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.

石材经过酸洗，残留的酸性物质，与水分反应，也会造成锈黄。在安装的时候，一些铁质的配件生锈，进而扩散石材表面，也会造成表面锈黄。因为造成石雕出现锈斑的原因是因为本身含有铁矿物，或是外来的铁锈，因水分渗透，从而产生锈斑。

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.

若想避免出现锈斑，降低石材的含水量是一种有效的手段。降低石材含水量的常见方法有在安装前，做好防护，防止水分入侵，避免配件生锈。在清洗的时候，避免使用含酸性的清洗剂。在安装的时候，谨慎选择配件。石雕讲究造型逼真，手法圆润细腻，纹式流畅洒脱。
