The sink is then mounted to the bottom of the material from below. Especially for under-mount sinks, silicone-based sealants are typically used to assure a waterproof joint between the sink and the countertop material. The advantage of an "under-mount" sink is that it gives a contemporary look to the kitchen but the disadvantages are extra cost ...
Knapping is the shaping of flint, chert, obsidian, or other conchoidal fracturing stone through the process of lithic reduction to manufacture stone tools, strikers for flintlock firearms, or to produce flat-faced stones for building or facing walls, and flushwork decoration.
Engineered stone is typically worked in the same way as natural stone using a water jet cutter or a diamond blade. This is in contrast with solid surface materials which can be cut with regular saws. [6] The material can be produced in either 12 mm, 20 mm or 30 mm thicknesses.
Stone has been used for carving since ancient times for many reasons. Most types of stone are easier to find than metal ores, which have to be mined and smelted. Stone can be dug from the surface and carved with hand tools. Stone is more durable than wood, and carvings in stone last much longer than wooden artifacts.
Precut stone is a DFMA construction method that uses large machine-cut stone blocks with precisely defined dimensions to rapidly assemble buildings in which stone is used as a major or the primary load-bearing material. Massive precut stone construction was originally developed by Fernand Pouillon in the postwar period. He referred to the ...
A stone being split using a single plug and feathers. Multiple sets of plug and feathers are typically used to split a single, large piece of stone. The stone is first examined to determine the direction of the grain and to identify any potential defects. After the location of the intended split is chosen, a line is scored on the surface of the ...
A dutchman, or in some uses graving piece, is a matching piece of good material used to replace a relatively small damaged area that has been cut out of a larger item, to avoid having to replace the entire item; or, any of various techniques for accomplishing such a repair. In some cases, the meaning has been extended to include small pieces ...
Cutting-stock problems can be classified in several ways. [1] One way is the dimensionality of the cutting: the above example illustrates a one-dimensional (1D) problem; other industrial applications of 1D occur when cutting pipes, cables, and steel bars. Two-dimensional (2D) problems are encountered in furniture, clothing and glass production.
