Kyle Explains #8: Alcohol


Kyle Explains #8: Alcohol

I attempt to explain complicated things

Alcohol is defined by its chemical structure but not all alcohols are the same. Alcohol is used for a variety of purposes from cleaning to food flavoring to drinking. Drinking age restrictions vary by country, some have no restrictions on alcohol at all, while others prohibit alcohol completely. 

Alcoholic drinks are a tradition in some areas of the world and recipes can date back thousands of years, while bottles of drinks like wine, rum, and whiskey are known to be aged before selling. 

Alcohol is made by distillation or fermentation.  Distillation is a process of heating a mixture of water and vegetables, grains, or fruits to collect the evaporated steam. The steam is then cooled and processed and becomes the alcohol. Each alcohol is made with a recipe, for instance, vodka from potatoes and whiskey from grains. Vodka, gin, tequila, rum, whiskey, and brandy are some common alcohols that are distilled. Fermentation is the process of adding a chemical reactant, usually a type of yeast, to the fruit, vegetable, or grain mixture to chemically break down the mixture into alcohol. For wine, this is done with grapes. Beer, wine, cider and sake are common alcohols that are fermented. 

There are thousands of drinks that come from mixing alcohols and various juices, flavorings, plants, and food. Wine, bourbon, or other drinks are sometimes used for cooking or baking. Some alcoholic drinks are traditional to certain regions, such as beer to Germany, vodka to Russia, wine to Greece, France, and Spain, sake to Japan, or bourbon and whiskey to the United States. 

Alcohol is not only used for consumption. Methanol, ethanol, isopropyl, ethylene glycol, propylene glycol, glycerol, and menthol are all types of chemical alcohols. Chemical alcohols are used for various purposes. Methanol is added to gasoline in some countries. Ethanol was used for rocket fuel in WWII. Isopropyl alcohol is used for cleaning and hand sanitizer. Glycerol is used in E-cigarette liquid or vape juice and antifreeze. Propylene glycol is the other ingredient in vape juice as well as antifreeze. Ethylene glycol is another alcohol used in antifreeze. 

Alcohols come in different concentrations called proofs. Proof is measured on a scale of 1 to 200 and is twice the alcohol’s percentage by volume. For instance, 80 proof vodka is 40  percent alcohol by volume. Alcohol that is 200 proof is 100 percent alcohol by volume or simply a container of alcohol. Regulations differ by country what proofs can be sold and served. 

Note that I am not a medical professional or chemical professional and am not qualified to give medical advice. Beware that alcohol used for chemicals is not always safe for human consumption and to only consume things labelled for human consumption. While chemicals like glycerol and propylene glycol are commonly used in foods, this does not mean they are safe to eat in large quantities or in other forms found outside of foods. 

Alcohol has a complex and interesting history and a wide range of uses. It has been around for nearly 10,000 years and is an important chemical used for many purposes.

Kyle Explains #7: Precious Metals


Kyle Explains #7: Precious Metals

I attempt to explain complicated things

Precious metals are rare elements found on the planet. Their value is high because of their rarity and lack of abundance. Precious metals are often used in finance for trading or for their chemical abilities in things like microchips or mufflers. Precious metals and rare metals, or rare earth metals,  are both valuable but rare earth metals are something different completely. 

Gold is probably the most well known precious metal. Although not the most expensive or rare, it is the most widely used. From computer chips to jewelry, gold can be found in many things. Gold is used in coinage, bullion (bricks or coins held as value), art (gold plating), dental fillings, jewelry, watches, electronics, and for computer chips. Gold can be found in different concentrations or ‘carats’ marked by a K. 24K is pure gold, 22K is 91.7% gold, 18K is 75% gold, 14K is 58.3% gold, 12K is 50% gold, 10K is 41.7% gold, 9K is 37.5% gold. The most common are 24K, 18K and 14K. When gold is not 24K it is usually mixed with silver, copper, and other metals to keep its color or create other colors like rose gold or white gold. 

Silver is also used for a lot of common things. Silver used for bullion, mirrors, dental work, electrical components, in paints used on electronics, solder wire, batteries, jewelry, and for decoration and tableware. For instance the term silverware comes from silver and means any tools, usually cooking utensils, made from silver. Silver also comes in a variety of concentrations, 999 and 925 are the most common, while 900 is usually the grade required for bullion. The grade is simply 999 is 99.9% silver commonly referred to as fine silver, 925 is 92.5% silver commonly referred to as sterling silver, and 900 is 90% silver commonly referred to as coin silver. The other part is usually copper or nickel to keep its shiny property. Other types of silver fall between 92.5% and 99.9% silver, and are usually used for jewelry. 

