If you are using a ball mill in your operation resist the temptation to think that using one is just a matter of throwing in some pebbles, pouring in the glaze, and turning it on for an hour or so. As a general rule you should mill for the same amount of time, fill the jar to the same level, use the same charge of pebbles and the range of sizes
