When Jeeves serves tea to Bertie it is usually from a silver tea pot and fine bone China. When Jeeves has his own tea in the kitchen it is brewed in a brown betty teapot and poured into plain white tea cups as seen in the foreground of the screen capture here.
The teapot used on the Jeeves and Wooster set appears to be a Price Bros. teapot similar to the one below.
In this screen capture from Jeeves and Wooster we see an interesting glass bowl on the coffee table on the set of the Bertie Wooster flat. This glass bowl is seen on the table throughout the series. Recently I decided to search for one on eBay and found one very like it
