Foundry - Polygons in Bronze: Part 6
The good one
The giant ball of wax is what I carved from the inside to make the majority of the shell a consistent thickness. My hand still aches just thinking about this.
With my new mother mold completed, I was once again ready to pour wax... At least that was what I thought when I poured the wax into the mold. I balanced the mold on the grate of the pour station and it sat, cooling for a minute. Things were going well. Until the mold tipped over and poured molten wax. All. Over. I spent the next hour and a half of class scraping up the wax I spilled. Towards the end, it was somewhat relaxing... I did get one cast completed by the end of class, so that was good.
This cast turned out pretty good. Not perfect. Good enough. As you can see in the photos, there are some spots that are different colors, which is caused by adding wax to fill some holes in the surface. When carving the wax, I found that it was very difficult to work quickly without getting little bits of wax stuck in the recessed areas where I'd already carved. To keep this to a minimum, I started putting the wax in the fridge and only worked on it til it started to warm up. This increased the overall time to complete the carving, but also led to a better final outcome.
