Apparently curiosities from Maximos Critelli's career are becoming something of a theme. The history around this product is quite interesting, as the original reagents are noted as "icelandic lava salt" and "face powder." While this is an excellent way of indicating how an alchemist may draw useful elements from anywhere, it's impractical and expensive to track them down. Their common names are Stabilized Fire and Stabilized Earth.

That aside, I'll spare you the history lessons. This reaction is quite tricky to compress, but the resulting hexagon is quite satisfying, with moving parts just squeaking past each other. There's some unfortunate cycles lost here, due to the squeeze, and I believe a redesign could likely do better than I have. Nevertheless, I'm proud of this solve.
