I'm not certain that the word you're using, " potion ", is the word you were looking for. The standard definition of a potion is " a liquid with healing, magical, or poisonous properties ."
So making a musical potion makes no sense. Did you perhaps mean a " magical potion "? And if that is the case, then what sort of magical potion were you making? What purpose is it supposed to perform?
You also said you " enchanted markers to like candle colors ". Again this doesn't make a lot of sense as written. Are you saying you enchanted something like a Magic Marker so that they had the same color correspondences as candles? Or did you mean that you enchanted them and then used them instead of candles?
Or perhaps are you creating a potion as it talks about in the game Minecraft? Because there are differences between magic in role-playing games and real magic.
Please clarify your initial post if you would.
