This section de-scribes common finishes and classifies them into a numberof families by relief or roughness. The finish
48、es in each fam-ily are also arranged from the least relief to the most relief.Stone finishes are a complex matter for a number of rea-sons. New manufacturing or finishing methods or variationsor combinations of other methods of finishing stone are con-tinually being developed. Stone finish names som
49、etimesoverlap or are variations of other finishes.Finish options for any kind of stone vary by the geologiccategory of the stone (whether igneous, metamorphic, orsedimentary) and the unique combination of geological orphysical properties of the stone type. This means that anyparticular finish cannot be put on every type of stone (seeApplicability of Finishes for Various Stone Types Table inGuide C1528 for Selection of Dimension Stone for ExteriorUse). The individual definitions are sometimes nonspecific
