Happy October!

October Greetings,

Mama's Readers!

Some facts: October is the tenth month of the year in both the Julian and Gregorian Calendars. It's name derives from the Latin "octo" meaning "eight," because it was the eighth month in the old Roman calendar (January and February were inserted later).

October plays host to numerous holidays, both lesser known (National Fire Prevention Week, Children's Book Week, World Animal Day) and popular, with the best-known being our beloved Halloween.

Mineral skulls, coyote and owl fetishes, and a large jade toad all
make additions to your Halloween decor or craft projects!

Halloween and its cousins Samhain and El Día de los Muertos (Day of the Dead) sit neatly at the end of the harvest season, reminding us of their agricultural roots. While Halloween in many places is now about dressing up and trick-or-treating, its derivations are far older: while some scholars debate its origins, it's pretty safe to say Halloween evolved out of European festivals that combined celebrating a bountiful year with honoring those that had died during the previous solar cycle. Samhain (pronounced SAH-win or SOW-in) was the "summer's end" celebration that did just that, and is still celebrated by NeoPagans today.

Skull beads at Mama's can make Halloween fun!

In the Southwest, we are lucky enough to be able to celebrate the Day of the Dead alongside Halloween, although they are not the same holiday. El Día is a Mexican holiday celebrated around the world, gathering family and friends to honor the dead in a festive, loving atmosphere. Fun and beautiful sugar skulls, calaveras (skeleton figures posed in every day activities), and personal altars (which often include marigolds, pictures of dead loved-ones and things they liked) all serve to remind celebrants of the joy, fragility, nobility, and preciousness of life.

At Mama's Minerals, we always have things to celebrate whatever version of these holidays you like: mineral skulls, skull beads galore, crystal balls, various Zuni fetishes (sometimes we have bats,cats, and wolves!), metaphysical supplies, and a host of other things to complete your holiday. Come see us, and . . .

Happy Halloween!

Blessed Samhain!

and a Día de los Muertos filled with fond memories of your loved ones!

Titanic: The Artifact Exhibition at New Mexico Museum of Natural History

On April 15, 1912, the world’s largest ship sank 963 miles northeast of New York City after colliding with an iceberg. Most people, young and old, know of this ship -– Titanic, the ship of dreams, the ship that regretfully came to a tragic end.

However, from this tragedy emerged heartfelt stories of the passengers that were on the ship that fateful morning when Titanic sank. Details of the ship’s demise became worldwide news and still, to this day, the history of Titanic lives on.

And now, visitors to the New Mexico Museum of Natural History and Science will have the opportunity to learn of the compelling human stories of those passengers on board through viewing Titanic: The Artifact Exhibition, featuring authentic artifacts recovered from the wreck site of the world’s most famous sunken ocean liner. Visitors can experience accurate recreations of the ship’s interior and can even experience the true nature of an iceberg.

Mama’s Weekly Rock Facts – Tiger Iron

Tiger Iron Skulls!

Tiger Iron is an altered mixture of layered red jasper, hematite, and tiger eye used mostly for jewelry making and ornamental stone carvings.  There’s not a clear consensus on whether tiger iron is a sedimentary rock, metamorphosed japilite, banded iron formation, or both.  If sedimentary, then stromatolite films may have facilitated the layering of sediments to form the banding.  If metamorphic, tiger iron would form at plate subduction zones where a tectonic plates moves under another and sinks into the mantle.

Mama’s Weekly Rock Facts - Soapstone

Soapstone which is also known as steatite or soaprock is a type of metamorphic rock called talc schist.  It is largely composed of talc which is the softest mineral on the Moh’s Hardness Scale with a 1.  Soapstone is relatively soft and may feel soapy, waxy, and or greasy when touched, hence the name soapstone.  

Soapstone Rough Rock

Soapstone has been used for centuries as a medium for carving and even as a building material.  In locations where it is prevalent such as India and Brazil, soapstone was used to build temples and pave roads.  With its variety of colors in greens, browns, grays, and whites soapstone continues to be one of the most common carving materials.

Lapidary Tips – Cabochon Polishing Tip

Lapidary Tips – Cabochon Polishing Tip by Dick Peterson, TG&MS  

About 15 or 20 years ago, when I was cutting a lot of Bertrandite, I ran into a problem I hadn’t seen before. I had been shaping and sanding and polishing a lot of cabs when I had one that wouldn’t polish. The stone was a deep dark purple, one that I though would be outstanding. I went back to my Genie and re-sanded it and tried polishing it again. No luck. I set the cab aside and forgot about it.

Snowflake Obsidian 25mm Cabochon

            One day I was using some acetone and I spotted the cab so I cleaned it in the acetone. I then washed it in Dawn® Soap and warm water. Then I tried it again on the polishing wheel…it took a beautiful polish! What had happened during the cutting stage? It had been cut with oil and it had absorbed some oil. Oil is not a friend in cutting and polishing cabochons.

            If you suspect that the rock you are about to cut will absorb oil (some softer rocks do this) try the following before you cut it. Soak the rock in water for 24 hours or longer (longer is better). In the summertime put the container of the soft rock in the sun where it can warm up (the warmer the better). Keeping it warm helps the rock absorb more water. Next put the rock in the slab saw and cut it as soon as possible. The oil will slowly replace the water in the rock. Now is a good time to wash the slab with acetone. Anytime you cut slabs in your slab saw you should always place your slab in kitty litter (which is a great way to suck out the unwanted oil), wash your slab in warm soapy water. Dawn dish soap is one of the best to use.
