Regarding "Avoid storing pieces in high humidity areas", it's not necessarily a high humidity that causes the most problems, it's fluctuations from high(er) to low(er) humidities. If pieces (implying even the original wood harvest itself) have been properly prepared, keeping them at consistently high(er) or low(er) humidities isn't normally a problem. The problem is changes (especially rapid ones) in humidity which cause the natural stress points in the wood to fail prematurely.
One additional note, coincident temperature fluctuations exacerbate the risk over time.
There has been some recent discussion regarding the proper care of wooden chess sets. I've created this thread for others to share their tips for cleaning and storing chess pieces, boards and other equipment.
I've reached out to a few manufacturers, resellers and restorers of chess pieces and will include some of their tips here. I'll update this first post as I get more advice from others.
