COLOROBBIA MOTHER OF PEARL LUSTRE - 25 GRAMS

Mother of Pearl Luster is an overglaze that produces beautiful opalescent colors. It is typically applied to accent or highlight ceramic wares or jewelry. Lusters are consideed overglazes because they are typically applied to glaze-fired pottery, on top of the glaze. The piece is then fired again at a low temperature (see details below).

Mother of Pearl luster appears iridescent when applied on top of a white glaze. Luster colors will vary depending on the glaze underneath them. As always, we recommend conducting tests prior to use on your work.

What is a Luster?
Lusters are overglazes. This means they are applied to a surface that has been glaze fired. Lusters take on the texture of the underlying surface that they are applied to (matte, satin, or glossy). Lusters are made with complex combinations of metallic salts, resins and oils. These formulations are designed to effortlessly create amazing metallic and iridescent effects.

Tools
-Use soft bristle round or flat brushes.
-Use disposable paper towels

Handling and safety
Lusters are safe to handle when used with the correct personal protective equipment (PPE). Lusters are flammable and must be keep away from any heated elements or open flames. Always work in a well ventilated area and wear a NIOSH approved respirator. Avoid contact with skin by wearing fitted vinyl gloves. If you happen to get any luster on your clothes or skin, wash with soap and warm water immediately. During firing, avoid breathing fumes and/or kiln exhaust.

Application
Wear appropriate PPE and work in a ventilated area. Your ware and work area should be clean, dry and dust free. If you choose to use rubbing alcohol to clean your ware before application, allow extra drying time as alcohol contains water. To paint, use a small brush that will fit easily inside the diameter of the luster bottle. Dip the point of the soft bristle brush into the luster. The brush bristles should have a “wet” appearance. Lightly swipe any excess luster on the bottle rim. Do not thin luster solution as it can cause streaking and diminish metallic or iridescent effects. We recommend that you experiment with your studio setup before any large scale work is done. Make sure to completely dry your work in a clean area, free from dust, dirt, and moisture.

Clean up and storage
Make sure to wipe the threads on the glass container before capping tightly. Put the glass luster bottle inside the clear plastic container to contain any lingering fumes. To prolong your Lusters, store in a cool/dry place. Hot and humid environments can cause this product to thicken. 

Firing
Fire the fully dried lusters ware to cone 019-018. This should be a fast fire with the peep-holes open. Good firing ventilation is essential for this product.
