SETTING.
After the brick have been enameled and are perfectly dry they are taken from the boards in the drying room, and after being placed on the flat-top spring barrows, care being ob served that the brick are so placed on the barrows as not to touch each other, they are then carried to the kiln to be set. In the burning of enamel brick it has been found advantageous to set green fire-brick 8 or 10 courses high over the bottom of the kiln, as well as to set the green fire brick for burning around the sides of the kiln to the same height as it is intended to set the enamel brick. In this way the first flash of the fires comes in contact with the ordinary fire brick, thus shielding the enamel brick. Care must be always taken in the setting of enamel brick to protect their enamel faces from the action of the flames as they pass through the kiln. The brick can be set on end, but the faces of the enamel brick must be closed in and protected from steam, smoke and sul phur during the firing process, and the brick should be set face to face, but never allowed to touch each other. The sides of the brick can be placed so as almost to touch, and as has also been previously stated, the brick which are enameled for white should face each other, and each color should face brick of the same color, thus preventing the chemical shading of the vari ous colors which would be likely to occur under the action of high temperatures.
Any practical man who has had experience in this line of work will find no difficulty with the setting of the brick.
A correspondent who recently wrote us from England says : "The way I would set the enamel brick in the kiln for burning is on the ' board,' which is a technical term in England for a peculiar manner in setting brick, and means to stand the brick on end and then place a row of brick on the top of them, edge up. By this means the face of the enamel brick is closed in and forms a nine-inch wall. This wall is carried up to a height of four feet, and between each wall there is left a space of about three inches, which allows the fire to work its way up between the wall or boards,' and prevents the smoke or sulphur from the coal from reaching the enamel face of the brick."
