"Faraday Wax" - recreating old school high-vacuum epoxy!

Was hoping to see at least a glowing electrode at the end of the video, so frustrating! ;D
So far I could only find 3 years from the "Journal of Scientific Instruments" (on the Internet Archive: Vol. IV 1926-27 and Vol. V - 1928). I would like to browse more of those journals. Not looking for a particular number or a particular subject, just interested in vintage scientific instruments and history of science, in general.
- Is there any place where I can get more years from the collection of "Journal of Scientific Instruments"?
- ChristofferB, do you have any link for Vol. 13/1936 shown in the video (or can you PM a copy of it if the link is not public), please?

Thanks!
No glow discharge this time ;D the thought didn't hit me. It might be a good way of cleaning something like a Faraday cup, actually.
Journal of Scientific instruments is not as interesting as its spiritual successor "Review of scientific instruments - that's still running today"
I can't share the paper, unfortunately, as I only have access through my Uni, and I don't want to rock the boat that much - journal publishers are notoriously unfriendly towards sharing..
I can say, though, that aside from the faraday wax and the mention of Apiezon W, the rest was less interesting.
Here is the review that linked me to that article, though:

Very interesting thread and videos.
Thanks for sharing your vacuum knowledge

Great video and technique, i think I have all ingredients on hand, will give it a try -- thanks! For those interested, here is a link to Faradays Chemical Manipulation paper from 1827. So interesting reading these old publications!

I made two small test batches. One with red oxide, one with ultra-fine alumina powder. I'M very happy with the product.
Adding a tiny amount of Orange Oil to the melt made a flexible sealing material that while not useful for vacuum, is an otherwise interesting sticky compound. I'm waiting to see if the natural solvents diffuse out.

There's a little something called SciHub, courtesy of the friendly Russians... ;)
