The Composition not yet discovered. It makes a hard brittle metal not coinage & must be altered to make it malleable. The quantity of silver in it unknown. The Zink evaporates fast & by evaporating the colour will change, amp; therefore the composition is unfit for other uses. A mixture of silver & copper of more value.
