	Grinding slab - Encyclopedia, History, Geography and Biography
		In archaeology, a grinding slab is a ground stone artifact generally used to grind plant materials into usable size, though some were used to shape other ground stone artifacts.
		Grinding slabs used for plant processing typically acted as a coarse surface against which plant materials were ground using a portable hand stone, or mano ("hand" in Spanish.
		Portable grinding slabs are referred to as metates or querns.

	Ophthalmic Hyperguide. Section: Clinical Optics
		Slab grinding is a method of adding prismatic effect in the reading area of a lens without producing prism in the distance vision area.
		Slab off, or base up slab, grinding is achieved by changing the center of curvature of the grinding tool that is cutting the front lens surface, without changing the curvature that is being cut.
		The slab on grinding, or base down slab, is the reverse of the slab off method, in which a base down wedge is added to (or left on) the inferior area of the lens, adding base down prism.

		Grinding should be performed across the entire lane surface to achieve the highest degree of ride quality, uniform skid resistance, and uniform appearance.
		Survival analysis conducted to quantify the effectiveness of diamond grinding in extending the service life of concrete pavement showed that the probability that diamond-ground pavements will have to be overlaid or reconstructed before the pavement reaches 30 years of age is less than 15 percent.
		Grinding shall be performed in a longitudinal direction and shall begin and end at lines normal to the pavement centerline in any ground section.

	Ground stone - Wikipedia, the free encyclopedia
		In archaeology, ground stone is a category of stone tool formed by the grinding of a coarse-grained tool stone, either purposefully or incidentally.
		Some ground stone tools are incidental, caused by use with other tools: manos, for example, are hand stones used in conjunction with metates and other grinding slabs (querns), and develop their ground surfaces through wear.
		Other ground stone tools include adzes, celts, and axes, which are manufactured using a labor-intensive, time-consuming method of repeated grinding against a harder stone or with sand, often using water as a lubricant.

		Two-hand manos were very common, but they were used with slab metates, rather than with trough metates.
		As the name suggests, slab metates have a flat or nearly flat grinding surface.
		Slab metates were often used inside stone bins built specifically to hold the metate at the proper angle for grinding; these bins are called “metate bins” or, sometimes, “mealing bins.” Metate bins are found in a variety of locations, including in rooms that apparently were used exclusively for the purpose of grinding corn (Figure 2).

		Grinding tools found in a variety of Neolithic contexts in Sweden strengthen ritual interpretations of grinding tools, for example as burial or sacrificial offerings, or as votive offerings in wetlands.
		Grinding tools may therefore be interpreted as an active part of the Neolithic social and ritual life.
		A symbolic order associating grinding and grinding tools with death, transformation and transition, as well as engendered human relationships, identity, and social and economic reproduction, may well have been present in the Neolithic.

		In the case of the grinding feature F27 (Unit 1423), someone made a final use of a sandstone abrading slab (for ochre processing) and then carefully turned the slab over onto its face.
		That is, the abrading slabs are very small and shallow, implying use with a one-hand mano or small abrader (the only complete handstones and hand-held abraders found are all petite, usable with one hand).
		These observations imply the multiple purposes of the grinding slab fragments used as handstones and the abrading slabs found with them.
