How Flames Were Artificially Produced for Opera Productions During the 18th Century

Leave a comment

During the 18th century within opera and theater productions, stage doors which would lead a character to Hell achieved simulating the flames of Hell with brandy which would be placed into a container and lit on fire due to the fact that during the period, brandy was the brightest glowing flame available because of it’s high alcohol content. Once the brandy was burning bright, a powder referred to as “lycopodium” was blown across the flames to create an intense illumination, creating a fireball of sorts. It was in truth a very dangerous special effect to achieve because of the wooden sets, the actors involved, and the enclosure of the theatre itself. Most of those who performed the pyrotechnics for operas and plays during this period were ex-military, often soldiers who understood how these chemicals worked in depth as rocket technology was at the cutting edge of warfare during the era

Tudor Period Mining and Metal Smelting

Leave a comment

During the Tudor period, lead was utilized to build roofs and windows because it was easily mailable and resistive to corrosion. Farmers would mine for lead during the summer months when their crops did not need tending to in order to generate additional income. Mining during the summer months could earn an extra £5.00 which equates to £25,000 as of 2012 when accounting for inflation. Entire families often worked within the mines because 50 barrels worth of ore and soil would be extracted per day to meet the quota of what was required to be profitable. Smelting involved the use of white coal which is effectively dried wood from a kiln and was always setup upon windy hilltops or mountains because the wind would cause the fire blaze with more intensity therefore reaching higher overall temperatures. The best wood to make white coal is oak. Kilns must be airtight, so gaps were filled with clay. Knowing a kiln to be airtight was easily verifiable by searching for smoke as if smoke only came out of only the front entrance, the kiln was considered airtight. Ore was smashed into small pieces to help it smelt more rapidly which yielded approximately an 80% return upon investment. Metals were then refined using a secondary kiln, and smelted to remove any ash or impurities. The first burn removes ore from the rock, and the second burn removes impurities with the main impurity being sulphur. Molds were constructed using sand and wood to create divots which allowed the ore to be molded into blocks much the same as a modern day bar of gold. The sand gives the mold an indentation which archeologists use to identify Medieval bars of smelted ore

The Etymology of the Christian Demon Name “Lucifer”

Leave a comment

The name “Lucifer” in reference to Satan from the Christian faith is derived from the Latin terms, “lucem” and “ferri”, which mean “light” and “bearer”. Lucifer, and from that Satan, holds resemblance to Prometheus, a Greek god who is credited with creating the human race by spawning human beings from clay. Prometheus is also credited with providing civilization with the gift of fire, which resulted in him being punished when caught by having his liver eaten by an eagle by day and then growing back again at night, repeating this cycle ad infinitum

Mid 20th Century Malaysian Head Hunters

1 Comment

The Iban people of Sarawak, Malaysia practiced head hunting until the middle of the 20th century. Iban warriors were infamous within the region for decapitating their conquered victims to save the head as a trophy. Heads were strung and hung together at the top of the loadbearing posts of the long houses which the Iban continue to live in during the modern day, housing up to 25 families in a single building. Every month the Iban light small candles or fires below the hanging skulls to keep them warm because if they do not, they believe the spirits of the vanquished enemies will come back to haunt the dreams of the Iban. This practice was used as a right of passage and milestone mark for young Iban men throughout history, with young warriors forced to kill an enemy within the jungle and then bring the head of that enemy back to their home in order to bless it for everyone in the community. It was also common practice for Iban women to carry these skulls up and down the veranda of the longhouse to signify celebration for the bravery of the males of their family

Technology Provided by the Iron Age

Leave a comment

Iron was favored over bronze throughout history because it could be formed into thin and detailed structures which could not be achieved when casting bronze. This is important because it meant that iron blades could be worked and therefore sharpened to a much more refined degree than bronze which was brittle. Iron is also more readily found, a metal which could be found locally around the world and did not depend upon an immense, trading network. By 400 B.C., iron tools and iron objects became ubiquitous throughout various civilizations with the effects of this new technology felt upon the cutting edge of agricultural technology. Iron is more practical than bronze as bronze needs to be melted down and recast if broken in opposition to iron which could be taken to a fire, hit with a hard object, and repaired to the point at which it becomes functional once again. These aspects helped iron to gain favor worldwide as the metal of choice for building and advancing society. As the Iron Age progressed, knowledge about where iron deposits are found became better understood with more and more iron becoming available upon the open market. This is important because the more readily available a particular type of artifact is, the younger the item typically presents as. As time progressed, iron became akin to plastic of the modern day, being cost effective and readily available to manufacture virtually anywhere. Iron tipped wooden plows allowed for more difficult soils to be farmed, which meant that more land could be cultivated making iron truly an agricultural and commercial revolution in the ancient world. Despite lasting for a period of 1000 years, the Bronze Age was quickly replaced with the more effective and efficient Iron Age. The issue of total replacement is complicated as bronze was not only used for tool making, it also helped to create an elite class and was used for spiritual and ceremonial objects as well as visual displays of prestige and wealth. Iron tools several hundred years later, failed to achieve the same intrinsic value within society that bronze once had as it was less rare and precious and therefore less valuable. Iron tools however were highly practical unlike their bronze counterparts, a feature which plagued agriculture and society as a whole

The Benefits of Methanol as an Energy Resource

Leave a comment

Methanol is the simplest alcohol to make and is the most probable choice fuel for future Mars missions. Ethanol only requires water and carbon. Methanol is colloquially referred to as “wood alcohol” and/or “natural gas”. Professional racing car drivers prefer methanol as a fuel source due to the fact that it’s much less likely to catch fire after a crash. Methanol burns incredibly clean in comparison to gasoline and methanol costs 33% of what gasoline costs to manufacture and distribute
