Mendocino College Raku firings start with glazing outdoors as the gas in the kiln is lit. The pieces are then loaded into the kiln until the temperature rises to about 1800 degrees F, then we peer through the spy hole to see if the cone has changed. When the cone looks like it has melted, it is time to take to take the pieces out of the kiln. For safety, we wear protective clothing made from 100% cotton, closed-toe shoes, heat resistant gloves/mask, and use long-handled steel tongs. Items are then removed from the kiln and placed into a covered metal container filled with a combustible material such like newspaper and sawdust to provide a reducing atmosphere for the glaze. After the shredded newspaper begins to ignite, the lid is placed on to remove the oxygen, extinguishing the flames. Once the pottery is removed from the can, it is usually left out to cool, then cleaned with Comet Bleach Powder. …show more content…
The slightest variation in thickness causes the glaze to change color. Potters often use special formulas to make a glaze containing high copper contents which create a rainbow of colors. Carbon is trapped in the glaze which creates a crackle effect as the piece cools down. When a copper based glaze is used, the reduction can cause red and cuprous lusters. White crackle glazes have black lines on the surface to give it a cracked appearance. Black matte surfaces are created in unglazed areas due to the smoke from the fire. It is during this phase where all of the magic happens and the colors start to form as the flames begin to remove the oxygen from the glaze changing its chemical
The Kansas City Gun Experiment was a study that took place between 1992 and 1993. The goal of the study was to examine if increased police patrol in a “hot spot” of the city would help to reduce the amount of gun-related crime. The data collected by the research team was solely quantitative as it mainly consisted of statistics and other data numerical in nature of the increase/decrease of gun violence in these beats. After the twenty-nine week period of the study, the experiment’s findings showed that an increase in police patrol, as well as seizure of illegally carried guns, did help to eliminate gun-related crimes.
The purpose of the projectile lab is to test the validity of the law of conservation of energy. The application of this law to our everyday lives is a surprisingly complicated process. Conservation of energy states that energy cannot be created or destroyed, but that it can be transferred from one form to another. Consider the projectile lab from document A that this essay is based upon. In an ideal experiment, the projectile is isolated from everything except the gravitational field. In this case, the only force acting on the particle is gravity and there are only two forms of energy that are of interest: the energy of the particle due to its motion (defined as kinetic
The materials of black tattoo pigments are Iron Oxide (Fe3O4), Iron Oxide (FeO), Carbon, and logwood. The black pigment is made from magnetite crystals, powdered jet, wustite, bone black and amorphous carbon from combustion. Logwood is a heartwood extract found in Central America.
The old saying “The South never dies” appears to be all but accurate in William Faulkner’s The Sound and the Fury. Each member of the Compson Family is practically a contrary of old southern ideals and beliefs. Caddy’s promiscuity, Benjy’s mental disability, Jason’s vulgar attitude towards his family, Quentin’s crooked obsession with Caddy, Ms. Quentin’s rebellious attitude due to her own upbringing, and Mrs. Compson’s ability to see her children as punishments from God; they all diverge from an idyllic well-ordered Southern family. Mr. Compson was the only member who managed to held on to his Southern Morality for the most part, only straying from the norm after the death of his son, Quentin. Each character in their own way depicts how old Southern ideals of gentility have begun and continue to dissolve.
9). Toselli noted that Egyptian women used henna to color their nails (2009). The most notable color used to paint their nails was red. However, the color red was reserved for women of power. One example of such women, is Cleopatra, who “…favored a deep rust red” (Toselli, p.9). Women of lower stations “…were permitted only pale hues” (Toselli, p.9). Pales hues refers to light colors. Over the years different ingredients were utilized to create nail stain, varnish all otherwise known as nail polish. According to Toselli, the mixture of Arabic gum, egg whites, gelatin, and beeswax was used by the Chinese. “They also used a mixture of pulped rose for color, or orchid and impatiens petals combined with alum, which, when applied to mails overnight, left a pinkish, reddish stain” (Toselli, p.9). Eventually, ingredients included: scented red oils, powders and creams. It was by accident that it was discovered that “…boiling nitrocellulose made it soluble in organic
In Firearms: A Global History to 1700, Kenneth Chase investigates why Europe perfected firearms when the Chinese invented them. Kenneth Chase is an attorney at law who received his PhD in East Asian Languages and Civilizations from Harvard University. He uses primary sources in the form of texts and paintings as well as secondary sources in this monograph to trace the origin and spread of firearms. He also uses these sources to characterize militaries and determine why they used or did not use firearms. Chase dismisses the notion that the discrepancy between Eastern and Western firearms development was the result of cultural aversion. If anything, he argues that Europeans were more averse to firearms due to its association to Satan and a general
