It is very likely that they are using a glaze that melts a little
hotter than the base glaze; they melt it, then grind it up, like with
a frit. That way, you get tiny chunks of a white, glaze-y material.
Because it melts a little hotter than the base, it doesn't get hot
enough to fully melt into the surrounding glaze.
