Slip — ceramics
A fine, liquid form of clay applied to the surface of a vessel prior to firing. Slip fills in pores and gives uniform color.  
 

Slumped Glass, Slumping — art glass, handblown glass
A warm glass technique where the glass is shaped by bending it over or into a mold. "Slumping," where a mold is used to cause already fused glass to take on the shape of a bowl, a plate, or similar object.

Terra Cotta — ceramics

Threading, Threaded — art glass, handblown glass
A thin line of glass wound around the body most often, the neck or rim less often (also see lip wrap). Created by touching to the piece the tip of a cone of molten glass on a punty and then turning the piece. Application is easier with threading rollers which are two sets of wheels on which the punty or pipe is placed. Because the wheels are set at an angle, each rotation moves the piece the same distance along the axis of rotation and the thread forms a spiral up the piece. If the piece has been formed in an optic before threading, the thread touches only on the ridges and during reheating forms spots of color. Threading may be done and then gathered over to put threads inside the glass. Also sometimes called trailing.
