Tumbler and Split process
Both treatment are applied when piece is dry, Post-packing. Result is a piece seeming a natural stone.
Split process is cutting piece in half obtaining two pieces with one finishing face. This could be two sides if it is requested.
Tumbler process is turning and hitting between pieces obtaining a finishing more natural (older aspect) because it is all faces.
If pieces were produced with Color-Mix, the result will be closer to natural stone.
