Building Bricks
| Materials Required: | About 3 pounds of clay, |
| 2 level boards, 15 by 20 inches, | |
| ½ yard of white cheesecloth, | |
| A rolling pin, | |
| A foot rule, | |
| A strong, sharp knife. |
The clay of which these bricks are made should be well kneaded, and it should also have a great deal of what potters call "grog" mixed through it. "Grog" is baked clay pounded into small pieces—an old flower pot will do if you are using flower-pot clay. Mixed with the unbaked clay it tempers it, that is, it makes it less likely to shrink and crack in baking.
Cover a level board with a piece of wet white cheesecloth and tack it securely upon it. Mould the lump of clay into a square, by hand, lay it on the board and pound it with the thick part of your hand into an irregular square cake, then roll it with a rolling pin till it is about three-eighths of an inch thick. Have ready another board the same size and covered with wet cheesecloth, lay it on top of the clay sheet and reverse it so that the clay shall be transferred to this second board. Roll it again till quite smooth and set it away overnight. The next day take a foot rule and a sharp pencil and mark the clay sheet into bricks, two inches long by an inch wide. Cut them out with a strong, sharp knife, but do not lift them until they are thoroughly dry, which will be in three or four days. They should then be carefully packed and sent to the pottery to be fired.
