Heavy Grape - Imperial
Imperial's Heavy Grape pattern is distinguished by a center cluster of grapes, leaves and vines surrounded by a quilted diamond effect around the edge. The back has a simple fluted thumbprint design and a collar base with a rayed star. Shown above left are a chop plate and an eight-inch plate. To the right is a round flared bowl.

Heavy Grapes many shapes are; 5-6 inch small bowls, 7-8 inch medium bowls, 9-10 inch large bowls, single handled nappies, rare 6 inch plates in marigold, 7-8 inch plates, rare 9 inch plates, and 10-11 inch chop plates. The large bowls, when combined with six small bowls, would form a berry set. The 7-8 inch plate is seen more frequently than any other shape.

Bowls and plates are found in clambroth, green, Helios, lavender, lime green, marigold, purple, smoke, teal, and white. Purple is the most available color. Amber, green, marigold and smoke can be found with some regularity. Other colors would be scarcer.


The photos above show the difference between bowls with scalloped edges and those with smooth edges. Most Heavy Grape pieces have a scalloped edge. Bowls that are flared have this scalloped edge. However, bowls that are ruffled have a smooth edge.

Smooth edge bowls that are ruffled may or may not have the quilted pattern on the outer edge of the interior. The two bowls to the left, in smoke and amber, are flared and show the scallop edge and quilted design. At the right is a small bowl in blue, a rare color for Imperial. Note that this bowl is ruffled with a smooth edge and also lacks the quilting. This non-quilted variation is found in both bowls and plates.

The photos above show the difference between scalloped edge plates and smooth edge plates. Smooth edge plates are rather rare and only seem to appear in the 8 inch size and only in marigold. The last photo, to the right, shows the exterior fluted thumbprint design typical of all bowls and plates.
Punch sets are hard to find. They come in green, purple and marigold. Even the punch cups are rare, especially this electric purple example.
To the left is a scarce single handled nappy.

Dugan made a pattern also called Heavy Grape that has a leaf in the center and does not have the quilting effect.

Lenox/Imperial, Fenton and Smith have reproduced this pattern.
