Everyday Uses of Thallium You Didn’t Know About

Posted by Diane Milner on Sep 17, 2018 9:03:00 AM

What Is Thallium Metal?

Thallium is a bluish-white hued metal found in trace amounts throughout the Earth’s crust. In its purest state thallium is both tasteless and odorless, and was once sourced from smelting other metals. Presently our sources of thallium rely on naturally occurring deposits. Thallium uses today commonly include the production of electronic devices, fiber optics, camera lenses, switches, and closures. Thallium metal is used most notably by the semiconductor, fiber optic, and the glass lens industries. Unfortunately, exposure to thallium metal is harmful to those working closely with the metal. When thallium enters the atmosphere, traces of the substance remain after its use in coal-burning and smelting. Thallium metals are detected in the air, water, and soil long after exposure.

Surprising Modern Uses of Sublimed Sulfur

Posted by Diane Milner on Sep 10, 2018 9:09:00 AM

What Is Sublimed Sulfur?

Sulfur is a naturally occurring mineral produced by volcanoes; its presence attributed to rife deposits of sulfur throughout the Earth’s crust and upper mantle. Commonly referred to as brimstone, sulfur is found in its raw state surrounding volcanic vents. The mineral is relatively light and reacts with all elements save for gold, platinum, iridium, tellurium, and the noble gases. Interestingly, sulfur produces the following compound sulfide minerals: pyrite, cinnabar, galena, sphalerite, and stibnite. Sulfates produced include gypsum, alunite, and barite.

4 Helpful Calcium Carbonate Uses You Forgot About

Posted by Diane Milner on Aug 27, 2018 8:26:51 AM
What Is Calcium Carbonate (CaCO3)?

Calcium carbonate is naturally found in rock and mineral formations. (Four percent of the Earth’s crust is comprised of the substance.) Calcium carbonate is slightly water soluble, and is thereby leached into natural water systems, resulting in “hard” water. Limestone and chalk are comprised of calcium carbonate– as are coral reefs. The mineral is typically procured via mining and quarrying. Calcium carbonate exists as limestone, chalk, and dolomite, and typically includes impurities like clay.

4 Smart Skincare Uses of Zinc Oxide

Posted by Diane Milner on Aug 20, 2018 9:02:00 AM

What is Zinc Oxide (ZnO)?


Zinc oxide is widely used throughout the skincare industry. In fact, recent developments within sunscreen production have found a new way to incorporate zinc oxide to eliminate the white residue left behind after application. Zinc oxide is derived from zinc, which is an elemental metal. Zinc is unique, as it can carry an electrical charge which communicates differently within the body’s internal organs. Most notably, the immune system, digestive tract, brain, and skin.


Zinc oxide is manmade and is produced by chemically heating zinc alongside oxygen molecules. Both elements are vaporized, condensed, and transformed into a fine white powder.

Top 3 Surprisingly Versatile Uses of Sodium Hydroxide

Posted by Diane Milner on Aug 13, 2018 9:03:00 AM


What Is Sodium Hydroxide?


Sodium Hydroxide (NaOH) is white and odorless solid. It is a common ingredient in cleaning supplies, and perhaps most notably appears in drain and oven cleaning chemicals. Sodium hydroxide causes skin to burn upon contact and will cause irrevocable damage if ingested. (See our safety sheet on Sodium Hydroxide.) However, sodium hydroxide is FDA approved and is “generally recognized as safe” (GRAS). Used across a multitude of industries, some applications of sodium hydroxide include textiles, soap and cleaning products, paper, aluminum processing, petroleum, and bleach production.

Surprising Antifungal Uses of Selenium IV Sulfide

Posted by Diane Milner on Aug 6, 2018 9:02:00 AM


What Is Selenium IV Sulfide?

Selenium IV Sulfide is principally leveraged as an antifungal agent. What you probably didn’t know is that selenium sulfide is commonly used in your favorite dandruff shampoo– so you can thank selenium sulfide for kissing your flakes goodbye! But that’s not where the magic ends. Selenium sulfide (SeS2) is derived from the naturally occurring mineral, selenium. You may be familiar with the widely popular crystal selenite, which is comprised of selenium. The crystal heralds striking, white striations and has received a resurgence in the new age market as a spiritual tool to achieve calm.

Potassium Iodide: The Thyroid Rescue Pill

Posted by Diane Milner on Jul 24, 2018 9:16:00 AM


What Is Potassium Iodide (KI)?

Potassium Iodide is a stable form of iodine. The substance typically appears as white crystals, granules, or in powdered form. The chemical is soluble in water, alcohol, acetone, and glycerol. On a consumer level, potassium iodide is commonly used to combat radioactive iodine as a means to protect the integrity of the thyroid. In fact, as of this month, Chester County in Phoenixville, Philadelphia began issuing emergency potassium iodide pills to mount a potential emergency response to radiation leakage from the Limerick nuclear power plant. Potassium iodide (along with potassium iodate) was commonly used to prevent goiter– an enlargement of the thyroid gland. It is still used today for such purposes, but other options are also available.

Did You Know Potassium Iodate Is Iodating Your Table Salt?

The Iodated Table Salt in Your Kitchen

Did you know your table salt most likely contains iodine? You have potassium iodate to thank for that. In an effort to revitalize iodine in the American’s everyday diet during the 1920s, the government sanctioned the inclusion of potassium iodate to combat a growing goiter epidemic– as we were dubbed “the goiter belt.” (We’re not the only ones who imbue our salt with iodine, 120 countries iozide their salt, including Brazil, Canada, Mexico, and Switzerland.)

An Industrial & Informational Overview of Sodium Cyanide

Posted by Diane Milner on Jul 9, 2018 9:15:00 AM


A Brief Introduction to Sodium Cyanide


Sodium Cyanide formula: NaCN


Sodium Cyanide (NaCN) heralds a molecular weight of 49.008 g/mol with a melting point of 563.888° F. The highly toxic salt commonly appears as a white solid and is redolent of almonds. NaCN is water, ammonia, methanol, and ethanol soluble. Sodium Cyanide is toxic to humans and must be handled with extreme care. A non-lethal dose of the substance has a half-life of 20-60 minutes. Sodium cyanide uses in industrial spheres provide a multitude of practical applications, with limited consumer use.
