The dimensions of the elements (1) are derived on the one hand from the lateral dimensions a, b of the stoneware (4) and on the other hand from the thickness of the corner glazed earthenware (3), which gives for the thickness of the element (1) the total sum a:2 - d, or b: 2 - d. The doubling of the walls as well as the usual utilization of half stonewares (4) lead to a series of elements (1) having the following lengths: a:2 - d, a:2, a - d, a, 3a:2 - d, 3a:2, 2a - d, 2a, etc. This gives eventually a series of following element heights: b:2 - d, b:2, b - d, b, 3b:2 - d, 3b:2, 2b - d, 2b, etc. Other series of heights and lengths result from the two basic series, in which the smallest member is a member of a basic series. In a preferred embodiment, the stoneware (4) has a visible square face and the thickness a:4. All the elements have thus the same thickness and lengths, respectively heights, equal to a:4, a:2, 3a:4, a, 5a:4, 3a:2, 7a:4, 2a, etc. |
