An apparatus including a first device which moves a first portion of a soft, damp, slightly pressed slab out of alignment with a majority of the slab and thus introduces a first crack in the slab; and a device for spraying a first colored material into the first crack of the slab. The first device which moves the first portion of the slab out of alignment with the rest of the slab may include a first cylinder. The device for spraying the first colored material in the first crack of the slab may include a robotic apparatus. In at least one embodiment, the apparatus may also include a second device which moves a second portion of the slab out of alignment with the majority of the slab and thereby introduces a second crack in the slab.

This disclosure provides a rubber composite for use in a variety of applications, and methods for its preparation.

Various methods for making material capable of forming structural composites are disclosed. For example, a particular method may include growing an amount of cyanotic organisms, separating cell walls of the cyanotic organisms from internal portions of the cyanotic organisms to form a purified algae extract, the purified algae extract being from the internal portions of the cyanotic organisms, and applying an effective amount of alkaline water to the purified algae extract to form a balanced algae extract having little or no chemical reactivity, wherein a pH of the alkaline water is a function of a pH of the purified algae extract.
