How to Throw a Stoneware Aquarium
Robert began making his Stoneware Aquariums in the early 1970s. The following images and text explain his techniques for making these unique pieces.
Using an Oversized Bat
Robert made his own "over sized" bats to go on to his Shimpo potter's wheel. In this image he is lowering the bat on to the pinned wheel head.
Wedged Clay put on to Wheel head
110 pounds of soft plastic clay is dropped on the wheel, as close to center as possible.
Using Body Weight
Using his body weight, Robert works the clay out to the desired diameter and leaves the suggestion of a well.
Opening The Form
Soft clay makes it possible to center and open the form. The Shimpo wheel can stall under the weight, if too much pressure is applied.
Raising The Walls
Bringing the form out is the most stressful part, using his right arm as a pivot point on his right leg, helps when strength is not sufficient.
Walls Are Up
Throwing the piece is not as difficult as trimming the “galley”, where the glass sits. In order to trim the form it must be flipped over on to its rim, while still leather hard.
Making The Front Rim
The front viewing port on the aquarium (the top) is turned back on itself to create a flat receiver, where the glass will be attached.
Adding Surface Texture
Once the neck is added to the body, legs are attached and the whole form is textured. The exterior of these pieces are left unglazed, however, a line glaze is applied to insure a water tight finish.
15 Gallon Standing Aquarium
Aquariums are thrown on the wheel with using between 30 to 110 pounds of clay. A thick wall is necessary for long strength and durability. Robert has been making Fountains and Aquariums since 1973.
