All RAKU pots and vessels ARE NOT FOOD SAFE and the clay is very porous, so it will leak. If you have a vase that you want to put cut flowers and water in, line it with plastic first. They are strictly to be viewed and collect dust. Also never leave them in the sunlight or the glorious colours will fade. Over time, oxidation takes place and the colours will become dull, unless the potter has treated them with a clear wax.
