Unless the glass rod is heated to very high temperatures, nothing will happen except that it will be covered soot from the incomplete burning of the candle.

Does the wax affect how the candle burn?
I. Statement of Purpose and Hypothesis: My topic was about burning candles. I wanted to find out what color candle would burn the fastest. My hypothesis stated that, if I burned five candles, one red, one white, one yellow, one purple, and one blue, then the white one would burn the fastest. II. Methodology I tested my hypothesis by burning five candles. The materials that I used were a ruler, stop watch, black maker, candles, candle holders, and matches. The variables that were kept the same were the candle's brand, when we started to burn them, the length and width of the candle, room temperature, and distance between the candles. The only thing that was different was that the candles were different colors. To carry out my project I first set up the candles four inches apart. Then I marked a line one inch down form the wick on each candle. Then I lit them all at once. Next, I started timing how long it took each to burn. I stopped timing when the mark on each candle was gone. Finally, I recorded my data. III. Analysis of Data: The white candle didn't burn the fastest. The fastest burning candle was the yellow one which took twenty-two minutes and twenty seconds, then red which took twenty- four minutes and thirty seconds, then blue which took twenty-five minutes and eleven seconds, then the white candle which took twenty-five minutes and twenty seconds, and then the purple one which took twenty-six minutes and one second. IV. Summary and Conclusion: I found out that the fastest burning candle was the yellow one. Therefore, I reject my hypothesis which stated that the white one would burn the fastest. If I could do this experiment again I would make a few changes. I would make the mark on the candle two inches down instead of one inch down. I would also try other brands and colors of candles. V. Application: I learned that, if I ever wanted candles that burn fast, then I should get light colored candles because they burn the fastest. Color really has an effect on burning candles
