2006 Watering Cones

In Guamuca, my Studio in Colombia I made many different containers for watering plants, fruit trees with porous pots. They work by capillarity! For garden use, I made large porous bowls, round buttom and placed them in a hole near the trunk of fruit trees. These release water slowly. Then, how to make something for planters? After trying several shapes, for small containers these watering cones work perfect. Now I continue making them just by adding 20 or 25% grog to stoneware clay, wedge it very well and fire the cones at low temperature to make it porous.
