Grind away the roughest edges with a small rotary tool after the stone is clean. If your quartz has large pieces you want to remove, cut off them off by sawing through them with a cutting wheel. Place the edge of the wheel against the part you want to cut away, then apply gentle pressure to grind through it.

Quartz Oddities. If it's more than 30µ thick, quartz will display 1 st order yellows instead of 1 st order grays. This is pretty common; sometimes it's better to let the quartz be a little thick than to risk grinding too much material off your thin section. Yellowish quartz is an acceptable sacrifice, because you can still infer that it ...

The plastic stage is a fun stage to be in. This is where the clay hits the wheel or the slab roller. At this stage, your clay is malleable (flexible), and you are able to create something on the wheel or hand build. When the clay is at this stage, the shapes you can mold your clay into are endless. After this stage, the molding is over.
