Speaking of labels,
Do you have any old mineral specimens whose labels make no sense to you?
They might describe strange materials (Bergkrystal, Ghassoul);
They may come from bizarre places (Styria?);
They may be written in handwriting a doctor would envy;
Or they may be written in a foreign language.
Maybe I can help! I can read technical German, Spanish, French, and Portuguese, and work my way through some Russian, Ukrainian, Latin, and Greek. I am also familiar with old styles of cursive writing and with Fraktur.
Contact me at firstname.lastname@example.org if you could use these services. My rates are reasonable.
