A ceramic body comprising a crystal phase of aluminum titanate in an amount of 50 to 95% by weight, and a glass phase in an amount of 5 to 50% by weight. The inventive ceramic body may include a second crystal phase, for example mullite in an amount of up to 40% by weight. The glass is an aluminosilicate including, in weight percent on an oxide basis, of 50-90 SiO<SUB>2</SUB>, 1-25 Al<SUB>2</SUB>O<SUB>3</SUB>, 0.5-10 TiO<SUB>2</SUB>, 0.5-20 R<SUB>2</SUB>O, where R is selected from the group consisting of Li, Na, K, Ru, Cs, Fr, and 0.5-20 R'O, where R' is selected from the group consisting of Be, Mg, Ca, Ba, Ra, and wherein the ceramic body includes not more than 2% by weight Fe<SUB>2</SUB>O<SUB>3</SUB>.
