Cut the soap into 1"/2.5cm chunks and place in Pyrex glass cup/jug or bowl. Melt the soap in the microwave for 30 seconds and stir. If it is not completely melted, put it back on for 10 second increments, until fully melted; stirring each time.
Add the lime zest and the coconut soap fragrance oil. Mix well.
Pour into the silicone mold.
Lightly sprinkle with more lime zest on top of the liquid soap mixture. (Optional.)
Mist lightly with rubbing alcohol to help reduce bubbles.
Leave to set for 3-4 hours.
Remove from mold and use the straight scraper to cut the soap into 2"/5cm bars.
