Description: |
| Abstract:
The process is as follows: Take of common anthracite coal unburnt such quantity as will best suit the kind of clay to be made into bricks or tile and mix the same, when well pulverized with the clay, before the same is molded. That clay which requires most burning will require the greatest proportion of coal dust. The exact proportion cannot therefore be specified but in general three fourths of a bushel of coal dust to one thousand brick will be correct. Some clay may require one eighth more and some not exceeding a half bushel. The benefits resulting from this composition are the saving of fuel and the more general diffusion of heat through the kiln by which the whole contents are more equally burnt, the process of burning is also accelerated by the coal dust. If the heat is raised too high the brick will swell and be injured in their form.
Claim:
The using of fine anthracite coal or coal dust with clay for the purpose of making bricks and tile. |
