About RABCO, Inc. Color Glazes and Sized Color Specks

RABCO, Inc. has been supplying sized color specks for use in ceramic coatings since 1979. Our customer list includes virtually all domestic manufacturers of glazed wall and floor tile, commercial dinnerware and cookware, prepared hobby glazes, lamp bases and artware, structural clay products, specialty porcelain and sanitaryware. In addition to the conventional “gold dust” and “salt & pepper” effects, sized color specks can be used in many other ways to provide your products with new and different looks.

Our regular sized color specks offer another design tool to enhance the "flat" look of many ceramic coatings. These materials can introduce complimentary or contrasting colors to the background color. Indeed, our "Stainspex" colors can actually tint the glaze and provide the visual interest of increasingly larger specks of the same color in the tinted background.

Our transparent specks added to flat matte or engobe coatings will pick up and enhance or magnify the color of the base coat providing a pleasing contrast of shiny spots of the same color as the non-reflective background.

Combining several colors and sizes can result in the ever-popular "Granite" look. Using only one color in a disco-applied granite glaze can shift the overall color effect without another glaze application.

RABCO specks can also be used to add the third dimension of height or depth to your coating in a controlled manner. Ask us about "pebbles" or "dents". And, combining a soft glaze -- in sized color speck form -- with a harder glaze coating can produce interesting effects, especially on vertical surfaces.

RABCO specks can simulate iron spots on brick and quarry tile surfaces and can be used to produce the ever popular "enamel ware" coatings on whiteware bodies. Also, we offer "reactive" specks, the use of which can produce unusual and often unpredictable results in certain glaze compositions.

We also manufacture a complete line of premixed, completely prepared dry glazes for a wide range of firing conditions and product application. And, we offer our experience in developing glaze coatings for your exclusive use under certain conditions.

Perhaps you have other thoughts on how RABCO color specks and/or glazes can be used on your products. If so, do not hesitate to call on us. We would be pleased to discuss our materials with your and supply you with technical assistance and samples of any of the above-mentioned products for evaluation in your plant.
