Perform The Following Test Has It Been Doctored? Before purchasing a granite top perform the following test to find out if it has been doctored. Get a clean white cloth and apply some acetone (nail varnish remover) to the surface of the granite. If any residue or black color is observed on the top, do not accept it, it has been dyed. Take a piece of the "granite" you want to test and spill a few drops of lemon juice onto it. If you see that under the drops of lemon it develops very quickly dark spots, it means that it's a very absorbent stone and I would advise you against it. If it takes, say, a minute or so to be absorbed, then you're dealing with a level of absorbency that's easily controllable with the application of a good quality impregnating sealer. |

Always make sure you are receiving the same batch and have it itemised on your order. Also if the installer chips a corner or scratches the surface you will generally need a replacement piece. If the batch isn't available you may have a problem.
