Stone cleaning


Conservation

In the conservation process, laser cleaning has been used with satisfying results in stone conservation to remove encrustation. Alongside to the aesthetically pleasing results, it is relevant to determine that laser cleaning does not have any adverse effects. Compared to the more traditional techniques, laser cleaning has many additional advantages: The diameter of the laser beam can be regulated so that areas of different dimensions can be treated. There is no physical contact between the object to be cleaned and the laser equipment. This aspect can be really relevant in treating fragile materials. Laser can be a selective tool: it can be regulated to remove dirt, without affecting the original material underneath. Lasers are effective in removing pollution encrustation from stone objects and have been used in conservation since the 1970's.
