TinDrum'Plutonium has been described as a physicist’s dream and an engineer’s nightmare because of its superb nuclear properties and confounding physical properties. Compared to uranium, plutonium is more efficient at fission...But it has six different phases, or crystalline forms, that vary in density by up to 25 percent, and modest changes in temperature or pressure can provoke it to go from being as malleable as aluminum to as brittle as glass'

Miro CollasPeebles Hoard features tin-enriched bronze – The History Blog

"This likely suggests that a rarely observed technique was used in the creation of the Peebles Hoard. Rather than tin plating or tin dipping, this probably represents a deliberate surface enrichment of the bronze where the tin was drawn to the surface. It is a remarkable and rarely observed process from Bronze Age Britain that requires more work to understand."
dB CooperThe mystery of the “Trewhiddle ingot”: evidence of the smelting of tungsten in Cornwall before tungsten was first isolated and characterized - in fact, before such smelting was thought to have been technically possible?
Or just weird slag?
And what does it all have to do with Baron Munchausen?

Hunter-Gatherer Metallurgy In The Early Iron Age Of Northern Fennoscandia Was Integrated And Advanced - Ancient Pages
Groundbreaking and extensive evidence shows that iron technology was integrated and advanced in hunter-gatherer societies in Northern Fennoscandia during the pre-Roman Iron Age (c. 200–50 BC). Smelting processes at high temperatures had been mastered, including using extreme temperatures in the furnaces.
AngryArtistHeating up a Damascus hunter for heat treat. During this process, the steel is brought up to critical temperature, then plunged into warmed oil. This rapidly cools the steel, locking the crystalline structure into place. This structure is very hard, but brittle, so it will then be heated just enough to allow that structure to relax and loosen slightly.
