‘Rocky’ Horror Show! (Take 2)
I began work recently developing the idea of using concrete to create a representational structure of social divisions. The first attempt using lego as a mold (which can be seen here), proved successful, and after rethinking the kind of structure I wanted to create, I set my goal on achieving an inverted pyramid. The inspiration came from the Louvre Museum in Paris, which I have visited several times in the past, and always been fascinated by it.
When I visualised an opposing structure using concrete and natural wool, I was incredibly excited by the idea. I felt the interim show would be the perfect opportunity to showcase this work in progress. I didn’t quite expect the trials and tribulations of its creation though….
I began by making a smaller prototype, using a silicone mold and inverted base, which I purchased online. When I began, I noticed the silicone insert was slightly lopsided, which may have occurred whilst I was tapping out the air bubbles. With some degree of reluctance, I emptied it, washed it out and started again. The second attempt at this stage proved successful and whilst this was setting, I began considering how I could extend the lines and edges of the pyramid to create a larger structure.
I decided to create a template which could be inserted into the base of the mold using a thick 280gsm cardboard, which I then supported further with double walled cardboard I found in the recycling bins outside.
I used the silicone insert to extend the lines, used a craft knife to cut the shapes and pieced them together with tape.
First mistake!
Realised I’d folded it inwards, but I didn’t want the imprint of tape on the final sculpture, so had to turn it outwards…
The concrete was then mixed and slowly poured into the mold, which I had strengthened with the cardboard. I kept an eye on it - there were no leaks, but quickly I began to notice the cardboard warping as it was soaking the concrete mix…seems so obvious now!
Mistake #2
The cardboard was completely the wrong inner material for the mold, causing it to warp and affect the structural integrity of the concrete!
Takeaway.
I feel a bit stupid, as it was pretty inevitable that the cardboard would soak up the concrete and cause it to go out of shape. When the mold was removed, the part that extended beyond the silicone had deformed and crumbled. I’m going to use this piece to experiment with polishing the surface of the concrete however, ready for the ‘successful’ attempt.
My next attempt it to use perspex following the same method of cutting a template. Here we go again….
