If you get a good hot throw in the melter, you could melt them down and make clamshells or tarts with the wax. IF you get a good hot throw in the melter so you know it isn't your fragrance that is the problem, you could melt down one jar, reheat the wax to 180 or whatever you use and add fragrance oil so you are up to, say, 7%. See how that goes. I've melted mine in a low temp oven.
