What is Rouge primarily used for in dental laboratories?

Rouge is primarily used in dental laboratories for the polishing of gold and precious metals due to its fine abrasive properties. This material is typically composed of iron oxide and exhibits a fine texture that is effective in producing a smooth, high-gloss finish on metallic surfaces. When applied, it helps to enhance the aesthetic appeal of dental restorations made from precious metals, ensuring that they have a polished, reflective surface, which is particularly important for materials like gold that are often used in crowns and bridges.

The use of rouge is specifically suited to metals because it does not scratch or damage them, making it distinct from abrasives that may be more appropriate for other materials. Its application is often essential in achieving optimal results in dental work involving restorative materials that require a polished finish for both functional and aesthetic reasons.
