August 18, 2018, Coloradoite, Mercury Teluride

August 18, 2018
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:

 

Greetings from the Bluff Park Back Porch on scenic Shades Mountain, 1,109 feet.
These minerals below can be found all around the world, most of which are used in a variety of different everyday products…. and oh yeah….
They’re also some of the most toxic materials known to science!

1. Coloradoite

1
Coloradoite, also known as mercury telluride, are recently discovered crystalline minerals formed when mercury fuses with tellurium. Since mercury and tellurium are both extremely toxic the combination of the two elements poses a serious risk of poisoning if carelessly handled.

Also, if coloradoite is heated or chemically altered, it can create a deadly vapor that you wouldn’t want to breath into your lungs

Coloradoite, Pyrite, Quartz-338840.jpg
Coloradoite, Pyrite, Quartz Locality: Bessie G Mine, La Plata District (California District), La Plata County, Colorado, USA (Locality at mindat.org) Size: 10.1 x 4.7 x 2.8 cm Coloradoite is a rare mercury telluride named for the type localities which are in Colorado. It is found in hydrothermal, tellurium bearing precious metal veins. Crystals and platelets of grayish-black coloradoite, accented with brassy, microcrystalline pyrite richly cover the sculptural vein matrix of quartz. Very seldom will you see a coloradoite specimen in cabinet size quality and richness.

It is used as a source of telluride metal.

What is the use of tellurium?

Uses. Tellurium improves the machinability of copper and stainless steel, and its addition to lead decreases the corrosive action of sulfuric acid on lead and improves its strength and hardness. Tellurium is used as a basic ingredient in blasting caps, and is added to cast iron for chill control.

Don’t smelt your gold ore on your stove while baking bread.
This one definitely is not very pretty to look at.
Thanks,

August 10, 2018, The Tragic Tale of the Radium Girls

Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
Radium is highly radioactive and its immediate daughter, radon gas, is also radioactive. Exposure to radium, internal or external, can cause cancer and other disorders.

Grace Fryer, One of the first Radium Girls.

The radium industry hadn’t reckoned with the courage and tenacity of the radium girls themselves

1921 magazine advertisement for Undark, a product of the Radium Luminous Material Corporation which was involved in the Radium Girls scandal. Retouched version

The Radium Girls were female factory workers who contracted radiation poisoning from painting watch dials with self-luminous paint.
The women in each facility had been told the paint was harmless, and subsequently ingested deadly amounts of radium after being instructed to “point” their brushes on their lips in order to give them a fine point; some also painted their fingernails, face and teeth with the glowing substance. The women were instructed to point their brushes because using rags, or a water rinse, caused them to waste too much time and waste too much of the material made from powdered radium, gum arabic and water.
From 1917 to 1926, U.S. Radium Corporation, originally called the Radium Luminous Material Corporation, was engaged in the extraction and purification of radium from carnotite ore to produce luminous paints, which were marketed under the brand name “Undark“. The ore was mined from the Paradox Valley in Colorado[2] and other “Undark mines” in Utah.[3] As a defense contractor, U.S. Radium was a major supplier of radioluminescent watches to the military. Their plant in Orange, New Jersey, employed more than a hundred workers, mainly women, to paint radium-lit watch faces and instruments, misleading them that it was safe.
An estimated 4,000 workers were hired by corporations in the U.S. and Canada to paint watch faces with radium.  Many of the workers became sick. It is unknown how many died from exposure to radiation.
The Radium Girls’ saga holds an important place in the history of both the field of health physics and the labor rights movement. Radium paint was still used in dials as late as the 1960s.[13]

The Radium Girls were so contaminated that if you stood over their graves today with a Geiger counter, the radiation levels would still cause the needles to jump more than 80 years later.
It is a sad tale that other women suffered from radium hair gel, toothpaste, powders, creams, lotions, lip stick and count less other products.

August 4, 2018, Calcium Carbonate

August 5, 2018
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock build mainly of calcite) and is the main component of pearls and the shells of marine organisms, snails, and eggs. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It is medicinally used as a calcium supplement or as an antacid, but excessive consumption can be hazardous.

 

Calcium carbonate is widely used medicinally as an inexpensive dietary calcium supplement for gastric antacid[26] (e.g., Tums). It may be used as a phosphate binder for the treatment of hyperphosphatemia (primarily in patients with chronic renal failure). It is also used in the pharmaceutical industry as an inert filler for tablets and other pharmaceuticals.[27]
Calcium carbonate is used in the production of calcium oxide as well as toothpaste and has seen a resurgence as a food preservative and color retainer, when used in or with products such as organic apples.[28]

 

Calcium carbonate is added to many foods such as ready-to-eat breakfast cereals and cereal bars, milk alternatives such as soy or almond milk, and some baked goods. The Daily Value — developed by the U.S. Food and Drug Administration for labeling purposes — provides a set value for nutrients. The established DV for calcium is 1,000 milligrams, so a food with 25 percent of the DV for calcium would provide 250 milligrams per serving. A serving of Total Whole Grain cereal — manufactured by General Mills — provides 1,000 milligrams of calcium per serving. Kellogg’s Nutri-Grain cereal bars meet 20 percent of the Daily Value for calcium. Two Kellogg’s Eggo waffles contain 25 percent of the Daily Value. Silk brand’s soy and almond milks each contain 45 percent of the Daily Value for calcium or 450 milligrams in a 1-cup serving. Not all cereals, waffles and non-dairy beverages contain added calcium. Compare the Nutrition Facts labels to determine which brands meet your needs.

