Hello! I was wondering if I did a spell either slippery elm right and also how to dispose of the ashes left over? How I did the spell was I poured a small amount of slippery elm powder in to my cast iron cauldron, then I tied a knot in to a nit of yellow thread then lit the slippery elm powder and put the thread on to the lit powder it was lit a a small while then went out now there just some ash in the cauldron an I'm not sure of how's best to dispose of it?
