AND HOW TO USE THEM.
79
Take a piece of putty two inches in diameter, and put it in a piece of thin muslin, twisting up the latter so as to form a handle, and having one side smooth. Clean the glass well, fit in your stencil, and pat the surface over with the pad. Take the stencil carefully off, and when dry, varnish with transparent varnish.
To make this varnish, dissolve one part pearlash in about eight parts water, add one part shellac, and heat the whole to the boiling point. When the lac is dissolved, cool the solution, and saturate it with chlorine until the lac has all settled. When it is dissolved in alcohol, it forms a varnish which is as transparent as any copal varnish.
