This is very Rare to have a set of four.These were made between 1850-1899. These bowls measure: 5x7 inches. Approximately 2 inches in depth. I attached more information from an 1800's article. There is no chips. One bowl has a line on it. I am not certain it is a Crack because it is smooth and tested it & it holds liquid just fine. The line is on both sides,view photos.One bowl has some sm. brownish spots. There is little notches which are normal for this pottery. This was made in the United Kingdom.
