'Exporting' a few chips of rock internationally enforces capitalist values on matter that couldn't care less in awkward ways.
DE customs want invoices to prove what I've picked up from #MineWaste is worth (for a gift) so they can tax it.
The fact it's arsenopyrite is probably not an issue but - "Arsenic is a critical mineral and used in numerous industrial products including gallium-arsenic semiconductors for use in cell phones, solar panels, telecommunications, aerospace research and light emitting diodes (LEDs)"

Not one of mine, but a photo I made of a friend's specimen - amazing spherical #Hematite ("kidney ore") inclusions in water clear quartz. Some of the metallic spheres are split, so you can see how they grew from a tiny dark red core. Found in #MineWaste at Botallack mine, #Cornwall.

Much shinier (aka 'gemmy') than the last one - this 4mm cubic #Cuprite is from #MineWaste at Wheal Unity Wood - a mile or two away from Wheal Unity. A lot of these #Cornish mine names and distinctions are famously confusing!

Recently I've been making better images of specimens I found previously - this is a pair of complex #Cuprite crystals from #MineWaste at Wheal Unity, Gwennap I found in a 20 minute visit in 2023 checking sites for #OrganisedAtoms workshops (I should check it out again, found some amazing things here and somehow never returned). They have a thin coating of #Chrysocolla which gives them a hint of blue.
I'm still using the same cheap USB microscope, but I learned how to use Hugin (https://hugin.sourceforge.io/) better to make large resolution images. This is a composite image of 9 focus stacked images - each comprised of 10 to 20 images at different focal depths.

Squarish, tabular #Cerussite scattered across an orange matrix, surrounded by exposed #Galena with typical right angled breakage planes.
#Fossicked from #MineWaste at Wheal Clinton, Flushing, #Cornwall. Found below the high tide level, beneath the main shaft of an old lead/silver mine (now in a rich person's enormous garden overlooking the sea).
Some of the galena is tarnished blue indicating it has a high silver content (~3% according to historical records).

New research for Royal Society of Chemistry funded Organised Atoms workshops, using mine waste crystals in electronics.
This is a new design we've made for a synthesiser, it's a light controlled oscillator that uses a natural pyrite crystal (from Wheal Unity Wood mine, in Cornwall) to output sounds that change as you move tiny 'cats whisker' wires to different places on the crystal surface.

Daphnite, a type of Chamosite - #Fossicked from #MineWaste at Carharrack Mine, #Cornwall
First thing I've found that seems to be quite rare... Hexagonal stacks of deep green crystals, protected by a thick layer of fine clay, ultrasonically scrubbed clean.

I like noticing how as people get experience in any scientific field unintuitively they become more uncertain. Confusion on mindat.org as to whether this is arsenopyrite or pyrite. I was ~confident it was tetrahedrite, I'm pretty terrible at this still. I can't stop photographing these crazy shapes though.
As yet unidentified crystals #Fossicked from #MineWaste at Carharrack Mine, Gwennap #Cornwall. The gold is a coating of chalcopyrite that easily flakes off if you prod at it with a pin.

One of my fave recent finds: goethite which has grown to replace pyrite, so has inherited the cubic form and surface striations of a different mineral (this is called pseudomorphism). You can also see smaller acicular (thin & stick-like) goethite growing out from the surface, which is it's more normal form.
#Fossicked from #MineWaste at Wheal Unity, St Day, #Cornwall This was in a really heavy rock, mostly goethite, copper secondary minerals and possibly some native copper, from the tailings surrounding the remaining capped shaft on the site.

Listening to electrons spilling through semiconducting junctions in this galena #Fossicked from #MineWaste at Wheal Lovelace, #Cornwall.
The crystal is being used by one oscillator to modulate the frequency of another. With this simple setup you can experience the highly complex interactions between electrons and crystals grown hundreds of millions of years ago.