Platinum is less known but has a wide variety of uses. It is used for catalytic converters in cars, magnets, electrical components, medical or lab instruments, sometimes in jewelry, for decorations, or dental work. Platinum is known for its ability to conduct electricity and for its lower price than gold. Silver and copper tarnish, or rust, while gold and platinum are strong conductors that don’t rust as easily. 

The other precious metals are known as the ‘platinum group metals’. Six metals that have similar physical and chemical properties. In periodic order they are: ruthenium, rhodium, palladium, osmium, iridium, and platinum. They are all used for similar things, mostly for causing chemical reactions in catalytic converters, except palladium is also used for dentistry and jewelry. 

Precious metals have been sought after since the beginning of time for their shine, rarity, and chemical or physical abilities. Their prices are very expensive, and still today they are not easy to come by. They are used in small amounts in many places, and large amounts of any of these metals is of great value. The Earth has limited resources and these surely have earned their title of precious.

Kyle Explains #6: Currency Collecting


Kyle Explains: Currency Collecting

I attempt to explain complicated things

Currency collecting is the hobby of collecting rare coins and paper money that are worth more than their face value for a multitude of reasons. Currency collecting is referred to as numismatics, stemmed from Old French and English words roughly meaning ‘coins’. Collectors often seek rare paper money or coins based on a low amount made, the age of the item, manufacturing defects, forgeries, or collectability reasons such as arcade tokens which hold no face value but are still sought by collectors. 

Currency collecting has been around as long as currency has been. One of the first coin collectors is widely accepted to be Agustus, the first Roman Emperor who gave old coins as gifts. While it’s subject to say he was a collector, the fact is true that he held value in old currency. This is what the basis of collecting currency is. Some collectors focus on one specific currency or category, while others have a wide collection of varying rare items with many types of historical importance. 

Some collectors focus only on paper money. The U.S. dollar bill is very collectible for many reasons, many are based on the serial number. U.S. dollars print a star note when they have to reprint a bill, these notes have an asterisk or star instead of a letter in the serial number. These bills are often rare due to the fact that there are fewer of them printed, some years less than 50,000 of these bills are printed. U.S. dollar bills also have a ‘twin bill’ where the serial numbers match. This is because they come from different printing facilities, and it is a rare occurrence. Serial numbers that are called ‘super repeaters’ are also very rare. When the serial number is 12345678 or 55555555, there’s a low chance that one bill came out with one of those numbers and they are highly collectible. 

U.S. coins are also very collectible. Old paper money is not found in circulation since it looks so different, some bills were red and you won’t see those in your change. Old U.S. coins on the other hand look very similar to new ones and can sometimes be found in your change jar. Wheat pennies are a collector item that are simply pennies made before 1958. They feature wheat grains on the back of them and look very similar to today's pennies. Another rare penny is the steel penny from 1943 and 1944. These pennies are silver in color and were made out of steel since brass and copper was used for the war efforts during those years. A 1944 wheat penny can go for more than $50,000 due to its limited production of only 50. Mercury dimes were produced until 1945 and feature the head of Lady Liberty, but were confused with the Roman goddess Mercury and given the name Mercury Dime. These too are still circulated on rare occasions.  

Other important collection items are forgeries. A good forgery can be worth more than an original item. This being said, I’m not telling you to start forging money. An expensive or rare forgery gets its value from the person who made it, not particularly the item in question. A fake dollar bill is worth nothing, a fake dollar bill made by Banksy is worth a lot - regardless of quality. Another Item that people collect in the currency realm is tokens. It’s not a perfect answer to what these fall under. A vintage arcade token may be worth more to someone who collects arcade equipment, while a vintage poker chip might be more valuable to a gambler, while a Big Mac token may be valuable to a Mcdonald's collector! Regardless, all three are types of currency that have historical value.   

Collecting currency is a pastime for many people, and the hardcore collectors can spend hundreds of thousands of dollars for one item. Old items are historically important and currency will continue to be produced every year making old items continually more valuable. The more you know about it, the more you’ll be checking your change at the grocery store!
