Almost any stone can be used for drink
coaster. They protect the furniture and are easier to maintain since
they can be wipe cleaned and do not spoil due to moisture. Rather
sandstone coasters are considered absorbing coasters.
The marble or soapstone coasters may be carved or inlayed, granite
and slate are often finely polished or for a rustic look, smoothed but
not polished to shine. Their beauty lies in the combined effect of
natural stone character and human imagination and artistry. They have
soft base or rubber feet to protect the furniture from scratches.
