All marble is porous by nature.
All natural store is porous and needs to be sealed. Travertine is the most porous over marble and granite
Sedimentary rocks such as sandstone are examples of porous materials.
Than?? Marble certainly isn't porous.
Sorry but i only got 1 porous rock and 1 non-porous rock :)Porous rock = sandstonenon-porous rock =granite
yes its a porous surface and will absorb liquid and stain
Marble countertops are durable as long as they are taken care of. Marble is porous so it will scratch easier than a granite countertop. It is also important to use a sealer on your marble countertop. Be careful not to clean marble with abrasives and caustic cleaners because damage will occur.
porous brick is a new produce which is economical on energy and has a sensible structure it has many excellent properties such as resisting to thermal ,resisting to erode ,resisting to corrosion, the most it owns a longevity
As marble is porous, any moisture in the air or liquid water can penetrate it, therefore a drop in temperature below 4 degrees Celsius will result in any water within the marble expanding, and the marble will be cracked and damaged.
Travertine is an earlier form of marble. It takes thousands of years for travertine to turn into marble. Being said that they are almost the same, we should distinguish them in the ways they are different:-Travertine is porous, marble is dense, which makes travertine an ideal product for outdoors such as pool decks and patios and marble ideal for indoors.Here are some samples of travertine pavers and marble tiles:http://travertinemart.com/Pavers.php
Honed marble is a more natural looking marble without the polished, mirror like finish. It is more porous than polished marble and is therefore not recommended for use in areas where staining may occur. Sealant companies may claim to be able to seal honed marble, but from what we have been able to discover, sealants only work for a temporary period.
Bacteria also can easily penetrate the porous surface of marble. Marble is also easily stained / corroded by acidic foods and drinks leaving the surface rough leading to more cleaning problems. For these reasons stainless steel is the recommended surface for commercial kitchens.
