Monthly Mineral Chronicles Volume 3 Issue 4 is now available.

This month, in this 127 page full-colour issue, we have lots of  examples of things you can do while you are isolated. Also, articles on  darkfield illumination, the Defiance Mine, Gleeson, Cochise Co.,  Arizona, the minerals of the Don Hill Cutting, Devonport, Tasmania and  reports on the Hobart Mineral Show, Tasmania, the  International Mineral  Show, Rijswijk, Netherlands, and more on the Tucson Show with Paul  Stephen Cyr.

After I received Brian Beyer’s article on darkfield illumination, I  had a go at building something using black card. It works quite well.

Available here.
