The Homer Laughlin China Company of Newall, West Virginia opened for business in 1871.
From then to now, they have produced dinnerware (and even kitchenware), and many of the lines are still popular to this day. Examples of these lines are Fiesta, Virginia Rose, Harlequin, Rhythm, Nautilus, Swing, Riviera, and even Century.
Most of the dinnerware is marked by Homer Laughlin, so identifying a manufacturer is not a problem. Some of it features the name of the pattern as well, which helps out a lot. The HLC trademark is usually followed by a number series, the first two digits will indicate the year. So if you do run across a Homer Laughlin piece that doesn't have the name of the pattern on it, you can most likely narrow it down with the year mark.
I'm partial to the restaruantware that Homer Laughlin made (a piece of it can be seen in the first two pictures). I've always thought that with the piece being made for extra ware and tare, I don't have to be so delicate with it.
You can see all of the Homer Laughlin pieces in my Etsy shop here. What kind of finds do you have in your collection?
