Product title: Mara Ceramic Stoneware Southwest Butter Dish with Lid
Product description: Listing is for a Butter Dish with a Lid. This Butter Dish and Lid Dimensions are 6.5 inches x 3 inches x 2.5 inches. Mara, an accomplished painter, sculptor and ceramicist, studied engraving with the famous artist Alfredo Zalce, who painted many portraits of his lovely artist protg. After studying art in London, she began working with high-temperature ceramics and created wonderfully unique glazes for her pieces. She then went on to study with the Italian ceramist, Bruno Terese, in Italy. Mara has had numerous expositions of her original pieces in Europe, the United States and Mexico. "She has developed a fine sensibility in schematic and precise line drawings. Ceramics is no easy medium for precise line drawings, yet Mara has mastered her technique with brush and stylus and has been able to portray her life experiences with unrivaled naturalness. We see her universe on parade in all of her pieces, whether they be vases or plaques. Flowers, birds and geometric designs all represent her personal vision and display her unique perceptions of the world." Alfredo Zalce, May 1994 Sadly, after a long illness, Mara passed away in November 2007. Since Ceramica Mara has always been an extended family operation, production of her fine works has continued. Mara's husband, daughter and loyal apprentices have consistently carried out day to day production. Her husband Mariano, an architect, artist and Ceramica Mara business manager, is passionate about continuing Mara's legacy. Her daughter Alexandra, artist and history professor, has also stepped in to help the family make a seamless transition in the continuation of the fine production of Ceramica Mara.
