90% platinum and 10% iridium for its virtual immunity to oxidization, and because it’s extremely hard-wearing
well thats bollocks. Platinum is hilariously soft.
There are a few issues, one is radioactivity. There are radioactive impurities that as they decay loose weight. Second, its postulated that there is a build up of trace amounts of mercury on the IPK due to environmental factors.
thirdly, they are not cleaned anymore. they used to be cleaned with shammy leather.
