Mr. Pruden establishes The Harrison Pottery at 316 Market Street (now Harrison Ave. where La Rosas stands).  He makes crocks, containers and other useful pieces from clay found in the area.  The pottery changed hands twice more that we know of- owned and operated by Frank Rupp who was killed in the gas explosion in the Harrison Town Hall, then taken over by his son William Rupp.

(From 1899) WILLIAM RUPP was born in Cincinnati February 2, 1854, son of Frederick and Catherine (Oehlar) Rupp, natives of Germany. His father first located in Cincinnati. He was a potter by trade, a vocation he followed for some time in the city, when he moved to Harrison, Ohio, continuing there in the same business until his death, which occurred March 8, 1878, in a gas explosion. His wife died in 1884. They were the parents of nine children, six of whom are living: Maggie, Catherine, Frederick, William, Elizabeth and Anna.
The subject of this sketch spent his early life in Cincinnati, receiving his education in the public schools. When he reached his majority he became a partner with his father, and has since continued in the business, which has greatly increased. Socially, Mr. Rupp is a member of the Knights of Pythias, and politically he is a Republican. He has been township clerk one term, the only Republican elected in fifteen years; was a member of the fire department eleven years, chief two years, and assistant one year, and served as treasurer for ten years; on April 2, 1894, he was elected corporation treasurer by a handsome majority. Mr. Rupp is also a musician, and has organized a well-equipped band among his employes, which is favorably known in this section of the country as Rupp's Cornet Band.
