I tend to be a little reluctant in using an acid on marble, especially HCL for several reasons:<div><br></div><div>1. The acid reaction is very difficult to control</div><div>2. If the proper dilution is not used it can erode away some of the softer veins leading to advanced deterioration</div>
<div>3. The acid reaction can look very spotty</div><div>4. Some grades of HCL can stain and discolor the stone</div><div>5. Fumes can be harmful to people as well as metal surfaces. I have seen metal tarnished by the fumes from HCL</div>
<div>6. Craftsman must have a high degree of experinece</div><div><br></div><div><br></div><div>If I were to use acid etching I would choose a milder acid such as sulfamic. The reaction would be slower and easier to control<br>
