We are developing a small permanent exhibit on fluorescent minerals as part of a larger mineralogy museum and wondered if anyone has had experience developing this kind of exhibit (use of long and short wave uv tubes, darkened exhibit space, materials for labels, etc.) and might have any advice or suggestions - what worked, what didn't. Feel free to reply off the list. Thanks in advance.
