This cement can be used in any situation and for any purpose to which any other mortar or hydraulic cement can be applied. It does not become perfectly hard within one or two months.

The sand should be neither coarse nor fine but of a middling quality or about the size of the common pop(p)y seed. If the sand is too coarse the mortar will be short or brittle . . . If the sand is too fine the cement will shrink and crack after it has been used.
