What is the spout of a teapot called?
Spout – The shaped funnel through which the tea is poured and directed. The majority of antique teapots have an integrated strainer, located at the junction of the body and spout. Shoulders – These may be embellished for decorative purposes.
Why do teapot spouts drip?
This scientific jargon boils down to the fact that tea tends to stick to the inside of the spout as it is poured. The flow of tea then begins to stop-start, causing a dribble effect.
Why does my teapot leak?
Dr. Keller showed that it was air pressure, not surface tension – that causes drips. “It is simply that at the pouring lip the pressure in the liquid is lower than the pressure in the surrounding air,” he said, “so air pressure pushes the tea against the lip and against the outside of the spout.”

Do teapots need lids?
A teapot is a pretty sad sight without a lid, whether lost, stolen or smashed. The lid is not as structurally essential as the handle, meaning it’s less likely to re-break while you’re pouring and leave you with a hot mess literally.
Why do teapots have a hole in the lid?
The hole in the lid of some teapots is a vent hole. By allowing stream to vent it prevents both a build up of pressure in the pot and rattling and clanging as steam otherwise escapes around the lip of the lid.
How do you cut a spout for a teapot?
When the teapot body is ready, the spout will be cut with a single long stroke and joined to the body. That will be next. Just a note about the mandrel and it’s use…. most potters actually pull a hollow spout over the mandrel by twisting a cone of solid clay onto the form and pulling a hollow spout down the tapered tool.
How do you make a wheel thrown spout?
When a wheel-thrown spout is made, the wall section naturally tapers from the bottom to the top. To replicate this thinning of the spout wall, I use a dowel to roll a small taper into the entire spout, thinning the top 1/3 of the spout just a bit. After this secondary thinning, I again trim the spout blank with the template.
What should be the thickness of a wheel thrown spout?
The clay should be just a tiny bit over 1/8″ thick. When a wheel-thrown spout is made, the wall section naturally tapers from the bottom to the top. To replicate this thinning of the spout wall, I use a dowel to roll a small taper into the entire spout, thinning the top 1/3 of the spout just a bit.
