Lately I’ve been teaching myself to read patent office registration marks. These marks, a result of the Copyright of Design Act, appeared on British ceramics made between 1842 and 1883. I‘ve been practicing with a few pieces of ironstone.
Miller’s Pottery and Porcelain Marks contains an excellent section on decoding registration marks. Corners of the printed diamond describe specific characteristics about each piece of pottery. Depending on whether the piece was made between 1842-67 or 1868-83, information within the diamond is presented differently. Here’s what I know about my cup and saucer so far:
All ceramics belong to Class IV. The “Lobelia” pattern of my ironstone cup and saucer was registered on June 19, 1845 by G. (George) Phillips of Phillips’ Pottery at Longport. The parcel number shows how many pieces were included in the registration. In this case, it was only 1. To learn more about Phillips’ Pottery, click here.
I picked up this set of plates from a Boston antique dealer. The plates were made by the Anthony Shaw Company in a pattern called “Peruvian Horse Hunt.”
It seems that there are many horse scenes included in this pattern. I think that the number 9 on the bottom of my plates denotes this lasso scene.
The registration date for these plates is August 8, 1850. You can also find registrations of “Peruvian Horse Hunt” in different colors, including mulberry and a green/brown combination. The 1850 date is the earliest I’ve seen so far.
