Started work on my next gold bar replica project. I made a mold of an original gold bar prop I have from the movie and made some resin duplicates, as well as some wax ones for later. My first attempt at a legit metal version I'm attempting with sandcasting off of the resin positive. The result is not quite there, and wire-wheeling off the surface textures can lead to removing some of the crisper detail I was able to get in the top's designs. The lower portions defects are most likely caused by either impurities in the aluminum, or issues of initial splashdown when pouring. I can remove that by creating a void for the initial pour to hit that then steps down into the bar's negative. Next I'll try my hand at lost wax casting using plaster investment, and if that fails will move on to ceramic slurry/shell.
Eventually once I get a solid method developed, I'll get these polished up and gold plated. Also messing around with different metals. Having one weigh close to what a gold version would actually be gives the prop a wonderful feeling of heft and authenticity, and makes for a superb doorstop.
