porcelain tiles are solid with the back of the tile and the front the same material... I have had good luck outside with the glazed tiles I used for my mothers house.. they have spent 35 years as the tiles on the front poarch.. and glued together to make planters.. without cracking...
these photos are from the Italian bakery a door down from me... although not art for the gardeen... this is art of the garden harvest.. along with mountains of cookies , cakes and ices piled at my front door...
they have these,Marazpan treats.. they look like they were made of sculptyclays..
