shard effectively disappears. Then you can look up the index vs temp on a table or do a simpler experiment on the oil directly (brewster's angle?). Supposedly this method was used in forensics to identify index of headlamp glass at accident scenes. the idea being that each manufacturer used different glass with a unique index. I don't know if this is true or not, but I remember hearing it from Prof. Manfred Fink at UT, so it's worth a shot.

You have got to be the clumsiest guy! I swear, I've lost track of how many times you've dropped something off camera and killed tons of your effort.

I am actually quite amazed you managed to get an image on a cyanotype from your camera (even if there isnt much contrast). The cyanotype reaction requires quite a lot of energy to happen, and is mostly sensitive to UV radiation rather than visible light. On top of that, glass blocks most UV rays, so it's quite incredible you could expose from only 7 hours of dim winter light !

[@Shrimp_Insurance]

There's actually a guy here on youtube who did some experimenting with cyanotype photography using his medium format camera, turned out pretty neat! He also talked about his inspiration for the project which was a guy who used a glass garden globe and a cardboard box as a camera to take cyanotype negatives

This cool and all, but you would think that Andy would have a better grasp of all of these skills by now. How many times have you worked at pouring metal? It seems to me that if you actually spent the time learning how to do things properly this show would be far more interestng. Cuz it so far it just is a show about you kinda making things, and not actually finishing anything

[@Darksagan]

Its so cool that the community has joined in to assist. Amazing channel and project.

Now I feel like I could make a crappy youtube video. I have a forge and some dirt.

[@ryanbrown172]

When you put the molten glass on the metal plates, the conduction of heat to the metal is so fast that it is not ideal for slowly cooling the glass down.

Getting the help of a highly specialized metal worker and his industrial tools isn't really the point of this show now is it? The final result isn't supposed to be perfect . I thought the whole idea was that you make everything yourself lol

I don't see how learning from an expert is contrary to doing things by oneself. Why not learn from others?
