The use of a pearl tincture, created from the inherent essence of this rare gem, can stabilize a transmutation potion. It is a crucial component for potions meant to modify living flesh for any period of time. Pearl tinctures can be created in a number of ways. The purest essences take time and patience, not unlike the creation of a pearl from a grain of sand. Note: Pounding a pearl with a fist-sized rock is not efficacious. I like the word efficacious. Gadris uses it often and it has stuck with me. Efficacious. Yes! This may work! I'll have a tincture in no time!
