Chinese New Year Traditional Fireworks Display

Chinese-New-Year-dashuhua

500 years ago during the Ming dynasty, a blacksmith came up with a cost effective way to display a fireworks show during the Chinese New Year festival by spraying molten metal onto and alongside a wall, an incredibly beautiful, yet dangerous feat to pull off. This process is referred to as “dashuhua” (pronounced “dash-ooh-wah”). The metal is 1600 degrees Celsius which means it is literally in a liquified state. The dashuhua master traditionally wears a straw hat and sheepskin coat for protection. There is currently only 1 dashuhua master left in the world, a person who is a 14th generational master. This master has 2 daughters, neither of whom want to learn the craft, so theoretically, after this master passes away, the tradition will die out

Highest Elevation at Which People Live

In La Rinconada, Peru, the entire village of La Rinconada lives as high as those who make base camp on Mt. Everest before attempting to scale its peak. When Spanish settlers first landed in La Rinconada, most lost their infant children shortly after birth because oxygen levels are half of what they are in comparison to most other places on Earth. The reason people stayed and continue to stay in La Rinconada is because of the gold which can be extracted from the nearby mountain ranges. La Rinconada is the absolute highest elevation at which humans can live, as anything considerably higher would cause organ failure which is often quick and difficult to detect by oneself resulting in death in many cases

Elon Musk’s Innovative Tesla Battery

Tesla-Model-3

Tesla vehicles use approximately 8000 small cell batteries close to the size of a double A (AA) battery, only slightly larger with a length of 65 millimeters and a width of 18 millimeters. Tesla originally used this battery size because of its wide abundance but will be switching to a slightly larger size with a length of 70 mm and a width of 21 mm when their gigafactory is complete. Tesla claims that these new batteries will be the best and cheapest option in the world. Competitor manufacturers use different kinds of batteries than Tesla because of their belief in how the technology works and how efficient it can be

Ancient Stained Glass Manufacturing

The manufacturing of stained glass is an ancient technology which dates back so far that the ancient Egyptians knew how to do it 2000 years before the birth of Jesus Christ. Medieval Europe inherited this form of technology but did not invent it as is common belief. Deep, rich blue glass was very difficult to make and therefore needed to be imported from southern Italy. The deep blues which the Chartres Cathedral in Chartres, France is so famous for can historically be traced through documentation to fragments coming from the Byzantine Empire as well as the Roman Empire. These imports were melted down and used to create new glass. Most colors and dyes came from the natural world in the forms of roots, berries, barks, leaves, minerals, and crushed insects, but the most prized colors were imported into Europe from the east, specifically India and China using Ottoman trade routes. The simple luck of geography made Venice, Italy an incredibly wealthy city as it acted as a nexus between the east and west. The blue hue referred to as “ultramarine” was the most expensive color to acquire and therefore it was almost always saved for depictions of the Virgin Mary, typically in her cloak or some other form of clothing, as Mary was depicted as the focal point of every painting she appeared within. Ultra Marine came from the mineral of lapis lazuli and when it was ground up into powder, some parts would inevitably become smaller than others which allowed these particles to reflect more light and provide a deeper, richer color to work with and appreciate. Vermillion Red was almost as precious as ultramarine, and has been used in Europe for hundreds of years in various illuminated manuscripts. Made from the mineral cinnabar, vermillion was adopted in places outside of Europe like meso-America for painting, India for bindi dots, and China to create lacquerware

Medieval Age Armor Of Impoverished Soldiers 

Medival-armor

Poorer soldiers who could not afford armor or chainmail would use a garment referred to as a “gambeson” which consisted of layers of cloth with thick wool sandwiched in between more layers of cloth, similar to the modern advent of Kevlar which is tightly woven layers stacked on top of eachother. The gambeson was sewen extremely tight making it flexible but also somewhat resistant to blows. It wasn’t as effective as armor and chainmail but it did offer moderate protection. Those who could afford it would have covered their gambeson with chainmail as an added layer of protection

Quartz Veins Filled With Gold

The California gold rush during the 1840’s caused hundreds of thousands of people to engage in mass migration. After any gold laying upon the surface had been excavated, miners dug into the ground to continue in their search. Miners surveyed for quartz veins as quartz virtually always meant that gold was nearby. Most gold sinks into the Earth’s core with other heavy metals like iron but occasionally, some gold remains with lighter minerals like quartz which is why gold can often be found imbedded inside of quartz. The reason gold nestles in with quartz is because earthquakes cause natural fissures to occur which provide pathways for superheated water containing minerals. This mineral packed water then cools down and the minerals carried within the flooded cracks left from the fissures, crystallize
