NO
yes but be VERY careful.
No if the candle not lit it probably won't melt
Yes, boiling water can melt candle wax. The heat from the boiling water will transfer to the candle wax and cause it to melt.
A regular indoors candle will. Best to use tea lights or another contained candle so that it doesn't melt all over. I've been looking all over for candles that will resist sun light, but so far no luck.
Yes, save up all the drips, and candle ends, melt them over a gentle heat and make new candles.
The time it takes for a candle to melt depends on factors such as the type of wax, size of the candle, and environmental conditions like temperature. Typically, small candles can melt in a few hours, while larger candles can take several hours to melt completely.
I've melted (and burnt) sugar just by putting it over the candle.
It matters how big the candle is then you do how fast the fire burns the candle.
Wax.
no
candle wax
To remove candle was from brick pavers, you will need old towels and an iron. Place a towel over the candle wax, run your heated iron over the towel. This will melt the wax, which will be absorbed into the towel.
