About Porcellanite
Name:
Etymol: Italian porcellana, porcelain.
A group of siliceous-rocks that have the texture, lustre and conchoidal fracture of porcelain. A dense siliceous rock having the texture, dull luster, hardness, conchoidal fracture, and general appearance of unglazed porcelain; it is less tough, dense, and vitreous than chert.
The term has been used for:
1. an impure chert, in part argillaceous;
2. an indurated or baked clay or shale often found in the roof or floor of a burned-out coal seam, see porcellanite (metamorphic).
3. a fine-grained, acidic Tuff cemented by secondary silica.
and
4. A silicified radiolarite
The first definition is most generally used.
Also spelled: porcelanite; porcelainite.
See Also: siliceous shale, Porcelain Jasper, haelleflinta, clinker
The names "porcelain-jasper", "porzellanjaspis", and "basaltjaspis" are inadequate.
