longer than a softer sedimentary or metamorphic rock. I mostly make thin sections of basalt, which is the dark gray type of lava. It is finegrained with little or no quartz, so basalt grinds down quickly and evenly. To finish, cement a cover slip onto the rock, being careful to once again make the cement free of bubbles with the warming plate.

In this methods paper, the thin section blanks were described as chips which were to be circular.
