The most absorbent drink coaster is one made of stone. There are many different types of sandstone coasters you can purchase for the purpose of providing a base on which your guests can rest their drinks to avoid the moisture from collecting on your furniture and marring the finish. Coasters made from absorbent stone have a cork or rubber protective bottom so that they won't scratch your furniture and keep the drink from sliding off.



A drink coaster made from Indian sandstone contains an explosion of colors that will complement any room decor. The trail of colors shows the stone in a smooth texture. Experience the colors of shifting sands or a complex pattern of hues that present a stunning visual effect. Other options in this material for drink coasters (http://www.thirstycoasters.com/servlet/-strse-Name-Drops/Categories) include ruby red coasters that give the impression of desert sand. You can also choose neutral colors that will not overpower your decor but blend in naturally with the wood on which they are placed.

A marble drink coaster is very elegant. The colors are reminiscent of ancient times, since this stone itself has existed since before history. These coasters are hand crafted and polished and if you look closely you may be able to see traces of fossils in the surface. There is a wide range of options for you to choose from in this variety from having coasters with images of clouds in the stone to those that are fiery red or midnight black.

Natural slate is also a popular material used in the manufacture of drink coasters. Since slate forms in layers in the environment, each drink coaster may have slightly different colors. This is due to the collection of chemicals present at each stage of the formation of the slate. Each layer seems to blend into the other creating seamless lines of color that present a very elegant surface. Two of the most popular coasters in this stone are those made from African slate and Indian slate.

A drink coaster made from limestone is also very absorbent. You can see the weathering of the rock in the colors of the stone coaster (http://www.thirstycoasters.com/servlet/-strse-Garden-Accents/Categories). A golden color will make you think of bright sunny days in the depths of winter while one that is blue-gray in color will help you recall images of the ocean and soft summer breezes.

Some forms of stone are more porous than others and thus will hold more of the liquid that condenses on the outside of the glass. Most of the manufacturers do coat the surface with varnish to add a protective coating on the stone, but this does not detract from its absorbent quality. Some of them are really expensive when made from imported stone and can become collector's items. A drink coaster made from Chinese slate, for example, seems to look like a map of the earth with darker brown sections that look like the continents.

One thing that you have to be careful about when you buy a stone drink coaster set is that you cannot put these coasters in the dishwasher. Although they do need to be cleaned for them to retain their absorbent and porous qualities, you only need to wipe them off with a damp cloth. If you do need to give them a more rigorous cleaning to remove stains, make sure you do not use a harsh detergent and let them dry in the air.
