When it comes to adding images to memorials, a consideration that needs to be taken is whether to have them done by sandblasting or laser etching. There are pros and cons of each technique, usually dependent on the type of image you need and the material the headstone is made from.
Sandblasting is a more modern process used for lettering granite memorials and can be used for adding images to memorials that require being coloured or gilded. A stencil is cut on a rubber tape this can be hand drawn and cut out by hand or used on a computer with a machine similar to a printer using a sharp blade to cut out the desired design. The rubber tape is then lined up and affixed to the memorial. The areas that have been cut are then removed, using compressed air and sandblast grit. With a lot of skill the design is then sandblasted onto the memorial. For lettering and for a coloured design the sandblasting must all be taken to the same depth to give a quality finish.
It is possible to do a shaded sandblast design. The initial process is similar but the attention to detail during the sandblasting process is very skilled as it is done in layers. This means only a highly skilled craftsmen can offer this service. Sandblasting is best carried out in workshop conditions in a concealed unit and using dust apparatus in a dry environment. The process can be done in the cemetery for additional lettering or for adding designs but only on a dry day and the area must be enclosed so no harm can be caused to surrounding memorials or to passers by.
Some masons will sandblast marble, slate and stone but at Sarsfield we we do not, as it is not the traditional method for adding designs or lettering to these materials. Traditionally these materials are hand cut and hand carved, so at Sarsfields we do like to try and keep to traditional practices as and when we can.
Laser etching is a process for adding designs to granite memorials. This involves a specialist machine which through a computer and a very fine diamond point can remove the polished surface and the process will place a design on the stone. The design cannot be gilded, but it can be highlighted so the design is more visible. Alternatively a highly skilled artistic mason can colour it so that if you run your finger across the design it has no depth to it and, you can barely feel it. This process must be carried out in a clean workshop environment as any dust can effect the process and damage the design or the diamond point.
We at Sarsfields can offer advice regarding ornamentation as to which process is most suitable for your particular choice of memorial. We are able to produce a wide range of bespoke sandblasted and laser etched designs to help personalise your memorial.
