A Beehive Pot is a chimney pot consisting of a straight, round tube, which tapers suddenly but slightly towards the top and is terminated usually with a round lip. Beehive pots resemble the Ogee Pot, but have straight sides below the top taper, rather than tapering in towards the base. Research Beehive Pot
A chimney is a channel or flue by which smoke or fumes from a fire, furnace or engine ascends and escapes away from the occupants of the building. In this sense the first chimneys we hear of are no earlier than the middle ages. The longer a chimney is the more perfect is its draught, provided the fire is great enough to heat the column of air in it, because the tendency of the smoke to draw upwards is in proportion to the difference of weight between the heated air in a chimney and an equal column of external air. Smoky chimneys may be caused either by the presence of other buildings obstructing the wind and giving rise to irregular currents of air, or by improper construction of the fireplace and adjacent parts of the chimney. The first may generally be cured by fixing a chimney-pot of a particular construction, or a revolving cowl, on the chimney top, in order to prevent the wind blowing down; in the second case the narrowing of the chimney throat will generally create a better draught.
Britain has a rich history of chimneys ornamented with pots - the clay or stone tubes atop of the chimney structure, over five hundred different designs at one time being catalogued, such as the very common and plain ogee pot, and the ornamental Ryburn, knight and bishop pots. Towards the end of the 20th century, with the decline in coal fires, fireplaces and as a result chimneys started to decline in British buildings.
