Tea, coffee and chocolate became popular in Britain in the first half the 1700's.
Coffee and chocolate pots are taller than teapots to keep the spout above the sediment. Chocolate pots have have a hinged or detachable cap in the lid for a stirring rod. The earliest coffee and chocolate pots, before about 1730, were tapered cylinders with the handle at the side, rather than opposite the spout. Later in the 1700's, they were made in a more curved "baluster" shape. Around the turn of the 1800's, vase shaped pots were made but most manufacturers soon reverted to the baluster shape.
