A spider. See also:spider and slips
One in which clay, or other slip, is poured into plaster molds that absorb
the water, leaving a body the shape of the mold.
An easily fusible clay containing a high percentage of fluxing impurities,
used to produce a natural glaze on the surface of clayware.

a. That variety of foliation along which there has been visible
displacement, usually shown by bedding that is cut by the cleavage. Such
displacements are commonly shown along many adjacent cleavage planes.
Billings
b. Microscopic folding and fracture accompanied by slippage; quarrymen's
false cleavage.
c. S. Wales. The cleat of coal in planes parallel with slips or faults.
d. A type of cleavage that is superposed on slaty cleavage or schistosity,
and is characterized by finite spacing of cleavage planes between which
occur thin, tabular bodies of rock displaying a crenulated
cross-lamination. Syn:shear cleavage; strain cleavage;
strain-slip cleavage; close-joints cleavage. AGI
A friction clutch that protects a mechanism by slipping under excessive
load. Nichols, 1
A dike that has been intruded along a fault plane. AGI
The crystallographic direction in which the translation of slip takes
place. See also:glide direction
S. Staff. Sledge runners, upon which a skip is dragged from the working
breast to the tramway.
Veins of fibrous minerals, esp. asbestos, in which the fibers are more or
less parallel to slickensided vein walls. CF:cross fiber

A hold or grip on a drill rod, casing, or pipe by means of serrated-face
steel wedges or slips. Long
a. A contraction joint between two adjoining sections of wall, or at the
horizontal bearing of beams, concrete slabs, and precast units, to allow
slight movement in relation to one of the other. Hammond
b. A splined connection loose enough to allow its two parts to slide on
each other to change shaft length. Nichols, 1
Line that appears on the polished surface of a crystal or crystalline body
that has been stressed beyond the elastic limit. In quantity, they
represent the intersection of the surface by planes on which shear stress
has produced plastic slip or gliding. Syn:Lueders line

In blasting underground, a cut used in a wide tunnel face, in which each
successive vertical line of shots (round) breaks to the face made by the
previous round, so that the relieving cut moves across the end being
blasted. Also known as slabbing cut; swing cut. Pryor, 3
a. Closely spaced surfaces along which differential movement takes place
in rock. Analogous to surfaces between playing cards. Syn:glide plane;
gliding plane. Billings; AGI
b. The crystallographic plane in which slip occurs in a crystal.
