When it comes to purchasing or collecting rosewood furniture—whether antique or modern—it's often challenging to rely on scientific testing methods like a professional lumberjack. In most cases, people don’t have the tools or knowledge to take pieces apart and send them for lab analysis. Instead, traditional experience and visual inspection remain the primary ways to distinguish genuine from fake. New Rosewood Furniture 1. Rosewood is known for its rich texture and natural color, which stand out immediately. It is typically finished with traditional, clear wax that preserves its unique, natural beauty. The surface of the wood appears noble in shades of deep purple or black, with minimal visible grain patterns. Occasionally, you might spot fine golden lines or delicate curly patterns under magnification. With a 60–100x magnifying glass, you may even see small pores filled with golden dust, creating a sparkling effect that resembles a starry sky. 2. Some manufacturers mix rosewood with old redwood (such as from Laos, Cambodia, Vietnam, or Thailand). This can be hard to detect without experience. Old redwood usually has more noticeable dark stripes and visible patterns, but lacks the golden star-like effects found in real rosewood. 3. If the wood is coated with wax or lacquer that alters its color, or if it’s deliberately aged to look old, it’s likely not genuine. These techniques are often used to deceive buyers. Antique Rosewood Furniture After being stored and used for over a century, rosewood furniture tends to show two common conditions: 1. If placed in areas with limited sunlight, such as near doors or windows, the true color and texture of the wood can be clearly seen, making identification easier. 2. However, if the furniture has been exposed to sunlight for too long, the surface may turn pale or grayish, making it harder to tell what type of wood it is. Despite this, the smoothness of the surface and the feel of the grain are difficult to imitate with other types of wood. Once cleaned and polished with wax, the elegance and sophistication of authentic rosewood become evident. Some people believe that new rosewood fades when soaked in water, while old rosewood doesn't. Others claim that new rosewood can’t be dyed, but old red sandalwood can. However, in reality, any leguminous wood will produce fluorescence when exposed to water or alcohol. For example, red sandalwood inlaid with jade is often mistaken for something mystical. But the truth is that rosewood dissolves easily in alcohol, producing a bright red color. When flooded with water, it releases a blue oily liquid. This phenomenon was commonly observed in imported woods during the Han to Qing dynasties, where the sap was used for dyeing fabrics or coloring furniture. This isn't a secret, nor is it a reliable way to determine the age or authenticity of rosewood. Only the heartwood of rosewood is suitable for making high-quality furniture. The tree must grow for around 500 to 1,000 years before it's ready for use. While some people classify rosewood as "new" or "old" based on color, this distinction is largely commercial and not scientifically valid.

Aluminum curtain wall is a kind of building decoration material widely used in modern architecture. Aluminum curtain wall is made of aluminum alloy, usually composed of panel, reinforcement and corner code. It has the advantages of corrosion resistance, excellent processing performance, strong decoration, environmental protection and energy saving. Aluminum curtain wall is divided into flat curtain wall, punched curtain wall, carved plate curtain wall. Installation methods are divided into frame type curtain wall, unit type curtain wall. Application areas are divided into commercial buildings, public buildings and residential buildings. In short, aluminum curtain wall, as a high-performance, high-quality building exterior wall decoration material, plays an important role in modern architecture. With the continuous progress of science and technology and people's pursuit of building quality, aluminum curtain wall will continue to develop and improve, bringing more innovation and development opportunities for the construction industry.
