Oh my goodness, is grandma baking one of her famous apple pies?
The wood wicks are untreated wood to eliminate the chemicals. This does require that you watch them for the first 20 to 30 minutes to make sure they stay lit. Once you have made it past the first 30 minutes, continue to burn until the wax has melted to each side and down about a 1/4". If you do this, you will have a great candle experience. If you don't, you may cuss me and I don't want you to cuss me.
