Porphyry
Collection: Porphyry
The porphyritic rock currently used by the building construction industry for flooring, traditional and ventilated-wall facings, is a type of effusive volcanic rock-rhyolitic and rhyodalitic ignimbrites- that is commonly found in the earth’s mantle.
A particular chromatic effect, or a surface finishing, that the engineer intends to use to meet his project requirements, can be supplied by more than one material. However, when the designer requires a material with specific resistance and strength properties, the range of suitable materials can shrink considerably.
