Weathered reef-building coral material
First Claim
1. A process for manufacturing a weathered reef-building coral material, comprising the steps of;
- immersing weathered reef-building coral in an aqueous 0.1N to 6N alkali solution under reduced pressure to carry out alkali washing to make the aqueous alkali solution penetrate into the weathered reef-building coral throughout its fine structure inside the porous tissue; and
washing it with water until a washing from the inside of the porous tissue is neutralized, wherein said alkali washing is carried out by forcibly passing the aqueous alkali solution through the weathered reef-building coral immersed in the aqueous alkali solution or is carried out by agitating the weathered reef-building coral in said aqueous alkali solution and wherein the aqueous alkali solution is heated.

Abstract
Weathered reef-building coral is immersed in an aqueous alkali solution under reduced pressure to carry out alkali washing to make the aqueous alkali solution penetrate into the weathered reef-building coral throughout its fine structure inside the porous tissue, which is subsequently washed with water until a washing from the inside of the porous tissue is neutralized.
As a result of this washing, various marine algae, various microorganisms including Vibrio bacteria inhabiting the ocean and other various organic substances held in the inner fine structure of weathered reef-building coral can be removed. Thus, a weathered reef-building coral material can be obtained whose safety has been ensured. This weathered reef-building coral material is suitable for food materials, filter mediums for water purifiers and so forth.
