First, I want to revisit the two previous blog articles on this topic. The problem I’ve been working on is how to support a ceramic sculpture so it gets elevated off the pedestal surface. The first attempt included a spider mount, and the sculpture was velcroed to it. The second attempt used a concrete column that fit inside a cone-shaped supporting structure.
The problem with the concrete column (post) was that when I poured the column, I used a paper tube that was cut lengthwise, and a wire caliper held it to the desired diameter.
In this blog I will keep the ceramic cone as the support.
These are bisque-fired, white underglazed cones. The second cone has the overlap smoothed close tot he surface.
The improvement I introduce here is the technique that makes the pouring of the concrete column easier, and creates a better size fit with the ceramic cone.
I tried two separate ways to pour the concrete column.
Here I curved a plastic sheet into a tube.
Here I curved a sheet cut from a priority mailing envelope, and curved it into a tube. Both tubes are secured by white duct tape.
Both tubes were taped after they were curved into the respective cone support. This endures a snug fit after popuring the column.
The end of the tube was loosely surrounded by a thin plastic bag, the tube was filled concrete using a plastic spoon, and the plastic bag was allowed to settle onto the bottom of the sculpture. The entire contraption was standing on the bottom of the sculpture until the concrete set (about 1 hour).
Onto the bottom oft he “Ancient Manta I” sculpture I poured the column you see on the right.
On the right is the epoxy glue I use (this was left out of the second sculpture support blog).
On the left is support glued to the bottom of the “Ancient Manta I” sculpture.
While the pouring of the concrete was easier than before, I saw opportunities for further improvement.
- Columns work best when they are in the center of the sculpture. For the “Ancient Manta I” sculpture the support column is glued towards the back of the sculpture, and the front of the sculpture pulls the entire sculpture downward. The remedy for such situation is to form the upper part of the cone into a tube. The support column will be held in place and not allowed to tilt by the weight of the sculpture.
- The size of the ceramic cone is a little more overwhelming than I first saw. The thinning out of the ceramic cone will be a flat cone with a long (4-5 inches) ceramic tube.
