An American egg-shaped porcelain Passover salt water dish with a matching ladle from circa 1920 reflects American artistic trends of the 1920s, blending traditional Jewish themes with modern aesthetics.

The early 20th century saw significant Jewish immigration to the United States, particularly from Eastern Europe.

Porcelain was a popular material for decorative and functional items during this period, known for its delicate and refined qualities. American manufacturers were producing high-quality porcelain pieces, a material prized for its beauty and fine texture, and often influenced by European styles.

This lovely dish rests on three legs painted with foliate designs, outlined with gold-lined patterns, applied to the underside of the egg-shaped container. The opening at the top is jagged and resembles a cracked egg, with a large ladle resting in its mouth. Intricate foliate designs with a crowned plated egg and "ZALTZ VASSER" are painted in Yiddish on one side. The first verse of the "Mah Nishtana" is painted in Hebrew on a book design on the other side and "Seder Salt Water" above it with similar painted designs. 

The dish’s egg shape is symbolic, as the egg is an important element of the Passover Seder, representing renewal and rebirth. The saltwater dish is used during the Passover Seder to hold salt water, which symbolizes the tears shed by the Israelites during their slavery in Egypt.

The dish showcases the skills of American artisans, incorporating elements of Art Deco and other contemporary design movements. The representation of the rich traditions of Jewish ritual and the artistic influences of  America in the early 20th century adds to the dish’s significance.
