Abstract: A block and peg combination for a modular wall construction is disclosed including a cast block of cementations material having a front face, a rear face, two sides with each side extending between an edge of the front face and an edge of the rear face, a bottom, and a top parallel to the bottom. The front face, rear face and two sides are substantially normal to the bottom and top. The front face has a width between the two sides which exceeds the width of the rear face between the two sides whereby the block tapers at the sides from a wide dimension at the front face to a narrower dimension at the rear face for forming curved walls. The bottom defines at least four spaced-apart holes adjacent the respective sides of the block. At least two pegs, each peg having a conical head portion and a shaft portion, are utilized for insertion into the spaced-apart holes on the bottom of the block.

Abstract: Brick is normally extruded and sized in length, typically by extrusion through a die having the section of the brick followed by cutting the extruded section into the length desired for the brick. Before the brick is dried and fired, but after extrusion and cutting to length, the brick is randomly deformed, preferably by tumbling, to impart to its respective surfaces random appearance. Glazes and sand can be added during the tumbling process. After having its surfaces randomly deformed, the brick is partially straightened, preferably to impart to the length and width of the brick a uniform overall nominal dimension. There results, after drying and firing of the product, a brick having overall dimensionality but with a surface patina characteristic of so-called antique brick.
