Date(s): Dec 9; 4-7pm
Where: Mercer County District Library, 303 N. Main St.; Celina, OH 45822
Why: The chance to view over 900 mineral specimens in 27 cases with many more in storage. We will use incandescent light as well as long wave, short wave and mid wave UV to find fluorescent minerals.
The Langsdon Mineral Collection has arranged a special "Night in the Museum" event for members of the Richmond, Troy, Fort Wayne and State Line gem and mineral clubs. During this event, we will be able to visit the collection after hours, meaning we will be able to explore the collection using not only incandescent lighting, but also both long and short wave UV. While they have one case of fluorescent minerals, club members may be able to help identify many more. Additionally, only part of the extensive Langsdon collection is on display at any given time. This after-hours event will allow club members to view some of the other parts of the collection, as well. If you are interested in this unique chance to explore a great collection, please fill out the RSVP form to the left. You are not committed to going, and your information will only be used to contact you about this trip. Many of the specimens are newly discovered minerals from recently-opened mines in India, China and Pakistan. Other specimens are from historic mining areas, which are now closed to collectors. The collection contains pyrite, galena, quartz, tourmaline, apophyllite, stibnite and rhodochrosite, among many others. Each sample is labeled with the mineral type and place of origin.
