TURNER’S CEMENT.
Sometimes the workman is too much hurried to wait till the work can be glued upon the chuck; the following cement will be found useful. Take two pounds of Burgundy pitch, one pound of rosin, one pound of colophonium, two ounces of yellow wax, and one ball of whiting. Melt all, except the latter, in an earthen pot, over a slow fire. When it begins to bubble, stir it well with a stick to prevent its passing the edge of the pot, and when all is quite melted take it off the fire. Add the whiting, finely powdered, little by little, stirring in well till the contents are perfectly mixed. Replace the pot on the fire, still stirring it; and after a few minutes, pour all the cement quickly into a tub or basin of cold water for about a minute. Then take it out, and knead it well with the hands. Roll it into sticks upon a smooth stone, and plunge them into cold water to harden. The strength and goodness of this cement depends greatly upon its being made as rapidly as possible. To use it, melt the end of one of the sticks by putting it near the fire; rub it on the chuck; when you think there is sufficient cement laid upon it, heat the bit of wood or ivory you wish to unite to it, and the warmth will make it adhere firmly.
Another cement, that is preferable for using in cold weather, is made by adding two pounds of Burgundy pitch, two ounces of yellow wax, and two pounds of Spanish white. These are melted together, rolled into sticks, and used as above; one stroke of the mallet will detach the work from the chuck when joined with this cement.
