How to adjust the calligraphy gold powder

Gold powder is copper powder. I used this formula. I prepared a bowl, poured copper powder into it, and then mixed some gasoline. After stirring, I added a proper amount of alkyd varnish, and then stirred it evenly. The ratio of copper powder, gasoline and varnish is about 1: 15: 2, which is only an approximate ratio. When I mix it with it, it depends.
