Transparent glass Sodium downs cell tests (Patrons only) (Patreon)

Hello Everyone! I've been testing the feasibility of making a transparent glass sodium downs cell to hopefully see the inside of it working above 800 degrees Celsius. I've made a brief update video about the results. There's a few other video's I'm still working on with all sorts of tests (Especially for the resin telescope mirror) that might still take a while to complete, but I can soon post updates on how that's going before the final video is made.

I hope you all look forward to seeing these projects be completed and how they turn out

Thanks for all the support! :)
