Abstract

An epoxy rock coaster is provided that absorbs and contains the condensation from drinking glasses, bottles and cans and excess water from plant pots. The epoxy coaster includes a composition of different sized stone aggregates mixed with an epoxy resin system. The composition is added to an open top plastic vessel having a flat bottom and upwardly extending side wall, completely filling the vessel wherein the composition surface is tooled to a flat exterior finish and cured. The composition solidifies, bonding to the interior bottom and side of the vessel forming a porous structure therein which creates voids and pockets within the structure providing openings to contain condensation and excess water from the drinking containers and plant pots.
