StonePly: Stone Glossary
G
- Gang saw
- A machine also known as a "frame saw," used to cut stone blocks into slabs of predetermined thickness.
- Gauged or gauging
- A grinding process to generate stone slabs or stone panels of the same thickness.
- Glass backing
- In translucent StonePly the glass backing is the layer bonded to onyx, alabaster and certain translucent marbles to allow light to pass through them.
- Glass seam
- Stone vein fillings of coarsely crystalline calcite, which do not necessarily decrease the strength of the stone structure.
- Grain
-
- The primary direction of the mineral composition and arrangement in stone; it is also the easiest direction of cleavage.
- A very small particle of rock, crystals and sand grain in a stone.
- Granite
-
A coarse-grained, hard igneous rock, gray to pink in color, composed of feldspar, quartz, and lesser amounts of dark ferromagnesium materials. Gneiss and black "granites" are similar to true granites in structure and texture, but are composed of different minerals. Commercial and scientific definitions of the granite group are explained in detail in ASTM C119. See granites section of the website.
- Greenstone
- A metamorphosed or altered basic igneous rock, typically with poorly defined granularity, ranging in color from medium-green or yellowish-green to black. Commercially and per ASTM C119 greenstone may be guide specification. A recommended specification for the finishing and installation of stone. See specifications.
- Guillotine cut
- Cutting a stone panel or slab, generally slate, by the guillotine method to produce a jagged, irregular and chipped edge.
H
- Hand or machine pitch faced (rock faced) ashlar
- A rustic appearance for veneer stone created by chiseling the stone face with a hammer.
- Head
- The visible surface of the jointed end of any given piece of stone with a gauged dimension not more than the minimum thickness of the material specified. Also known as "return head."
- Honed finish
- A stone panel finish characterized by a very fine, satin-smooth surface appearance with little or no gloss. http://stoneply.com/finish_options
- Honeycomb
- An aluminum honeycomb reinforcing panel that provides strength and rigidity to the natural stone face panel of StonePly panels.
- Honey Onyx
- A light yellow, honey colored onyx marble.
I
- Igneous
- Any of the various volcanic rocks or rocks crystallized from molten magma, solidified after the molten state, such as granite.
- ILI (Indiana Limestone Institute)
- A trade organization founded for the dissemination of information on limestone standards, recommended practices, grades, colors, finishes, and all technical data required for specifying, detailing, fabricating, and erecting Indiana Limestone. Publishers of the Indiana Limestone Handbook and other technical publications.
- Impregnation
- Administration of a chemical containing stain inhibitors that penetrate below the surface of the stone.
- Incise
- To carve stone or slash inwardly or engrave, as in an inscription.
