Coldcasting tutorial

(Keep in mind that you need a lot less resin than usual due to the powder taking up a lot of space)

In this tutorial I will go through "coldcasting" - in other words casting with real metal powders.The general idea behind coldcasting is to add a fairly large ammount of metal powder into the resin - after the resin has cured it will keep some of the properties of the respective metal like weight shine and feel. Some usual metals that are used for coldcasting is aluminium, copper, brass and bronze.So to start things of - these are the materials that will be used for this tutorial. (AKA just the powder, a mold, mixing cup and resin). The powder I'll use in this tutorial is copper.Start of by mixing the resin togetherHere comes the tricky part of this tutorial - how much powder you should use. The general ammount should be somewhere between 30-50%, this differs between each material though. There's a lot of trial and error to this, if you use too much you may risk the finished cap/ stem being too brittle. A thumb rule that I personally use is to pour in powder until the pile that builds up surfaces the resin. This is just for the cups that I use, so you have to try this out yourself to master the technique.Mix mix mixJust pour it in and close the mold - now wait.Here's what the cap looks like right after demolding. Now to polishing!After wet-sanding for a couple of minutes, here's what the finished cap looks like!
