OK Amber, I followed your advice on the water bath. I heated a pan of water, put a baked beans tin with 3 candles into it and waited (for what seemed a week). Then I poured the whole melted mess into the glass jar to about a third full. Then I spent the next hour fishing up the wicks and making a mess inside the jars. Now I ended up with 2 wicks showing above the wax, so tommorrow when it's all hardened, I'll light them and see if the heat will clean up the inside of the jar. Not a very successful start to this project.
