In the contemporary era of carnival glass, which spanned from the mid 1960s to about 2010 when Fenton Glass closed, many glass companies made miniature carnival pieces. To be classified as a miniature, the piece must represent a larger item but be made in a smaller size. A toothpick holder would not be considered a miniature piece even though it is small because it is the correct size for a toothpick holder. Water sets and punch sets are large in nature and thus can be made in a miniature size.
Club Souvenirs Miniatures
Miniatures were probably made because they were less expensive to make. Several clubs had miniatures made as their club convention souvenirs.

The American Carnival Glass Associaiton (ACGA) made miniature Morning Glory tankards for its convention souvenirs for four different years. These were modeled after Millersburg's classic era tankards. And for one year they made a miniature Hobstar and Feather punch set also modeled after a Millersburg pattern.
The Encore Glass Club had several miniatures made for their conventions. Dorothy Taylor had molds made and commissioned glass companies to make the pieces. Above are an Inverted Peacocks water set, a Trout punch set and a God and Home water set. See Encore's page for more information about Encore souvenirs.
The International Carnival Glass Association (ICGA) made miniature Town Pumps for its convention souvenirs for six different years and also made a miniature Inverted Peacocks water set for one year.
Weishar Glass and Wetzel Glass
Both the Weishar Glass Company and the Wetzel Glass Company made miniature water sets. These smaller glass companies had smaller furnaces and often focused their work on small pieces. Weishar made the miniature Moon and Stars water set in several colors. Chocolate Opal is shown here to the left.

Wetzel made the miniature Hobnail water sets in several colors. When Wetzel stopped making pressed glass, they sold their molds to E.E. Collectibles. Pieces were then marked "E.E.". Summit Art Glass pressed E.E. pieces. Pictured to the right are vaseline opal, blue slag and red. The blue slag is marked "Wetzel" while the vaseline opal and red are marked "Wetzel E.E."

Grape and Cable and Cherry and Cable - Mosser Glass
Mosser Glass made several shapes in its line of miniature Cherry and Cable. Shown above are a water set, a table set and a punch set. Other shapes include a miniature cookie jar. Typically found in purple although green is known. Cherry and Cable was a classic era pattern of Northwood's. All miniature pieces of Cherry and Cable are contemporary.
Mosser also made miniature versions of the Grape and Cable pattern made in the classic era by Northwood. On the left is a Mosser miniature creamer and sugar in the Grape and Cable pattern complete with box. The sugars are often mistaken for toothpick holders. In the center is the accompanying miniature butter dish. Mosser also made a miniature Grape and Cable water set.
Lamb Miniatures - Imperial and Boyd
Imperial made the miniature covered butter, open sugar, and creamer (about 3 inches tall) in purple in 1981 when the company was owned by Lenox. These pieces are all marked "LIG" and many have the "Lennox Imperial" black paper label. Imperial closed shortly thereafter. Boyd then acquired the molds and made them in contemporary colors including yellow and ice blue. Boyd included a fourth piece, a covered sugar, and sold them together in a box.
File and Fan Miniatures - Westmoreland

Westmoreland made the toy File and Fan punch sets and table sets in the early 1900s. Below are pages from Westmoreland's 1912 catalog. These molds were then reused in the contemporary era to make carnival glass sets. Some are marked Rosso, as is the amethyst set shown here. Rosso is a distributor of glass and commissioned to have pieces made. LEVAY had them made in a variety of contemporary colors including the red above. During the Classic Era of carnival glass, Westmoreland used this mold to make a small compote also called File and Fan.
Miscellaneous Miniatures
Little Joe, Westmoreland and Summit - Westmoreland made this toy water set in 1977 for Levay Glass. It was limited to 500 pieces in purple. The pitchers are 4 inches tall and the tumblers are 2 inches tall. In 1979, Levay Glass had another 500 pieces made in the Red shown here. Examples in blue, green and vaseline are also known. Paneled Grape, Fenton - Paneled Grape was made in several full size shapes. This miniature water set comes with a pitcher and four tumblers. They are signed Fenton.
