The spouts of functional pouring vessels have to do two things: deliver well and hopefully look pleasing. Stint in either task and ya got problems, some less bothersome than others. And after my last post about the snub-spouted Cube Teapot, it might be manifestly simpler to say that functional spouts really have only one thing to do: pour well, if not flawlessly.
So what, specifically, goes into a smooth-functioning spout, whether on a teapot, pitcher, ewer or creamer? Yes, style still counts, but for now we will just explore how precise forming affects better function.
