Royal Doulton Lambeth Tazza with Glazed Stoneware Bowl

• Salt Glazed - Salt glazing involves throwing salt into the kiln when it is at its highest temperature, usually around 2,300 to 2,400 degrees Fahrenheit (1,260 to 1,320 degrees Celsius). The salt vaporizes and forms a glaze on the surface of the pottery, creating a range of effects depending on how the salt is applied and the firing conditions. This glazing method was first developed in Germany in the 15th century and quickly became popular throughout Europe and North America. It was particularly popular for making stoneware pottery, such as jugs, crocks, and other utilitarian objects.
  
  Salt glazes can produce a range of colors, including gray, brown, blue, and even pink or purple in some cases. The texture of the glaze is typically rough and pebbled, with a matte or satin finish. The process of salt glazing can be unpredictable, with variations in temperature and salt application leading to subtle variations in the finished product.
  
  Salt glazing is still used by potters and ceramic artists although it is less common than it was in the past.
• Circa - A Latin term meaning 'about', often used in the antique trade to give an approximate date for the piece, usually considered to be five years on either side of the circa year. Thus, circa 1900 means the piece was made about 1900, probably between 1895 and 1905. The expression is sometimes abbreviated to c.1900.
• Tazza - A tazza is a shallow saucer-like dish, either mounted on a stem and foot, or on a foot alone, used for drinking or serving small items of food. The word is derived from the Italian for "cup", plural tazze. Tazza are usually found in silver, ceramics or glass.
• Art Union of London - Art Unions were organisations that functioned to promote and fund works of art. The members would pay an annual subscription, which would be used to purchase works of art, and these would then be distributed among its members by means of a ballot.
  
  The Art Union of London was established in 1837 and by the 1840s was distributing art to the value of £9,000 each year.
  
  The works purchased ranged from paintings which had been exhibited at the Royal Academy and in galleries to prints and smaller pieces including commissioned Parian wares, medals and bronze statuettes.
  
  The membership numbers of the Art Union of London remained strong until the 1890s when they began to decline, and the Union was wound up in 1912.