Despite the justifications government have provided, they still fail to justify the actual treatment that Japanese Canadians themselves endured during the duration of the second world war. Evacuation entailed all Japanese Canadians to be move into a “protected zone” 100-miles away from the west coast, no more than 24 hours notice was given to the Japanese citizens about the evacuation. Consequently, this meant that the Japanese citizens did not have enough time to make arrangements for, to secure, or sell the property they could not take with them. Not to mention the government already confiscated their fishing boats and other property they deemed to be dangerous, such as radios, cameras, and firearms. The government assured Japanese Canadians
Colour is the light reflected off of objects and is categorized by hue, value and intensity. Hue is the name of the colour shown, value is how light or dark it is, and intensity is how bright or dull it is. The main hue’s shown in this painting are red, white and gold. The colour red on the people’s clothes really showcases the people and makes them the main focus of the painting. Specifically, Christ and his disciple’s in the foreground of the painting are really showcased through the colour of their clothing. Also, the white contrasts with the red, showcasing the white tablecloth, the white pillars in the background, the white apron around Christ’s waist, and the dog sitting in the front. The value of the colours throughout the art piece are all very dark, making the piece very gloomy and intense. The dark colours, as well as the darkness coming in from both sides of the painting make the painting very expressive. The deep red colour really captures the expression and meaning behind the washing of the disciples’ feet. The colours overall are not very vibrant, but very dull, which also showcases the expression around the painting and how intense the scene is. Therefore, through the formal element of colour, the artist is trying to express the realism of the
In class, we watched the documentary titled, “Sound and Fury.” The video mostly focused around two brothers (one hearing and one Deaf) and their families, whom were a mixture of hearing and Deaf. The first family consisted of the hearing parents, Mari and Chris Artinian, and their two twin boys, one of whom was Deaf (Peter Artinian Jr.). The next family was made up of two Deaf parents Nita and Peter Artinian Sr., along with oldest child Heather, whom is Deaf and her two brothers. The two grandparents of both father’s Peter and were also included in the film.
The Sound and the Fury is a story of sometimes unclear focus. From section to section we listen to three brothers: Benjy, Quintin and Jason, discuss their lives. We discover the inner workings of their home lives. The narratives disclose that their mother, Caroline Compson is a neglectful, hypochondriac. Mrs. Compson is shown to be a very self centered woman who really doesn't harbor any affection for her family and by this lack sends some of them to find mothering from a different source. “ How can I control any of them when you have always taught them to have no respect for me and my wishes I know you look down on my people but is that any reason for teaching my children my own children I suffered for to have no respect.” (Faulkner, 61) We meet Mr. Compson, the father, who is shown to love his children dearly, though in the case of some does not always like them all. He just happens to be an alcoholic, “Father will be dead in a year they say if he doesn't stop drinking and he wont stop he cant stop....” (Faulkner, 79) who is eventually killed by his addictions. Also introduced and discussed are the various household staff members whom the brothers love as if they were family. The brothers discuss horrors and anxieties that they are dealing with in their personal lives. Benjy's horrors of being unable to communicate, being tormented by his brother, Jason, and eventually being castrated due to a misunderstanding cover section one. In section two, Quintin takes his turn to share the anxieties that time and sexuality (among other things) cause him. The last of the brothers narrations, that of Jason, delve into the cruelty he imparts on others, as well as the bitterness and struggles he rapidly accumulates in raising his niece. All o...
Shell shock is defined as a psychological condition presumed to be caused by a traumatic experience occurring in warfare, however, there is still not an agreed cause of shell shock. Shell shock has been given many names over the years such as “war neurosis” and “neurasthenia”, however, today it is usually referred to as PTSD (post-traumatic stress disorder) due to the fact that shells played very little part in the cause of shell shock. During the early stages of the war, it was believed that shell shock was caused by a physical injury to the nervous system. Denis Winter (p.136;1988) states that “80% of shell-shocked men…had a previous psychiatric record.” Winter also believed that the explosion of shells was the primary cause of shell shock (p.130;1988).
World War I marked the true end of the Victorian times and replaced its imperialism, peace, and female hysteria with gas warfare, mass bloodshed, and shell shock. Dr. Charles S. Myers, a British psychologist, was the first to write a paper on shell shock in 1915. By writing and publishing this paper Myers brought shell shock into the spotlight of war psychiatry diagnosis. Shell shock, also known as war neurosis, was by no means a new illness, the first signs of shell shock popped up during the Crimean War in 1845 with Crimean fever. One captain with Crimean fever reported “pains in all the limbs, clammy sweats, parched tongue, irritable heart, dizziness, headache and diarrhea, while being utterly unnerved and agitated violently by the merest

The lantaka is fueled with water and calcium carbide, which together releases acetylene gas and produces an explosion. The making and firing of lantaka is so popular in Kidapawan, North Cotabato that the province holds the Kanyong Kawayan Festival (Bamboo Canon Festival) to celebrate Christmas and the New Year.
