Stone sculpture has a very mature production technology and a very, very long history, but sometimes rust spots can be found on the surface of stone sculpture. In fact, there are many reasons for the rust spots on stone sculptures. For example, when the raw stone is processed and cut with a steel sand sawing, the steel sand contaminated on the stone surface is not cleaned, and the rust spots can be formed after the action of water vapor. Generally speaking, the rust spots will not happen again after grinding and polishing.

石材經過酸洗，殘留的酸性物質，與水分反應，也會造成銹黃。在安裝的時候，一些鐵質的配件生銹，進而擴散石材表面，也會造成表面銹黃。因為造成石雕出現銹斑的原因是因為本身含有鐵礦物，或是外來的鐵銹，因水分滲透，從而產生銹斑。

After acid pickling, the residual acid will react with water and cause rust yellow. During installation, some iron accessories will rust and then spread to the stone surface, which will also cause the surface rust yellow. The reason for the rust spots on stone carvings is that they contain iron minerals or foreign rust, which produces rust spots due to water penetration.

若想避免出現銹斑，降低石材的含水量是一種有效的手段。降低石材含水量的常見方法有在安裝前，做好防護，防止水分入侵，避免配件生銹。在清洗的時候，避免使用含酸性的清洗劑。在安裝的時候，謹慎選擇配件。石雕講究造型逼真，手法圓潤細膩，紋式流暢灑脫。
