Fenton’s hobnail glass has been a staple of American glassmaking for over a century, and you’ll know it if you see it: It’s instantly recognized by its raised, textured surface. But there’s a significant difference between some early and late patterns.
Between 1911 and the late 1930s, the company refined its look and introduced a range of products, including swung vases and opalescent glass. This guide will show you the standout patterns from that era, including their size ranges and colors.
1April Showers (#412)
The April Showers pattern first debuted in 1911 on short and tall swung vases. It features a textured surface similar to Fenton’s Rustic line and Northwood’s Tree Trunk pattern. But unlike the evenly spaced bumps on Rustic (which will be shown later), April Showers vases have a more irregular layout. Some examples even incorporate the Peacock Tail design inside the vase.
- Sizes: 5-inch squat vases to over 15 inches tall
- Colors: Golden, Green, Royal Blue, Violet, White, Topaz, and Red
- Rarity: Availability ranges from moderately available to extremely scarce
2Rustic (Maryland)
The Rustic series began in 1911 and produced a variety of hobnail vases in multiple heights and finishes. Vases range from 7 to 22 inches, and the term “Maryland” was used by Fenton to identify a specific vase shape within the Rustic series.. Smaller pieces around six inches typically belong to Fenton’s later Hobnail line (c. 1939), introduced decades after Rustic.
- Sizes: 7–9″, 10–15″, and 16–22″
- Colors: Golden, Green, Royal Blue, Violet, Red, White, Lime Green Opal, Peach Opalescent, and Purple
- Rarity: Most colors are common, but unique opalescent versions and reds are significantly rarer
3Heavy Hobnail (#517)
Also emerging in 1911, Fenton’s Heavy Hobnail pattern features short, large-knobbed vases that were made by skipping the swinging process typically used in Rustic molds. These pieces are particularly hard to find today.

- Sizes: Approximately 5–7 inches
- Colors: Violet and White
- Rarity: Very uncommon and expensive
4Fenton Lamps
During this early production era, Fenton produced lamp bases and components for other companies to assemble. The 1931 catalog captures the breadth of hobnail-influenced lamp styles that circulated during this time.

- Sizes: Lamp bases and components for other manufacturers, typically 6–10″, with some student-style lamp bases up to 12–14″.
- Colors: Rose, Crystal (clear), and Green, as documented in the 1931 catalog.
- Rarity: Considered rare since most early pieces had limited runs before Fenton launched its own full hobnail lamp line
5Milk Glass
White milk glass items first appeared in Fenton’s records in 1924 but were only produced steadily after 1933. The Great Depression pushed Fenton to reuse older molds—like Mikado, Milady, and Apple Tree—to create new designs. By 1938, swan novelties and other pieces in milk glass laid the foundation for what would become the iconic hobnail line.
- Shapes: Swan novelties and small decorative pieces, later inspiring hobnail shapes
- Color: White milk glass wasn’t produced regularly until 1933
- Rarity: Early white milk glass pieces from the 1920s and early 1930s are rare, particularly items molded from discontinued designs and pre-hobnail novelties like the swans
6Hobnail Opalescent
Although opalescent effects were attempted earlier, large-scale production didn’t take off until 1938. That year, Fenton released substantial amounts of Spiral Optic glass in French opalescent, Blue Ridge, Cranberry, Green, and Stiegel Blue.
By 1939, when Fenton introduced the official hobnail line, hobnail opalescent colors became a focus. With resources dedicated to these popular patterns, production of non-opalescent items declined. These late-1930s designs set the stage for Fenton’s hobnail dominance in the mid-20th century.
- Shapes: Squat vases (~5″), mid-size vases (10–12″), and large swung vases over 15″ tall
- Colors: Golden, Green, Royal Blue, Violet, White, Topaz, Red
- Rarity: Moderate availability for common sizes and colors; extremely scarce in oversized swung forms and rarer shades like Red and Topaz
7Cameo Opalescent
Though produced briefly, this beige-toned opalescent finish is an early trial in Fenton’s color experimentation. By 1916, pieces such as hexagonal sugar and creamer sets appeared. In later years (1979–1982), Fenton revived this tone, using it in hobnail and spiral optic shapes.
- Shapes: 6″ bell, compact 4¼″ mini bud vases, and larger 8″ baskets
- Colors: Amber Opalascent
- Rarity: Relatively scarce with a brief production run of just a few years
