Stone is an earthen, mountain born material that has become highly prized in the manufacture of a wide variety of coasters. However what is not commonly known is that there are a number of different kinds of natural stone, and each one has its own peculiar properties and features which sets it apart from the others. In this article we will explore some of the different types of materials that are used in coasters, and what the benefits and drawbacks are of each different type.

Sandstone beverage coasters are probably the most popular because they have the unique property of being absorbent. They have tiny pores in the surface of the stone, which allows condensation from a sweaty glass to sink into the material, waiting to be evaporated away into the air. The absorbent quality of this stone is a benefit, but it is also a drawback, making the coaster more likely to stain or discolor over time.

Slate coasters have a similar absorbent quality, but it is not as dramatic as in sandstone. Slate is also often multi colored, meaning that its surface has a wide variety of contrasting patterns and hues, which can hide stains, making these pieces slightly less functional, but dramatically more durable.

Marble coasters are a relatively classic accessory, which are commonly seen in upscale homes and offices around the world. They have the shimmering elegance of some of the great works of art and architecture from history, and as such are often highly prized in this application.

However marble is a non absorbent material, and so, often these pieces have to be equipped with some sort of lid or lip that will hold the moisture from the glass on each piece. Further, the marble itself has to be protected from any acidic substance, as that can discolor the stone and ruin its look permanently.

There are a wide variety of stone coasters available, and each type of material has a completely different set of features and characteristics. It's important to understand these characteristics in order to care for the coasters, as well as understand the function of these pieces in your home.
