6hlkmis ((MAN GROWN QUARTZ)) $10 MINIMUM BID, W W II vintage from Penna., 16 x 3.5 x 2 cm, Cabinet, | |
Here is are man grown Quartz from W W II era. I had a several hundred of these which sold very well a few years ago in Tucson. I just came across a box with 10 that did not go to Tucson. These are all undamaged ones that I set back. Quartz like glass chips rather easily and most had damage. This one does not except for a few micro chips. This is the smaller style. These were grown in Pennsylvania and the quartz, silicon used by the government. Now Quartz is still grown for computer chips. |
