I made this Egyptianesqe vase in the summer of 2016. Although the walls are pierced, it can be used with or without flowers and holds up to 17cm of water. 

LxWxH:
13x13x23 cm
 
Grey stoneware made from a blend of clays, fired to 1220° C
Watertight, dishwasher and oven safe, though best to wash by hand if possible
