At the Tang Museum at Skidmore College, ‘Kathy Butterly: Assume Yes’ surveys more than thirty years of work by one of the most inventive artists working in ceramics today. Butterly is known for small-scale sculptures that are technically daring, expressive, and often witty. At the Schick Art Gallery in Skidmore’s art building, ‘Earthbound’ brings together work by eleven contemporary ceramic artists. Their work ranges in techniques and aesthetic approaches from figurative to abstract, and from functional to fantastical.And opening Saturday at The Hyde Collection is ‘Toshiko Takaezu: Voices of Abstraction.’ Takaezu was known for her ceramic forms and expressive glazes, and the exhibition places her work in dialogue with painters including Sam Gilliam, Adolph Gottlieb, and Lee Krasner.
