Abstract: Non-porous thermofoil decorative objects and a method for thermoforming such objects are disclosed herein. A preferred embodiment of the decorative object comprises a non-porous substrate and a thermofoil thermoformed to the substrate. The substrate of this embodiment has a top surface, a flat bottom surface, and an exhaust port extending from the top surface to and bottom surface. The thermofoil of this embodiment is thermoformed onto the top surface and the edges of the substrate and covers the exhaust port from the top. An exemplary exhaust port can be located at any location of the substrate, but if the top surface of the embodiment additionally has a steeply raised level, the exhaust port is preferably located at an edge of the raised level. A preferred diameter of the exhaust port is 1/32?-5/32? and most preferably 3/32?.
