I like to drink tea from fairly large mugs. A few years back, I found
a number of Royal Doulton everyday mugs on sale for a few dollars each.
The mugs are very lite weight, and they hold a fair bit of tea. These
are the plain cylindrical variety.
(you know, volume = pi r^2 h)

A little later on, I discovered the ones that change from smaller to
larger as you move up the cup (more of a cut off cone shape). I like
these ones so much now, that the cylindrical ones seem boring.

In any case, I think tea cups should be very lite weight, made of good
china and with a nice pattern.

As far as tea pots go.. In the cheapest range, it seems that China is
turning them out for about $4 each. They're sturdy and great for
everyday use. They are a bit heavy tough.

If you're willing to spend $10-12, there's a fair number of lite weight
good quality China ones.

I've seen really really nice ones for about $20.

Of course, you can always spend $200 on a Royal Doulton or other brand
name pot.
