# How is it possible to increase mercury's specific weight?

Is it possible to change mercury's specific weight to make it heavier? By mixing it with anything? But not by changing its temperature.

• Mix it with osmium. – ParaH2 Oct 7 '16 at 21:48
• Gold might be a cheaper option. – Ivan Neretin Oct 7 '16 at 21:52
• Is the mixture a liquid at room temperature? And if you could please tell me about the mixing process ? Ive heard that there's a way to "cheat"it and make it heavier. – user23592 Oct 7 '16 at 21:58
• @IvanNeretin not necessarily. At current market prices, gold is more expensive than any other precious metal. – Gimelist Oct 8 '16 at 2:48
• Use $\ce{^{203}Hg}$ instead. It's 0.5% heavier. – Zhe Nov 7 '16 at 14:54
