Ceramarte Ltda.
Rua Adolfo Konder 70, Rio Negrinho, Santa Catarina, Brazil
The company founders, Klaus and Maria Erdmuthe Schumacher settled in Rio Negrinho in 1952 and by 1956 had started a small ceramic's company, with the emphasis on quality products. By the 1970's they had built up a lucrative market in the United States through various brewing companies. A new phase began in 1998 when "Ceraflame" cookware was introduced. Ceramarte is probably the largest contract supplier of promotional brewery and special commemoration steins still in existence. Hundreds of different promotional stein designs have been ordered for the following companies: Avon, Budweiser, Anheuser-Busch, Stroh, WEBCO, Schiltz, Hamm's, Disney, Coca Cola and others.
