Margarete Heymann-Marks

"Tea Service" by Margarete Heymann-Marks Löbenstein is a 20th century piece comprising of a teapot, sugar bowl, and creamer. The 1930 piece is made from clay and was fired with  an earthenware glaze. The set is worth between $3,000 to $5,000, however it was sold for $8,125 in 2003 in New York. I really like this pottery because the glaze looks as if it made out of wood. I'm curious to known if she threw this on the wheel or she used a different technique.
