Natural Stone Definitions
E
Eased Edge
A slightly raised, chamfered, or radiused edge to eliminate the sharpness of the fabricated stone edge.
Eaves
The underside of a sloping roof that overhangs a wall.
Edge Chiseling Tool
A tool with carbide jaws used to create a “pitched,” “quarry,” or “chiseled” edge without using a hammer and chisel.
Edge Profile
The specific contour to which an exposed edge has been shaped, normally for decorative purposes.
Edge Profile
The specific contour to which an exposed edge has been shaped, normally for decorative purposes.
Efflorescence
A salt deposit, in the form of a white powder residue that forms on the surface of stone, brick, or mortar. It is caused by alkalis leached from the masonry or soil and carried to the surface by moisture.
Elevation
A drawing of the vertical faces and elements of a structure, either interior or exterior.
Encrinal Marble
Marble deriving decoration from fossils (encrinites) or shells.
Engineered Stone
A man-made product composed of a blend of natural minerals (generally quartz) and man-made agents (such as polyester, glass, epoxy, and other such ingredients).
Entablature
A composite beam member carried by columns and made up of an architrave (bottom), frieze (middle), and cornice (top).
Entasis
The slight convexity designed in a column shaft for aesthetic purposes. This is done intentionally to offset the perceived illusion of the concavity of a perfectly straight shafted column.
Epoxy Resin
A flexible, usually exothermic curing resin made by the polymerization of an epoxide, used as an adhesive.
Erection
The process of setting vertical dimensional stone into place.
Etched
A decorative surface pattern created by a variety of methods, produced either by chemical or mechanical methods.
Exfoliation
Peeling or scaling of stone surfaces caused by chemical or physical weathering.
Expansion Anchor or Bolt
A socket that grips a drilled hole in concrete by expanding as a tapered bolt is drawn into it.
Expansion/Contraction Joint
A flexible joint between stone units designed to expand or contract to accommodate movements due to temperature change or dynamic structural movement.
Exposed Face
The visible side of any stone element.
