Stone: To care for your stone sculpture, make sure it is free of scratches by sanding it with waterproof sandpaper, 400 grit or finer. The finer the sandpaper used, the smoother and shinier the sculpture will appear. Then, warm it in the oven at 250 degrees Fahrenheit (121 degrees Celsius). You can also warm up a sculpture by sitting it out in direct sunlight for a few hours. Once warmed, polish the sculpture with a paste wax (such as Johnson’s). The wax should melt as it is absorbed into the stone. Let the piece cool and the wax dry to a matte finish. Buff with a soft cloth.
Wood: Any unsealed wood can be periodically rubbed with boiled linseed oil available at most hardware stores. This will help prevent cracking and splitting.
