The ultimate Zen garden accessory is the stone urn. Filled only with water and a few fallen leaves, it defines tranquility. Unfortunately, these stone beauties cost hundreds of dollars.

Luckily, a concrete mix called “hypertufa” was developed that has the look of stone, specifically the volcanic rock called tufa. In England, farmers carved watering troughs from this soft, porous rock. Eventually, these tufa troughs became too expensive, and hypertufa containers replaced them. The materials used to make our container are inexpensive, and the process is delightfully messy. When it comes right down to it, a hypertufa casting is just a fancy mud pie.
