Preface    

     Welcome to Summer at DMS!  We’ll be taking a break from our regular series
until the Fall.  Please do join us for a Tellurium Picfest!

     So, get ready for a rare glimpse with this month's favorite: Tellurium!  Let's go!

 

Introduction

     Welcome to another annual Mineral Picfest summer article! 

     We’re going ‘native’ this Summer with our Mineral Pictfests! In June, we honored Gold. Now,
in July we are featuring Tellurium. August brings our short theme to a close with Copper. Enjoy!

 

A Brief History

     Discovered in 1782 by Muller von Reichenstein, this rare metal he named after the Latin tellus,
meaning 'earth'.  In its native form and in compounds, it can be attractive, yet toxic to humans, if
you choose to work with them.

     Tellurium is a metal that rarely occurs native, so various natural compounds have formed in
nature as minerals. Three major examples of telluride minerals are: Calaverite (a telluride of gold),
Sylvanite (a gold/silver telluride), and Tellurite (a tellurium dioxide).

     This element likes to be in the company of other metals; so, let's enjoy photos of our metallic
friend.

 

      Yes, it's our club's 50th or 'Golden' Anniversary! Though Gold is the traditional metal ascribed to such observances, we shall honor this tradition, as in last month's MOTM article: Gold. I wonder what year-level anniversary we could attribute to Tellurium? Why not e-mail us with your suggestions. Enjoy your summer. Oh, and for our visitors from the southern hemisphere, have a great winter!

Uses

     Tellurium has so many uses. From an additive to metal alloys, such as steel, aluminum, copper,
tin and lead. (Even the Tin Man in the 'Wizard of Oz' may have been part Tellurium.)

     Rubber's strength, quick curing, and longevity attributes these benefits from the addition of this
native metal. Scientific glasses and optics, ceramics, and high-tech devices (like solar panels) use
our favorite metal to improve their function, as well.

     There is even Tellurium in the soil, and plants uptake it in their lifecycles. Perhaps there is a
scientific 'Tellurium Cycle' to be discovered as part of nature. Will you be the one to research it?
If so, please do tell us at info@delminsociety.net.

    Tellurium metal and compounds are toxic, so I wouldn't suggest using it in jewelry or lapidary.
Though, some copper and steel products contain small amounts.

Invitation to Members

Members,

Want to see your name in print?  Want to co-author, contribute, or author a whole Mineral of the Month article?  Well, this the forum for you!

And Members, if you have pictures, or a story you would like to share, please feel free to offer.  We'd like to post them for our mutual enjoyment.   Of course, you get full photo and author credit, and a chance to reach other collectors, hobbyists, and scientists.  We only ask that you check your facts, give credit where it is due, keep it wholesome for our Junior Members watching, and keep on topic regarding rockhounding.

You don't even have to be experienced in making a webpage.  We can work together to publish your story.  A handwritten short story with a Polaroid will do.  If you do fancier, a text document with a digital photo will suit, as well.   Sharing is the groundwork from which we can get your story out there.

Our club's webpages can reach any person surfing the net in the world, and even on the International Space Station, if they have a mind to view our website!

We are hoping for a possible tie-in to other informative programs upon which our fellow members might want to collaborate.  Contact any officer or board member with your suggestions.

Our next MOTM will be a surprise.  For 2010 and beyond, we are waiting for your suggestions.  What mineral do you want to know more about?
