Glossary of Terms

Glossary is usually defined as an alphabetical list of technical terms in some specialized field of knowledge. This knowledge base glossary provides a collection of knowledge base documents that define many technical terms. These terms are arranged alphabetically, but you can quickly jump to a specific term by selecting its first letter from the index of the knowledge base glossary below.

EFFLORESCENCE
A deposit or encrustation of soluble salts generally white, usually carbonates or sulfates, that may form on the surface of stone, brick, concrete or mortar when moisture moves through and evaporates from the masonry
EGGSHELL FINISH
Dull polish or matt surface
EIGHT-CUT FINISH
Fine, bush-hammered; interrupted parallel markings not over 3/32 in. apart; a corrugated finish; smoother near arris lines and on small surfaces
EMULSION
Mixture of solid particles of binder and the liquid carrier in which they are suspended but insoluble
ENCRINAL MARBLE
Marble deriving decoration from fossils or shells
ENDOLITHIC
The process of adding color to incised lettering in stone
ENGINEERED STONE
A manmade product composed of a blend of natural minerals and manmade agents (such as polyester, glass, epoxy, and other such ingredients). This product can give the appearance of a “stone like” surface, but it does not possess the characteristics of a natural stone. It’s range of use is limited
ENTABLATURE
A horizontal, projecting group of stones immediately above a column capital. Consists of three major parts: architrave, cornice, and frieze
ENTASIS
The curve resulting from the gradual diminishing in the diameter of the upper two-thirds of a column
EPOXY
A class of synthetic, thermosetting resins which produce tough, hard, chemical resistant coating and excellent adhesives
EPOXY RESIN
A flexible, usually thermal setting resin made by polymerization of an epoxide and used as an adhesive. They are characterized by toughness, good adhesion, corrosion, chemical resistance, and good dielectric properties. Most epoxy resins are the two-part type, which harden when blended. It is used as surface coatings, adhesives for composites and for metals, floor surfacing and wall panels, cements and mortars
ERECTION
The process of and setting vertical dimensional stone in place
ETCHING
Occurs when stone is eaten (or neutralized) by an acid. It often looks like and is mistaken for a watermark.
EXFOLIATION
Peeling, swelling or scaling of stone or mineral surfaces in thin layers, caused by chemical or physical weather or by heat
EXPANSION
Enlargement of length and bulk by reason of temperature rise or absorption of water
EXPOSED AGGREGATE
Phrase applied to the larger pieces of stone aggregate purposefully exposed for their color and texture in a cast slab. Can be done by casting on a slab or by application to an existing wall over epoxy or cement coat
