Important: Safety Warning
This page contains a formula or preparation using substances now known to be dangerously toxic, such as arsenic, mercury, lead, or cyanide compounds. Exposure to these substances can cause severe poisoning, permanent injury, or death.
In addition, this page describes trade processes that use dangerously toxic materials such as cyanide solutions, mercury amalgams, or strong acids. These processes require training, equipment, and precautions far beyond what the text describes.

Another (Melt together oz of antimony)
Melt together 4 oz. of antimony, 1 oz. arsenic, and 2 lbs. tin. This compound is ready for use. The first of these Spanish alloys would be a beautiful metal, if arsenic were added.
Engestroom Tutania.
Melt together 4 parts copper, 8 parts regulus of antimony, and 1 part bismuth.
When added to 100 parts of tin, this compound will be ready for use.
Kustitien's Metal for Tinning.
To 1 lb. of malleable iron, at a white heat, add 5 oz. regulus of antimony, and 24 lbs. of the purest Molucca tin.
This alloy polishes without the blue tint, and is free from lead or arsenic.
Solder for Steel Joints.
Take of fine silver, 19 dwts.; copper, 1 dwt.; and brass, 2 dwts. Melt these under a coat of charcoal-dust.
This solder possesses several advantages over Melt together 4 parts of copper, 1 of Bristol old the usual spelter solder, or brass, when employed brass and 14 oz. of tin to every lb. of copper.
For Common Jewellery.
Melt together 3 parts of copper, 1 of Bristol old brass and 4 oz. of tin to every lb. of copper.
If this alloy is for fine polishing, the tin may be omitted, and a mixture of lead and antimony substituted. Paler polishing metal is made by reducing the copper to two or to one part. Yellow Dipping-metal.
Melt together 2 parts of brass, 1 part of copper, with a little old brass, and oz. of tin to every lb. of copper. This alloy is almost of the color, etc., of gold coin.
Another. Good dipping-metal may be made of 1 lb. of copper to 5 oz. of spelter; the copper should be tough cake, and not tile.
When antimony is used instead of tin, it should be in smaller quantity, or the metal will be brittle. Imitation of Silver.
When copper is melted with tin, about oz. of tin to 1 lb. of copper, will make a pale bell-metal; it will roll and ring very near to sterling silver.
Tutania or Britannia Metal.
Melt together 4 oz. of plate-brass and 4 oz. tin.
When in fusion, add 4 oz. bismuth and 4 oz. regulus of antimony. This is the hardening, which is to be added at discretion to melted tin, until it has the requisite color and hardness.
