Problem Statement

What is the procedure of a taper combustion? Does adding dye impact a tapers firing rate? ? Do coloured tapers burn quicker because the added dyes? Colored tapers are popular in places, their pleasant aromas, loosen uping traits and cosmetic qualities are merely a few grounds why people love them. I myself a candle lover have noticed that different tapers burn at different velocities. Which lead me to oppugn, if the dyes used to colourise the tapers affects its firing velocity?

Background Research:

To to the full grok if utilizing dye to colourise a candle affects its combustion rate, it is indispensable to analyze and grok the taper itself along with its combustion procedure.

A taper is a piece of tallow or wax with an embedded wick. A taper is made by paraffin wax which comes from rough oil. When exposed to a temperature of 380 grades or higher paraffin automatically combusts. The wick is composed of porous spiral.

The candle combustion procedure

The runing procedure of a taper is simple ; foremost the wick is lit, which starts the fires journey down the wick were will finally make the wax. Consequently, the heat of the heat melts the shaped wax into a liquid. Subsequently the wick absorbs the freshly melted liquid and uses it to fuel the fire. Therefore it is the liquid wax of the taper that fuels the fire, leting it to go on combustion.

Experimental design

The experiment will dwell of firing a assortment of five coloured birthday tapers and entering the velocity at which each taper Burnss.


The experimental will be performed on my dining room tabular array. Each taper will be separately placed in a candle holder, following both the taper and the candle holder will be placed in a tea cup, and so the taper will be illuminated and timed.

    1 ) First, gather all the needful supplies,

  • A assortment of five coloured birthday tapers
  • Candle igniter
  • Stop ticker
  • Candle holder
  • Tea cup
  • Scissorss
  • Marker
  • Metric Ruler
  • Data sheet
  • 2. Each taper will be measured and marked one inch from its underside.

    3. The white taper will be illuminated and timed foremost.

    4. The white tapers firing clip will so be recorded.

    5. The anterior stairss will be repeated for each of the staying tapers separately.

    6. Following the completion of the candle combustion procedure, the recorded consequences will be compared and a graph stand foring the consequences will be created


  1. Mugwump
  2. The colour of the taper will stand for the experiments independent variable.

  3. Dependant
  4. The rate at which each taper Burnss will be the experiments dependent variable.

  5. Controls
  6. The followers will be the controlled variables of the experiment.

  7. The mensural distance of the grade in the tapers.
  8. The trade name of the tapers will be the same.
  9. The combustion of the tapers will be performed in the same clip and topographic point.
  10. The temperature of the room will stay the same while each taper Burnss.
  11. Threat decrease to internal cogency

    The undermentioned stairss were taken in order To minimise mistake during the experiment,

  12. the tapers will all be the same trade name
  13. the tapers will be measured and marked to guarantee all tapers are the same size
  14. Each taper will be placed in a candle holder and so in a tea cup in order to extinguish unexpected elements


The velocity at which a taper Burns is non affected by the dyes used to give the taper its colour.

To develop this hypothesis, the research was carefully considered, The National Candle Association explains that dyes used in candle colouring are dissolved and assorted with the wax ‘s oil. Since the added dyes do non choke off the fibres of the wick, the tapers firing ability is minimally affected. As a consequence tapers colored with dye should fire at the same rate. These researched facts lead to the decision that added dyes do non impact a tapers firing rate.

Explain the procedure of informations aggregation

The candle combustion procedure research was collected through


  1. Time will be calculated with a timer
  2. Candles will be measured with a metric swayer.

Pre experiment anticipations

Experiment Consequences

  1. Yellow Candle: 8 proceedingss 24 seconds
  2. Blue Candle: 8 proceedingss 54 seconds
  3. White Candle: 9 proceedingss 4 seconds
  4. Pink Candle: 9 proceedingss 20 seconds
  5. Green Candle: 9 proceedingss 22 seconds

Written Results

The consequences of the experiment resulted in the xanthous taper reached its grade the fastest, and the green taper was the slowest combustion taper. The tapers burned in the undermentioned order get downing with the fastest: yellow, blue, white, pink and last green. The graph shows the rate of the tapers firing with 8 proceedingss being the fast and 9 proceedingss being the slowest. The graph besides indicates that the dye does n’t impact the velocity at which a taper burns. The white which is the lightest colour was the 3rd fastest taper to make the grade, non the first as antecedently stated. Blue the darkest taper finished 2nd fastest.


The hypothesis stated “ The velocity at which a taper Burns is non affected by the dyes used to give the taper its colour ” . The consequences of the experiment supported the hypothesis and proved that the dyes used to colourise tapers have small or no affect on the candle combustion rate.


The consequences of the experiment conclude that candles do non fire at the same rate besides they do non fire harmonizing to the lightest to darkest colored. The consequences of the experiment confirm that the dependant and independent variables have no relationship. The information from the experiment answered the research inquiry: “ Does the added colour in a taper affect the tapers firing rate ” ? The experiment concluded that adding colour to a taper does non impact its combustion rate.


Summary of the experiment

The stated job: “ Does adding colour to a candle affect its combustion rate? ” A assortment of five coloured tapers, all of the tapers were the same size, trade name and tested under the same conditions. The coloured tapers used to carry on the experiment were xanthous, bluish, tap, white and green. The tapers were all measured one inch from the underside to guarantee the combustion clip be indistinguishable. Next the tapers were illuminated and the timer was started. The times were so recorded. Following the experiment the information was so comparison and the consequences confirmed that the added dyes in tapers do non impact its combustion clip.
