Second, is there any particular glaze which is best to cover cured polymer clay with? I've tried Sculpey®, but for some reason it sometimes forms little bubbles on the surface of the clay when dried. Thank you very much.
Kato Polyclay clear medium liquid can be used like a glaze. It is best to apply this product, and any glazing material with a good-quality paintbrush to help avoid creating bubbles and brush strokes. Kato Polyclay clear medium liquid is cured by baking, following the manufacturer's instructions. Mona Lisa™ Metal Leaf™ top coat sealant offers a shiny, smooth finish on polymer clay. It is cured by air drying. Signature Series Magic Glos™ Top Coat by Lisa Pavelka will add a shiny finish and also a dimensional effect. This product needs to be cured with a true UV light source, such as the sun or Lisa Pavela's UV Light.
Over time, wear and tear you may find the finish for each of these diminishes or flakes off; they can be reapplied, if necessary.
Sanding, polishing and buffing the surface of polymer clay will yield a shiny finish that will last a long time as well as one that will be enhanced over time with wear. Sanding and polishing the surface using all grits of sand paper followed by polishing papers will yield a smooth and shiny surface. For an even greater shine, buff the surface with a muslin wheel fitted to a Foredom® Bench Lathe or the flex shaft of a rotary drill.
