Nicolas Boyes Stone Conservation Ltd. is one of the few private companies in the UK to own and operate fully licensed conservation lasers, used for the sensitive and selective removal of soiling and corrosion products. Laser cleaning can be carried out on site as well as in our workshops. NBSC currently works in conjunction with Lynton Lasers Ltd, manufacturers of the Phoenix Conservation Laser.
The level of cleaning that can be achieved using the laser is determined by the settings used and the operator's skill. In the majority of cases the intention is not to remove all soiling, but to remove just the darkest areas of soiling leaving behind the patina. The images above show the laser in use at Rosslyn Chapel and a close-up of an area of detail where the left-hand side is untouched and the right-hand side has been cleaned using the laser.
If you havent seen a conservation laser in action before then take a look at this short video showing Martin Cooper of the National Conservation Centre using a Lynton Lasers Phoenix Conservation Laser to clean a plaster mould:
