Back arch : a concealed arch carrying the backing of a wall where the exterior facing is carried by lintel.
Baluster : a dense textured (aphanitic), igneous rock relatively high in iron and magnesia minerals and relatively low in silica, generally dark grey to black and feldspatic; a general term in contradistinction to felsite. A light-coloured feldspatic and highly siliceous rock of similar texture and origin.
Bed : the top or bottom of a joint, natural bed; surface or stone parallel to its stratification.
Bed : In granites and marbles, a layer or sheet of the rock mass that is horizontal, commonly curved and lenticular, as developed by fractures. Sometime applied also to the surface of parting between sheets.
Bed (1) : In stratified rocks the unit layer formed by sedimentation; of variable thickness, and commonly titled or distorted by subsequent deformation; generally develops a rock cleavage; parting, or jointing along the planes of stratification.
Belt course : a continuous horizontal course of flat stones placed in line marking a division in the wall plane.
Bevel : when the angle between two sides is greater or less than a right angle.
Bluestone : a dense, hard, fine-grained, commonly feldspatic sandstone or siltstone of medium to dark or bluish-grey colour that splits readily along original bedding planes to form thin slabs, Bluestone is not a technical geologic term. It is considered to be a variety of flagstones, the thin relatively smooth-surfaced slabs being suitable for use as flagging. The term has been applied particularly to sandstone of Devonian age that are being or have been quarried in eastern New York and Pennsylvania and in western New Jersey, but similar stones that occur elsewhere may be included. It has also been applied in places to thinly layered gneisses and schist that can be split and used as flagging, but such stones are not properly embraced by this definition although they may be marketed properly as flagstone.
Bond stone : used in varying percentages to anchor or bond the stone veneer to the backing material. Bond stones are generally cut to twice the bed thickness of the material being used.
Border stone : usually a flat stone used as an edging material. A border stone is generally used to retain the field of the terrace of platform.
Box : a tapered metal box wedged in the top of columns or other heavy stones for hoisting.
Broach : to drill or cut out material left between closely spaced drill holes; a mason’s sharp-pointed chisel for dressing stone; an inclined piece of masonry filling the triangular space between the base of an octagonal spire and the top of a square tower; a type of chisel used for working narrow surfaces.
Brownstone : sandstone of characteristic brown or reddish-brown colour that is due to a prominent amount of iron oxide, as interstitial material.
Brushed finish : Obtained by brushing the stone with a coarse rotary-type wire brush.
Building stone, natural : rock material in its natural state of composition and aggregation as it exists in the quarry and is usable in construction as dimension building stone.
Bull nose : convex rounding of a stone member, such as a stair tread.
