Satin Glass
From Melting Pot Wiki
Hobbs, Brockunier and Company of Wheeling, W. Va., was the main producer of satin glass (Similar glass was made in England and during the same period). A dull matte finish made by submerging the vessel in a corrosive acid or in the fumes of acid. The process was synonymous with "frosting" of fancy art made in the United States during the last half of the 19th century.
