How does a "first surface" mirror work? (2^15 sub special!)

After a bit of a hiatus, AlphaPhoenix is live again! In this video I print some parts, coat them in resin, and chemically silver that resin surface, making a first-surface mirror akin to telescope optics but MUCH less precise. (also I use said silvering process to make a play button with actual silver!) Hope you enjoy the classic story of scientific failure and iteration, and maybe learn something about mirrors while you're here! If anybody is curious to try this themselves, this is very much not a sponsored video, but I was using Smooth-On's XTC-3D as my smoothing agent and Angel Guilding's Spray-Silvering chemicals to deposit the silver. if anybody knows more about these products that might explain some of the difficulties I've had, I'd be all ears!
