Aqua Regia solution is very energetic and potentially explosive. It is also very likely to become hot - more than 100°C. Handle with care. • Aqua Regia will melt some plastics and corrode most metals. • Never put Aqua Regia in a closed vessel; evolved gases will cause a pressure build-up and possible over-pressurization of your container.
