Bookmatched and Butterflied

When a block of stone is sliced to produce individual slabs, the granite and marble quarries will usually implement a practice of bookmatching the slabs, also known as “butterflying”.  

Above, a rough block of Calcatta marble is ready to be sliced into slabs.

To bookmatch slabs, every other slab receives a high polish on opposite sides of the rock. When consecutive slabs are placed side by side, they are nearly mirror images of one another. Thus, they are like a book that has been opened, or, like a butterfly with identical wings spread out.

Here the Calcatta slab slices have been polished in bookmatch fashion.

Bookmatching is useful detail for fabricators when they would like the seam in a kitchen countertop to flow continuously. When the slab has a good deal of movement, especially, or when the color variation is great, granite fabricators can simply continue the countertop stretch into the next consecutive slab.

Countertops that employ bookmatched slabs are usually able to have a stripe or wave continue across the seam, for a complete visual of the geological process that formed the stone underground over millions of years.

A beautiful example of how movement can be continued across a seam.
