Schweinfurt Blue





or Reboulleau's Blue, is prepared by fusing together equal weights of

ordinary arseniate of protoxide of copper and arseniate of potash, and

adding one-fifth its weight of nitre to the fused mass. The result is,

so to speak, a sort of blue Scheele's green, into which latter colour it

soon passes when rubbed with oil.
