Directions: Immerse 150ml glass bottle or 750ml PLA bottle in very warm water (gradually warm glass bottle first under the tap to avoid breakage). Wait several minutes for a little melting to occur for use. To melt the full contents of the 750ml bottle you may have to leave for 15 minutes depending on temperature and repeat with freshly warmed water if need be. This will not damage the oil in any way.
