Most people don't know how to burn and most really don't care as long as scent throw is there! No matter how many times I tell my friends and family how to burn candle, doesn't matter who made it, they all look the same! Hang ups and mushrooms and some sooting. I just recently switched my friends over to soy....hate to see what my jars looks like. I'm hoping they followed my instructions! You may produce a perfect burning candle, but in the hands of a customer, it all changes! Saltbox Pantry
