Carrigaline Pottery, founded in 1928 in County Cork, Ireland, is well-known for its collectible souvenir ware, particularly these small 4 ¾" (approx. 12 cm) mini plates. These pieces often served as both commemorative items and functional trinket dishes.

Popular Designs & Features:

You can find several variations of this specific 4 ¾" plate size, typically characterized by a gold-trimmed rim and a scalloped or crinkled edge. Common motifs include: 

Countryside Scenes: The "Countryside Lasses Wash" design or traditional thatched-roof cottage scenes with water pumps.

Irish Symbols: Borders of embossed shamrocks are a signature feature, often surrounding a central image like a map of Ireland or a horse-drawn "jaunting car".

Local Landmarks: Illustrations of Blarney Castle or scenes of traditional fishing and farming. 

Care and Identification:

Back stamp: Look for the green mark on the reverse stating "CARRIGALINE POTTERY CO. LTD. CORK IRELAND," often accompanied by a shamrock cluster.

Maintenance: Due to the gold trim and vintage glaze, these should not be placed in a microwave or dishwasher.

Condition: It is common to find "crazing" (fine surface cracks in the glaze) on these vintage items, which is generally accepted by collectors as a sign of age.
