Introduction
Today, candles are made not only for lighting purposes but for many other uses such as home décor, novelty collections, as fixtures for big occasions (weddings, baptismal , etc.), and as scented varieties for aromatherapy. Candles are made from different types of waxes and oils. Cooking oil is a major kitchen item in Filipino households. It is also used substantially in fast-food outlets, where it is used in different stages of food preparations. Ordinarily, used cooking oil is discarded. This waste oil pollutes and clogs canals and sewerage systems. The sound of cooking oil as the prime material for making candles may

Because of its low melting and re-solidifying points as observed by DSC (~20°C melting onset,39.0°C melting peak, and 22.0°C re-solidification peak), soft soy wax melted extensively, causing the wick to be drowned during the burning of container-type candles. For taper- and narrower pillar type candles, the liquid wax dripping from the candle did not solidify fast enough to prevent the liquid wax from running on to the bench. These problems stimulated us to evaluate fully hydrogenated soybean oil (referred to as hard soy wax, ~0 IV) for candle application. These candles were hard and shiny with no surface greasiness a tall. Furthermore, the melting and re-solidification properties were improved.DSC analysis of hard soy wax indicated two melting peaks at 52.8 and 63.0°C, and a solidification peak at 46.5°C. Compared to a commercial paraffin candle (with minor and major melting peaks at 40.6 and 59.0°C, respectively, and a re-solidification peak at 49.7°C), the melting and re- solidification properties of hard soy wax were highly acceptable. However, the candles had an unacceptably brittle texture and they did not fully melt across the candle surface; therefore, they were not fully consumed during combustion (even with taper candles).To improve

Hanukkah, being one of the most well-known ceremonies to use candles, is actually called the Jewish Festival of Lights. The main purpose of this ceremony is the actual lighting of the candles. Candles had been used as early as 165 B.C. for the purpose of Hanukkah. Candles made from beeswax were the most popular among religious ceremonies, but they were also one of the more expensive candles. Because they were more expensive, the wealthy were among the few who could afford to burn beeswax candles for personal use.
Candles are a convenient way of providing light and heat when no electricity is available. They are normally made from paraffin wax with a wick in the middle. Candles can also be made from soy wax or other plant wax, animal fat or bee wax. Wax acts as a fuel to keep the candle burning. The wick has to be an absorbent twine with
In this experiment, the signal generator was set so that the frequency meter showed a reading of 1,803 Hz. The microphone was moved to a distance from the speaker so that the oscilloscope displayed a straight diagonal line. This position was of the microphone was recorded as the initial position, or beginning of a wavelength. The microphone was then moved farther in the same direction until the oscilloscope displays the same horizontal line. This position was recorded as final position, or the end of the wavelength. The distance between the two positions represents one wavelength for this frequency. This was repeated for frequencies of 2,402 Hz, 3,002, Hz, 3,602 Hz, and 4,201 Hz.
The candle maker’s job helped the rich and poor. Since, some peasants couldn’t afford beeswax candles they bought tallow candles which were made out of animal fat. The animal fat burned faster than the beeswax candles, and had a smokier flame than beeswax candles. Which is why the tallow candles were cheaper. Rich people usually bought beeswax candles because they lasted longer and were nicer than the tallow candles. Also, tallow candles gave off a foul stench.
This article focuses on the Revolutionary period of Colonial Williamsburg when candles were a primary light source in homes. At this time in history there were four primary substances used in making candles, spermaceti, tallow, beeswax, and myrtle or bayberry wax. The three latter substances were produced in Virginia. Methods of making these candles and how they were shaped are described in the article.
The candles normally used are Biosun ear candles, which are made by hand today using the traditional recipe incorporating
Millhouse Candles has an article on their website with a timeline of candle history. “A Short History of Candles” outlines this history from 3000 BC to present. This outline is broken up into four periods, 3000 to 1 BC, 1 BC to 1500 AD, 1500 AD to 1799 AD, and 1800 AD to present. Each of these time periods contain facts about the cultures that were making candles, the materials used for the candles within the periods and a technological advancement for that time.

The “Coolest” Experiment Ever is a science fair project to determine whether or not mints have a cooling effect or is it just a sensation. The predicted outcome of the experiment is that if we add mints to a hot glass of water, it will cool down more than the glass without mints. The reason being is because mints contain menthol, a substance that melts just above room temperature. It triggers a cold-sensitive TRPM8 receptor which produces a familiar cooling effect. The basic procedures of this experiment is to fill two glasses with hot water, and add five mints every five minutes. After every trial, check the temperature using a thermometer. Record all the observations you have made with a critical eye. The predicted outcome of the experiment
The fun filled journey you take when you burn a Prize Candle speaks to your sense of sight, smell & touch.
For my Scican project, I wanted to make sure that I had a topic that was unique and interesting. Choosing a topic could be seen as the most important part of this entire assignment. This one topic dictates your entire project, so you had better not choose a lousy one. I fiddled around with multiple ideas for a while, because lousy topic means lousy assignment. But what could I do? The classic volcano? Too mainstream. Environmental issues? Nah… Curing cancer? Too much work, I am only bronze after all. In the end, I chose psychology.
I wanted to do this experiment I like the idea of burning candles. It seems that just about every
1: Gather all the materials needed for the experiment (a meter tape, a ramp, 2 carts with wheels and without wheels, a rubbermat, 5-gram masses, tape, a triple beam balance, a calculator, and 2 other people to help you [Person 1 and Person 2]).
At one time, scented candles were a rare luxury to be enjoyed only by the rich while the rest of us made do with the ordinary white candles during power cuts and at Christmas time. However, that has all changed, and an endless variety of fragrances are filling our homes and relaxing us. Candles are just one of these sources of wonderful smells, but they are also a very popular source, partially because of the number of different forms in which they are available but also because they look so good with their burning flame.
