Among his works are La forma nuziale in sacrestia; La tombola in Campielo a Venezia; Una scena di burattini in un educanciatu; and La Ninetta. The art critic Luigi Chirtani, when the painting was displayed at the Mostra Nazionale di Venezia, described it as Beautiful, flattering, pretty, caressed, cleaned, polished, laundress in a painting by Mr. Blaas, the favorite portraitist of great Venetian aristocrats, dressed in gala satins, shining jewelry, hairstyles of the rich.
His colorful and rather theatrical period images of Venetian society, e.g. On the Balcony (1877; Private Collection), were quite different compared to delicate pastels and etchings of the courtyards, balcony and canals of modern Venice.
