President’s Message

Hi, I hope all is well. Mike and I went to Albuquerque between 20-27 April. I had an opportunity to go to

The Museum of Science and Natural History. There were a lot of fine rocks and fossils there. If you make it

out that way, it is a great way to kill an afternoon and it won’t empty your pocket book. They have a huge

chunk of smithsonite there, but I couldn't figure a way to get it in my pocket. Oh lust, lust. We should have

a great meeting in May. We will have a guest speaker on paleo that day, so make it a point to make it; you

won't be sorry. See you then and God Bless. Harold

Mineral Wells Fossil Park, Mineral Wells, TX

A former ‘borrow pit’ for the city of Mineral Wells now gives visitors a chance

to collect fossils from the 300-million-year-old (Pennsylvanian) shale. Open all

day Friday through Monday at no charge, the site yields crinoids, bivalves,

brachiopods, corals, trilobites and much more. The Dallas Paleontological

Society has a volunteer program for this unusual public resource.

Ladonia Fossil Park, Ladonia, TX

Sediments in the bluffs of the North Sulphur River near Dallas yield all kinds of Cretaceous

fossils from mosasaur bones to ammonites, bivalves and shark teeth. The Pleistocene

sediments above have mammoth bones and teeth. This is a rugged, at-your-own-risk kind of

place where you need to watch for snakes, slides, feral pigs and sudden floods from controlled

water releases

May Birthstone

Source: http://www.americangemsociety.org/may-birthstone

Emerald

As the birthstone for May, the emerald, a symbol of rebirth, is believed to grant the owner foresight, good fortune,

and youth. Emerald, derived from the word smaragdus, meaning green in Greek, was mined in Egypt as early as

330 B.C. Today, most of the world’s emeralds are mined in Colombia, Brazil, Afghanistan, and Zambia. The

availability of high-quality emerald is limited; consequently, treatments to improve clarity are performed

regularly.

April 28, 2014 TXI Field Trip Report

A great adventure. The day started out warm and windy. After a short 47-mile drive from Plano to Midlothian TXI

cement plant, we met up with our group; TXI furnished ‘hard hat and safety glasses’ for those who needed them,

and off we went!

The hunting took place in large cleared areas, large mounds of dirt, rocks and boulders. We had a choice of

looking for sharks teeth, septerian nodules, marine fossils or pyrite. Having done this trip once before looking for

shark teeth, we chose to look for pyrite.

During the two-hour time, we found a bucket-full of marble and pencil size pyrite, and some larger pieces (2” x

2”), really nice to look at.

We enjoyed ourselves and are looking forward to going again. Thanks to David Dobson and the people of TXI

Cement Plant who made these trips possible.

Classes at the Shop

Qualifying Class. The shop only has 5 Genie's so we can only teach 5 students at a

time in the Qualifying Class. There is a waiting list of people who want this

class. So please register with Monika and she will notify you when she has a class

opening.

Other classes: Wire-wrapping, Metal Clay, Chainmail, Metal Smithing, etc. are

taught in the shop classroom. Due to space limitations we also limit the size of these

classes to 5 or less.

How to Register. If you are interested in taking a class, contact Monika Brown at

[email protected] . Ask to be placed on the Waiting List for the class you are

interested in. When Monika has an opening in a class she will contact you to ask if

you can attend on the date of the class. If you cannot she will keep you on the

waiting list. Once she has registered you she sends out a confirmation email

confirming your attendance in class. While you may be on the waiting list that does

not mean that you will be in the next class if we have a long waiting list.

Thanks for your understanding in this matter! We have a great group of volunteer

teachers so please tell them how much you appreciate their willingness to teach! If

you are interesting in teaching a class, bring some samples to the next meeting and

talk to Monika about your ideas.

“WHAT IS THE MOHS HARDNESS SCALE FOR MINERALS?”

Mineral Hardness is measured on a Scale: In 1812, German mineralogist Frederic Mohs penned what

would become what is referred to as Mohs’ Scale of Mineral Hardness. For his scale, he selected 10 minerals

based upon their being common and readily available. It should be noted that the scale is not actually linear but

rather arbitrary. Here is the Mohs Scale of hardness including the hardness number, the mineral associated and its

common uses.

Mineral Hardness 1 – Talc: Associations and uses: talcum powder

Mineral Hardness 2 – Gypsum: Associations and uses: Plaster of Paris. Gypsum is formed when

seawater evaporates from the Earth’s surface.

Mineral Hardness 3 – Calcite: Associations and uses: Limestone and most shells contain calcite.

Mineral Hardness 4 – Fluorite: Associations and uses: Fluorine in fluorite prevents tooth decay.

Mineral Hardness 5 – Apatite: Associations and uses: used to manufacture fertilizer

Mineral Hardness 6 – Orthoclase: Associations and uses: Orthoclase is a feldspar

Mineral Hardness 7 – Quartz: Associations and uses: is a lovely crystal and is often used in jewelry

Mineral Hardness 8 – Topaz: Associations and uses: The November birthstone.

Mineral Hardness 9 – Corundum: Associations and uses: Sapphire and ruby are varieties of

corundum.

Mineral Hardness 10 – Diamond: Associations and uses: Used in jewelry and cutting tools.

Hopefully now you understand the Mohs Scale of Hardness. Thanks for watching. If you’d like to

learn more, please find us on the web at About.com.