Calcite
Sarbaiskoe Deposit, Kostanay Province, Kazakhstan
This specimen is considered to be one of the best calcites to have come out of Kazakhstan. Perched on a matrix of limestone is a large crystal of calcite in a beautiful golden-yellow color that is absolutely striking. The faces have a lightly frosted appearance giving the crystal a very soft and delicate translucency. Between the rich color and sculptural form, this specimen has great aesthetics and a lot of character.

July 28, 2018, Baking Soda

July 28, 2018
Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
A most useful compound in our daily lives.
Sodium bicarbonate (IUPAC name: sodium hydrogen carbonate), commonly known as baking soda, is a chemical compound with the formula NaHCO3. It is a salt composed of sodium ions and bicarbonate ions. Sodium bicarbonate is a white solid that is crystalline but often appears as a fine powder. It has a slightly salty, alkaline taste resembling that of washing soda (sodium carbonate).

Medical geology is an emerging interdisciplinary scientific field studying the relationship between natural geological factors and their effects on human and animal health.[1]
Not all elements and compounds are negative.   Some are essential for life, as in sodium chloride, halite or salt.
The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium.
______________________________________________________________________________________________________
Salt (halite), table salt or common salt is a mineral composed primarily of sodium chloride (NaCl).
Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation.
Some of the earliest evidence of salt processing dates to around 8,000 years ago.

 

Its major industrial products are caustic soda and chlorine; salt is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products.
Sodium is an essential nutrient for human health via its role as an electrolyte and osmotic solute.[1][2][3] Excessive salt consumption may increase the risk of cardiovascular diseases, such as hypertension, in children and adults. Such health effects of salt have long been studied.

Greetings from the Bluff Park Back Porch, way up yonder on Shades Mountain (1,109′) in Alabama:
A brand new topic for me to jump into.  Enjoy. comments appreciated.

The right dosage differentiates a poison and a remedy.”[2

Medical geology is an emerging interdisciplinary scientific field studying the relationship between natural geological factors and their effects on human and animal health.[1] The Commission on Geological Sciences for Environmental Planning defines medical geology as, “The science dealing with the influence of ordinary environmental factors on the geographical distribution of health problems in man and animals.”[2]
Back in 1966 at U of A I wrote a paper on Medical Geology, before internet and search engines, so had to go to library.
At the time it sounded terribly exciting even up to the point of a career choice.
In its broadest sense, medical geology studies exposure to or deficiency of trace elements and minerals; inhalation of ambient and anthropogenic mineral dusts and volcanic emissions; transportation, modification and concentration of organic compounds; and exposure to radionuclides, microbes and pathogens.[3]
Examples of research in medical geology include:
Diseases include iodine deficiency, cardiovascular disease pending amounts of magnesium and calcium, natural radiation, fluoride, selenium, potassium, calcium, and phosphorous.
Not all elements and compounds are negative.   Some are essential for life, as in sodium chloride, halite or salt.
The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium.

Recipe: Easy Homemade Southern Peach Ice Cream

©From the Kitchen of Deep South Dish

Inactive/Prep time: 2 hours 30 minutes | Yield: About 2 quarts


Ingredients

  • 4 cups of chopped, fresh peaches (about 8 large)
  • 1 cup of granulated sugar
  • 1 (12 ounce) can of evaporated milk
  • 1 (3.75 ounce) package of instant vanilla pudding
  • 1 (14 ounce) can of sweetened condensed milk
  • 4 cups of half and half
  • Electric ice cream freezer machine
  • 5 pound or larger bag of ice
  • Rock salt

Instructions

Peel, pit and cut the peaches into chunks. Place into a bowl, sprinkle with the sugar, stir; allow to rest for about 1 hour, stirring occasionally. Hand mash, or place peaches and juice into a food processor and pulse about 3 to 4 times, until mostly pureed. Set aside.

Whisk together the evaporated milk and pudding mix until well blended. Add the peaches, sweetened condensed milk and half and half and whisk well. Pour mixture into the container of an ice cream freezer and process according to the directions for your freezer. Once the process is complete, transfer to a container and place into the freezer until firm.

Note: To peel peaches, bring a small pot of water to a rolling boil and using a slotted spoon, drop 2 to 3 peaches in the boiling water at a time, return to a boil and allow peaches to sit in the boiling water for about 30 seconds. Remove and peel off skin. When fresh peaches are not in season, substitute canned, drained or thawed frozen peaches. One pound of frozen or canned peaches is equal to about three medium peaches.
