Dog Sculpture Continues
Mantrid - Thursday, March 25, 2010 - 5:26pmbronze | ceramic shell | foundry | lost wax casting
Further progress on the dog sculpture. Its been raining here all week AGAIN. However, today I was off work and the rain stopped, so I got myself set up to do the casting this morning. Below are pics of the results, but first some pics of the shell application.
First layer of slurry and stucco. The green/yellow colour is a pigment in the binder that changes to orange when the coat has dried
About the 4th layer I think.
Final layer of slurry to secure the particles of the last stucco layer stop them dropping off and leaving bits everywhere
Another wax I did at the same time
Same wax with some ceramic shell applied. This image clearly shows how the exposed surfaces dry much faster than the nooks. The orange indicates its dry enough for the next stage, yellow = still damp.
I actually did three shells in total this run here are the two others besides the dog
Two done one to go. At this stage I had to wait for another batch of bronze to melt.
The aftermath. The little piece of rod on the left is my steel stirrer that melted and fell off. I had the furnace burning much longer this run as I was cleaning up alot of crudy left over bronze and also I needed to refill the crucible to do the three shells, so I think I was getting to iron melting temps.
All stood up. It started raining again just as I finished taking this shot. Prefect timing. The quality of the castings is good on the female figures, which is to be expected as I have done these ones enough. The dog was better than expected for a first go. Some work to do on it which I will show when I get it sandblasted. I was pleased to see that most of the fine vents filled so I have some nice compatible welding wire to.
