MSA MEETING PROGRAM & PLACE

Online Event September 17th, 2020 @ 7.30 pm Arizona time

"Cleaning and Mineral Prep 101
- Why Do We Clean and Trim Specimens?”
Presented by Mr. Les Presmyk


SEPTEMBER meeting will be virtual via ZOOM.

The MSA September 17th program will be presented by our own Mr. Les Presmyk, "Cleaning and Mineral Prep 101 - Why Do We Clean and Trim Specimens?” His program will discuss how to further process rocks & minerals we collect. Once collected, most specimens only require a good washing and they are ready to be proudly displayed. However, what about those quartz crystals with all of that rusty stain or caliche stuck to them? Or the beautiful 3/4” wulfenite crystal perched on a 6” chunk of rock? Just like any profession, trimming and cleaning minerals require the right tools, significant knowledge and experience, and the willingness to risk the specimen.

Three things to remember before cleaning or trimming your specimens:

  • There is always a risk.
  • Try not to exceed your knowledge.
  • If you are too nervous to try, pay a professional.

Mark the date on your calendars as Mineralogical Society of Arizona is very lucky Les present this very educational program!
