You can, however, add a small amount of sand or silt during the beginning of your grinding stages if you have no used slurry. This can help speed up the grinding action until the rocks create their own slurry. How can I safely dispose of used grit (or slurry)? Grit and therefore slurry are nontoxic.

Cryogenic grinding is a very effective technique for taking hard substances, like plant and animal tissues, and turning them into dust. The tough carbohydrates of plant tissues become very fragile at -196°C and easily shatter. The two concerns with cryogenic grinding is that the sample may warm up, and secondly, throughput is very low.

"If you add sand to that paste it becomes mortar. And if you add to the mortar large aggregates — stones of a diameter of up to an inch — it becomes concrete." What makes concrete so strong is the chemical reaction that occurs when cement and water mix — a process known as hydration.

Why? The physical chopping breaks the plant's cell fibrous walls (made of tough cellulose) and allows the cytoplasm to leak out. 2) Place the chopped onion into the mortar and thoroughly grind it with the pestle. Why? Grinding continues the physical breakdown of the tough cell walls. 3) Add about 10 ml of detergent solution and grind again.

Typically, edging is done during the centering process. Figure 7 shows a centering and edging machine that can grind the outer diameter and put bevels on both sides in one run. Although less common, bevels can also be added after centration, either using a stone grinding wheel or convex or concave bevel tools.
