Many people have never heard of the 6-12-6 method of candle burning even though Harry Middleton Hyatt recorded it in his work and stated that it was the most popular form of burning candles. Today the practice is nearly extinct. I would like for people to return to it and embrace it once more, if possible.
One of the reasons why it fell out of favor is because the working conditions of people changed. In the past, many people worked day jobs, temp positions and seasonal work. This meant that for many days to weeks people may have been off before working again. So people had a bit more time to burn candles. Back then the majority of women remained housewives and so they too were able to work this routine into their busy schedules.
The 6-12-6 method of candle burning is quite easy to accomplish. For this you will need preferably a free standing jumbo pillar in the proper color. If you are in a pinch you can substitute any candle you may have and if you don't have the proper color you can substitute with white. Remember that before colored candles were popular people primarily only had access to white candles and so white can be used for anything.
So you take your candle and you mark it, bless it, pray over it, dress it with oils, herbs, powders, etc., however you fix you candles, and you set it to burn. At 6am you will light it, state your petition and let it burn for 15 minutes and then pinch it out. At 12 noon you will light it again, state your petition and allow it to burn for 15 minutes and then pinch it out. Finally, at 6pm you will light the candle, state your petition and let it burn for 15 minutes and then pinch it out. You can do this on a Monday, Wednesday or Friday, letting it rest Tuesday and Thursday, until the candle is extinguished. Alternatively, you can start on a day of the week that corresponds to your situation and then work the candle each day afterward until the candle is extinguished. Hyatt did record one woman who gave a slight variance to the ritual, saying to burn the candle at 7-12-7. However, most of the informants stated it was 6-12-6. If you want to incorporate working with the clock into your work then you can use 6:30-12:30-6:30, or when the hands of the clock are moving upwards to draw stuff to you or 6-12-6, when the hands of the clock are moving downwards to remove stuff. However, traditionally the method was 6-12-6 regardless of the nature of the work being done.
The above is a very traditional method of candle burning that I would like people to return to if possible. I know that in today's busy world that many people simply do not have the time for such and are not home during the day. However, if you are retired, on vacation, have some sick time, in-between jobs, etc., give it a try.
