eagle beaka 6″x3/4″ outside corner trim shape. (ac 106) earthenware. a glazed or unglazed nonvitreous ceramic whiteware. 
  
eased edgewhen referring to a slab material, the square edge profile normally has softened edges as opposed to sharp square edges for added safety.
  
eavesthe underside of a sloping roof that overhangs a wall.
  
edgebonded tilesee definition for pregrouted tile.
  
edge-mounted tilea type of mounted tile wherein tile is assembled into units or sheets and are bonded to each other at the edges or corners of the back of the tiles by an elastomeric or resinous material which becomes an integral part of the tile installation. units or sheets must meet criteria of back-mounted sheets. see definition for mounted tile.
  
efflorescencethe residue deposited on the surface of a material by the crystallization of soluble salts. a finishing tool used on the edges of fresh concrete to provide a rounded corner.
  
eggshellingthe texture of a fired glaze similar in apperance to the surface of an eggshell.  electrical porcelain. vitrified whiteware having an electrical insulating function.  electrolysis. production of chemical changes by the passage of current through an electrolyte.
  
elevationa drawing of the vertical faces and elements of a structure, either interior or exterior.
  
embosseda decoration in relief or excised on the ware surface. 
  
embossmenta decoration in relief or excised on the ware. 
  
engineered stonea manmade product composed of a blend of matual mimenrals and manmade agents ( such as polyester, glass, epoxy, and other such ingredients). this product can give the appearence of a “stonelike” surface, but it does not possess the characteristics of a natural sotne. its range of use is limited.
  
engobea slip coating applied to a ceramic body for imparting color, opacity or other characteristics, and subsequently covered with a glaze. 
  
entablaturein classical architecture, the upper part of an order, comprising architrave, frieze, and cornice.
  
entasisthe curve of the upper two-thirds of a column.
  
entrained airmicroscopic air bubbles intentionally incorporated into mortar or concrete during mixing, usually by use of a surface-active agent, typically between 10 and 1,000 n.m in diameter and spherical or nearly so. (see also air entrainment.)
  
epoxy adhesivea two-part adhesive system employing epoxy resin and epoxy hardener used for bonding of ceramic tile to back-up materials.
  
epoxy grouta two-part grout system consisting of epoxy resin and epoxy hardener, especially formulated to have impervious qualities, stain, and chemical resistance, used to fill joints between tile units.
  
epoxy mortara two-part mortar system consisting of epoxy resin and epoxy hardener used to bond tile to back-up material where chemical resistance of high bond strength is a consideration.
  
epoxy resinan epoxy composition used as a chemicalresistant setting adhesive or chemical-resistant grout.

erectionthe process of setting vertical dimension stone into place.
  
etcheda decorative surface pattern created by a variety of methods, most often with abrasive chemicals or sandblasting.
  
eutectic, deformationthe composition within a system of two or more components which, on heating under specific conditions, develops sufficient liquid to cause deformation at minimum temperature.  eutectic equilibrium (eutectic). the composition within any system of two or more crystalline phases which melts completely at minimum temperature, or temperature at which such a composition melts. 
  
expansion bolta socket that grips a drilled hole in stone by expanding as the bolt is screwed into it.
  
expansion jointa joint through tile, mortar, and reinforcing wire down to the substrate.
  
expansion-contraction jointa joint in a wall designed to allow the expansion and contraction of the wall due to temperature change. an expansion joint compresses as panels expand, a contraction joint expands as panels contract. exposed aggregate – phrase applied to the larger pieces of stone aggregate purposefully exposed for their color and texture in a cast slab.
  
exposed facethe visible side of any stone element.
  
exposed-aggregate finisha decorative finish for concrete work achieved by removing, generally before the concrete has fully hardened, the outer skin of mortar and exposing the coarse aggregate.
  
extra duty tilesee special purpose tile.
  
extruded tilea tile or trim unit that is formed when plastic clay mixtures are forced through a pug mill opening (die) of suitable configuration, resulting in a continuous ribbon of formed clay. a wire cutter or similar cut-off device is then used to cut the ribbon into appropriate lengths and widths of tile.  face-mounted tile. see under tile, mounted.
