mold

Working on a shell

Shell mold

I’ve promised myself to try to focus more on projects of my own, in between contract work for other people. I find it so easy to fritter time away when I’m not meeting other’s deadlines. So I’ve started back working on a big shell project I first started over 3 years ago. Back then I got as far as sculpting the shell out of clay, and making a ridiculously big and heavy plaster mold of it.  It’s about a metre long. Luckily I did have the sense then to make a cradle on casters for it, so I don’t break my back trying to maneuver is around.

A few days ago I sealed the plaster with layers of shellac, which turned it this beautiful golden mustard colour.

Now I am paper mache-ing it inside with tissue paper. I want it to look flimsy and papery and almost transparent, but I don’t know how few layers I can get away with, and still have it come out of the mold intact. The idea of using very fine fibreglass is tempting, but I am sworn off working with fibreglass.

There are a few more photos at Flickr, where I’m making a photoset.

Giant cross-section flower

Cross-section flower

My third project for Floriade was making a giant model flower in cross-section, to be the central display in CSIRO’s Division of Plant Industry’s information tent. I really enjoyed making this, too. Some projects go really easily and this was one of those!

The petals were the main challenge, but I decided pretty quickly to use a molded felt technique that I had previously tried with some masks. Essentially you saturate felt in white PVA glue, mold it to the shape you want, and then let it dry. It adopts the shape and becomes fairly hard and plasticised in a way. You can paint it, too, and the way the paint bleeds through the felt can be used in different ways, some quite sensuous. In this case, I made a petal shape in clay and each petal had a double layer with some aluminium flat bar running up the middle to give it extra rigidity. The interesting thing about the technique apart from the obvious texture, is that the felt can be stretched and pulled but remain in one piece. In this respect natural wool felt is much better to work with because it pulls and moves much more than synthetic felt. But synthetic is okay if you don’t have a choice.

I think the flower may end up being displayed in the CSIRO Discovery Centre, where some of my insect models are too; I hope so.
