Directions are listed on refill kit and very easy to follow. Dough bowls should only be refilled twice after the initial burn.
Please note refill kits are only to be used in dough bowls that previously had a candle in it. Dough bowls have to be treated before a candle can be put in them. For safety reasons please do not put refill kit in any glass jars or anything other than previously purchased dough bowl candle from us**
