Hospitality Connect lists 46 Avanti teapots, spanning cast iron pots, glass pots, infuser teapots and a small number of related utensils. Black is the dominant finish, with hobnail and Camelia cast iron styles among the range.
Material is the decision that matters most. Cast iron holds heat longest, so it suits a table sitting where the pot stays out for a while, though it is heavier for staff to carry. Glass shows the leaf and the colour of the brew, which works where the tea is part of the presentation. After material, check whether the pot has a removable infusion basket, because that is what makes loose leaf tea practical to serve and to clear between covers. Then size the pot to the serve, single cup or shared table.
