[Rockhounds] mineral exhibit

[Alan Goldstein]

I am developing an exhibit on the use of rocks and minerals in our daily life. I have found plenty of information at www.mii.org and at the USGS. My plan is to set up an office with a computer, clock radio, desk lamp, metal desk and chair, etc. and display minerals used to make those products. (Also the floor, walls & paint, ceiling and room lights...)

I welcome exhibit suggestions. 

Question -- I'm going to display some dental picks. Does anyone know what materials were added to the steel for strength. I know that titanium, antimony, etc. are added to strengthen steel.
