I learned something new from the auctioneer. Do you know where the phrase "mad hatter" came from?
In the 18th century furriers used mercury nitrate to tan the furs of rabbits and similar small game and turn them into hat felt.
Mercury nitrate exposure caused tremors, emotional and mental instability and hallucinations and basically whacked out the hat makers, hence the phrase.
My mom's dad was a furrier that worked from home. My mom hated the chemical smell, was embarrassed to bring friends over. Wonder if it added to the cumulative family crazy?
