Good information to know when you’re trying to identify real fiestaware.
(From Homer Laughlin China Website)
The method of placing our identification mark on a piece is determined by the way that the piece is made. Most of our hollow pieces (mugs, bowls, pitchers, vases, etc.) are formed in a mold and our mark is carved into the mold, leaving an impressed mark on the piece. Flat items such as plates are formed by a different method and an impressed mark cannot be placed on the bottom of the piece. In this case, we use an ink stamp which is applied to the unfired piece, beneath the glaze. Please note that on some of the darker glazes it is very hard to see the back stamp.
ADDITIONAL HANDY INFORMATION
Many of the early pieces of fiesta weren’t marked. The ink stamp “GENUINE fiesta” came later, which explains why so many plates aren’t marked, although the lower case “fiesta HLC USA” or “fiesta MADE IN USA” was molded and indented into many of the first pieces. There were quickly modifications to some pieces of the line (the sugar bowl, teacups, utility trays, the creamer, the nesting bowls, the ashtrays- they all underwent slight modifications early on). These early pieces are highly coveted with serious collectors.
