Sieves are usually made from bronze or stainless steel wires. They are available in varying degrees of fineness and sizes are quoted according to the size of the opening or in wires per inch. An 40-60 mesh sieve is normally required to screen glazes to make sure they have no coarse particles that could disrupt the fired surface. In order for a porcelain to fire speck-free it would normally need to pass a 200 mesh ( about 75 micron opening) or finer screen.

| law of large numbers |
This law states that the larger the number of exposures considered, the more closely the losses reported will match the underlying probability of loss. The simplest example of this law is the flipping of a coin. The more times the coin is flipped, the closer it will come to actually reaching the underlying probability of 50% heads and 50% tails. See also Degree of Risk, Odds, and Probability.
