This isn't quite a live report as I'm now in Poland, internet in the Czech Republic was too poor to be able to do the live report 'live'. But the visit was too important not to document, so here's our flying visit to Jáchymov in the Czech Republic documented. Arriving late yesterday evening, we passed the impressive 'Hotel Radium'. Of course this town is famous for Uranium mining and the Uranium ore from the mines in this area was used by Madam Curie to first identify the new element Radium.
Our main reason to visit was the museum, the Muzeum Kralovska mincovna Jachymov. We didn't really know much about it in advance other than it was originally the Royal Mint and holds a small mineral collection. So we decided to go in.
The first thing I was drawn to was this old Soviet XRD system. D`ials and switches are labelled in Russian, with stickers written in Czech on certain parts.
A notebook left by the machine (which curiously has a western style keyboard rather than cyrillic) shows the handwritten d spacings for Tilasite and Brandite noted down.
The first case of specimens shows slices of ore veins with minerals such as nickel arsenides, arsenic and silver highlighted.
Another cabinet of radioactive secondaries and post-mining minerals stored in plastic bags to stop them dehydrating.
Moving on through the museum to see exhibits on early mining and smelting, such as this early device for smelting ore.
My Czech and German are a bit rusty, but I believe this is Geogius Agricola, who in 1556 became the first lead singer of Metallica. He may also have written a book.
Upstairs, a more sobering display highlights the use of forced labour from around 1949 onwards to mine Uranium. Political prisoners were often condemned to an early death in the hazardous mining operations driven by the demand for nuclear materials by the Soviets.
Further on, we found the library. But wait, this is no ordinary library. This houses an incredible collection of very old and very rare books!
When he wasn't performing Heavy Metal, Agricola was busy writing the first real book on mining techniques.
Moving on, we find some charming old mining models. These were made in almost every mining district worldwide at around this time.
Katya is taking a photo of some vials that are labelled as being various uranium salts. I do hope they are fake!
Of course, once the radioactive properties of uranium and radium were discovered what did people do with them? They thought they had great medicinal use!
A selection of containers and other items relating to the radioactive spar treatments. Naturally radioactive water spa treatments are still offered to this day in the town, and are a big draw for many tourists.
Down in the cellar they have a reconstruction showing how some of the smelting of silver ore would have been done in this very building.
And of course, being the old Royal Mint, they have a fabulous collection of historical coins, with this pair dating back to Boleslav 1 (935-972AD)
Znucalite - one of those boring mineral names that is simply the major elements strung together. Unless you like that sort of thing in which case pyrite should be fesite, calcite should be cacoite, and eudialyte should be nacafemnsrsiooohhoohclite.
A little text, in two languages I can't read, talking about the UNESCO status of the area. This brings this not-quite-live report to a close, thank you for watching, tomorrow I start the reporting at the Luban mineral show (Crystaldays) here in Poland! Stay tuned!
