Granite is prefer to used and not marble, because it’s thin we need a plain black color. Also granite is more rigid material to avoid the break the 2cm piece through cutting process. Personally I prefer black shadow line to be thinner than 2cm but then it will become weaker. There are three types of black granite, beside artificial stone read How to Select Black Granite article for more information. Artificial stone is not suitable because it will efflorescence and appear with with grey and white spots. The craftsmen need to cut the granite using saw cutting machine at marble factory, and then to glue it with the riser according to floor and riser height.

Usually marble’s face is polished or treated, but edges need to be polished at site. Some types of marble will polished at site and appear as it face. Other types like Crema Nova, Omani marble, black marble and granite or any high strength marble won’t give good results. Polishing high strength marble requires to polish using different grades sanding papers to get to smoother surface.

45 degrees Marble Edges Connection

45 degrees edges connection fit marbles that have veins, it gives the continuity of surfaces  appearing as a marble block. This connection doesn’t need to polish edges as in traditional connection. Implement this connection by trimming both edges at 45 degree then to install them together. The connection will be very thin, and require to fill either by tiles grout or marble adhesive. When edge cut at a 45 degree thin as pencil, soft marble will cut perfectly, but high strength marble will fragment. Alignment is another problem face this connection, where if angle is less than 90 degrees craftsman can’t install it. Therefore craftsman like to make narrower than 45 degrees to align easier, however it will fragment easier during edge cutting. Also 45 degrees connection used for ceramic and some types of porcelain, when tiles body is different than tiles face.
