This set of four (4) coasters measure 4" in diameter and approximately .25" thick. This set tends to be more refined than our more rustic, natural gray set which is approximately .4" to .5" thick. All coasters are backed with a cork bottom for added tabletop protection. All of our items are one of a kind. I cast each unit in a hand made mold for about a week. I then hand burnish each, and then apply two coats of carnauba wax. We believe that all of our coasters offer the benefit of being both absorbent and relatively stain resistant since the sealer that we use yields just the right porosity to our coasters. It is noteworthy to mention that the white color is the most stain resistant to the condensation/water stains that can occur with cold drinks. Please note that although they are sealed to resist staining, they will certainly develop character/patina over the years. This item is not composed of typical concrete. It has taken me years to perfect this mix design. All of our concrete items are composed of an advanced cementitious mix which utilizes extremely small particulate, very little water, and reactive recycled pozzolans...The result is an incredibly strong, smooth, and tactile surface that is more similar in physical characteristics to ceramic or aluminum than it is to concrete! Please note: While our concrete mix design yields an aesthetically predictable product, our concrete can display slight variation in color and in texture. This creation will only get better with age, developing rich character and patina as it ages. Because cement cures at an asymptotic rate, all of our concrete products actually get MORE durable as the years go by!
