You can mix the gold into the resin or make gold swirls. Another way to incorporate gold into the epoxy is to mix it right into the cups, pour a layer and then when that is still setting, pour another layer right beside it and use a blow dryer to slightly mix the two. You won’t believe the effects this gets! It’s so pretty. The possibilities are endless here.

You can also test old resin by mixing a small batch together and see if it cures. According to west system epoxy 3 years for resin and 2 years for hardener. DIY EPOXY RESIN PROJECTS FOR BEGINNERS:A rough estimate can be made based on the area and volume of the project’s surface. This calculation is based on the depth of your project. If the surface is flat length times width (L x W) can give you an estimated area. For depth simply multiply height of the project to get the estimated volume (L x W x H).

Much work has been undertaken to develop alternatives to cyanide leaching. 43,53–55 Thiocyanate has been found to leach gold as [Au(SCN) 2] − or [Au(SCN) 4] − in the presence of an Fe( II)/Fe( III) catalyst. It can act as a lixiviant over a wide pH range and is reported to be partly recyclable, but its use is restricted to higher temperatures. 55,56 Similarly, thiosulphate leaching ( eqn (2)) has been exploited in gold leaching and, although relatively cheap and less toxic than cyanide, it is also less efficient and significant problems exist due to complex reaction kinetics; even with the addition of oxidisers such as H 2O 2, the level of gold recovery by thiosulfate can be lower than 15%. 12,57,58 M.
