Anchor Hocking Block Optic Uranium Depression Glass Pitcher - Art Deco Green Vaseline Glass
A spectacular showpiece for collectors of uranium glass and Depression Glass enthusiasts.
This exceptional large pitcher showcases the iconic "Block Optic" pattern by Anchor Hocking, one of America's most celebrated Depression Glass manufacturers. Produced between 1929 and 1933, this piece represents the pinnacle of Art Deco geometric design—and it has a spectacular secret: it's uranium glass that glows brilliant green under UV light. Very rare to find one in this larger size and in such excellent vintage condition.
Why You'll Love It
This is a substantial piece at 1,227g with a generous 2.36L (80oz) capacity—perfect as a statement centrepiece or the crown jewel of your Depression Glass collection. The uranium creates the distinctive yellow-green colour and that mesmerising glow that collectors treasure under blacklight. The bold Block Optic pattern with its geometric facets catches and refracts light beautifully, creating visual drama whether displayed empty or filled. This feature adds both scientific fascination and serious collectible value to an already stunning piece of Depression Glass history.
The Story
Anchor Hocking Glass Company was one of the premier American Depression Glass manufacturers, and their Block Optic pattern epitomises Art Deco design with its bold geometric forms and angular facets. The pattern's architectural quality reflects the Machine Age aesthetic of the late 1920s and early 1930s, when streamlined modernism was transforming American design. The uranium oxide content makes this true vaseline glass that fluoresces dramatically under blacklight—a feature that adds both scientific wonder and collectible appeal. Produced during a brief window from 1929 to 1933, large pitchers like this are increasingly scarce among collectors.

Excellent vintage condition for a piece over 90 years old—looks like it's never been used! The glass retains its clarity and the pattern remains crisp and well-defined. No chips, cracks, or restoration. Minimal bottom wear, consistent with age and use. Visible mould seams as expected. A pristine example that's ready to display or add to your collection.

Age of an Item
Antique: An item that is at least 100 years old.
Vintage: An item that is at least 20 years old but less than 100 years old and is representative of its era.
Retro: A newer item designed in the style of a past era. It is not from that era but is a modern homage to it.
Condition of an Item
Mint: As new, with no signs of wear.
Excellent Vintage Condition (EVC): Shows minimal signs of wear through use but is not perfect.
Very Good Vintage Condition (VGVC): Shows some signs of age and use but is still in good overall shape.
Good Vintage Condition (GVC): Shows clear signs of wear, use, and age.
Perfectly Imperfect: This is not an official term. We've adopted it for the purposes of The Timeless Edit because we believe damaged items still have value. Our definition of Perfectly Imperfect is if an item has visible damage but remains beautiful as a decorative piece or suitable for use in a different capacity from that for which it was originally designed.
Common Flaws found in Antique and Vintage Items
Crazing: Crazing is the existence of web of fine cracks that only occurs in the glaze layer of Fine Bone China and porcelain. It is a normal occurrence, particularly in older items.
- Clean Crazing: The cracks are clear, without any staining from food, moisture, or other contaminants. Clean crazing can be used as an intentional decorative design element.
- Stained Crazing: This occurs when food particles, bacteria, or other contaminants get into the cracks over time, causing them to darken and become visually conspicuous. Items with stained crazing are not recommended for use with food but are still great for use as a decorative piece or other practical function.
Flea Bite: A flea bite is a tiny, pin-sized chip or nick in the surface of an item. It is a common form of imperfection in older items, especially glass.
Bottom Wear: This is common in older items, especially glass, and is often an indication of age. Wear to the base of an item is caused by everyday use over time and includes scratches, scuffs, shallow chips, flakes, and flea bites.
Chip: chips are considered either shallow or deep. A shallow chip is typically inconspicuous. A deep chip is large enough to be immediately apparent.
Flake: a small and shallow chip which breaks the surface of an item.
Scratch: a mark which compromises the surface of an item, and which feels raised, rough or sharp to the touch. Not to be confused with Straw Marks and marks which can occur during the manufacturing process.
Hairline Crack. This is a narrow and tight break going through glaze and porcelain body and is visible from both sides of the item. It is not always immediately obvious and can be missed on first inspection. Generally, a hairline crack does not affect the integrity of the item.
Water Mark/Stain: patches, ridges, deposits and clouding on glass caused by water left standing in the vessel for a lengthy period. Such stains can’t be removed.
Air Bubbles: Air bubbles in hand-blown glass are a natural result of the traditional glassmaking process, where air becomes trapped in the molten glass during its creation. They are often seen as a sign of authenticity, indicating the item is handmade and unique, rather than a defect. While a small number of bubbles is generally acceptable, a high concentration of bubbles may indicate fragility. There are exceptions though. In some cases, air bubbles are an intentional decorative feature where artists have used specific Molds or techniques to control their appearance. Also, air bubbles are found in Depression Glass due to its mass production method, where the glass was quickly moulded with little concern for perfection. These bubbles are a common characteristic that signifies authentic pieces.
Maker’s Miss: This is an unintentional inclusion or air bubble in the item caused or overlooked by the glass blower or maker in the manufacturing process.
Firing Flaw: This is original flaw cased during the firing process. Examples include pinholes or blisters in the glaze, grit stuck to the glaze, stains caused by an impurity in the porcelain and shrinkage cracks that have opened during the drying or firing process. This is not considered damage.
Straw marks: These are marks on the external surface of glass that look like fine lines or even scratches. They occur when molten glass is cut with shears, and the resulting mark doesn't fully smooth out before the glass cools and sets. They are not considered damage but are instead a common characteristic of old, handmade, or machine-pressed glass. Unlike a scratch, straw marks feel smooth to the touch. Straw Marks are commonly found in Depression and Carnival Glass.

Identifying Authentic Anchor Hocking
Anchor Hocking pieces are typically marked with moulded or stamped marks on the base. Common marks include "Anchor Hocking," "AH," the anchor-over-H logo, or "Fire-King" for that specific line. Some pieces include pattern names or numbers. Earlier Depression glass pieces may be unmarked but can be identified by distinctive patterns and colours. The quality of moulding, weight, and characteristic colours (particularly the jadeite green and Royal Ruby red) are reliable indicators of authenticity.
Notable Patterns & Lines
Anchor Hocking's most collectible lines include Fire-King jadeite restaurant ware, turquoise blue pieces, and decorated patterns like "Wheat" and "Philbe." Depression glass patterns such as "Mayfair" (pink and blue), "Princess" (green and pink), "Royal Ruby" (deep red), and "Forest Green" are highly sought-after. The "Bubble" pattern in various colours, "Moonstone" with its opalescent hobnail design, and "Wexford" pressed glass are also popular with collectors.
Caring for Your Anchor Hocking Glass
These American treasures deserve thoughtful care. While Fire-King was designed for oven use, vintage pieces should be hand washed with warm water and mild detergent to preserve their condition. Avoid harsh chemicals, abrasive scrubbers, or extreme temperature changes. Handle carefully, particularly pieces with delicate edges or handles. Display away from direct sunlight to prevent colour fading, especially with pink and green Depression glass. Store with care, using soft padding between pieces. With proper care, your Anchor Hocking glass will continue its journey through homes for generations to come.
At The Timeless Edit, we celebrate Anchor Hocking glass as part of our commitment to circular luxury – honouring American craftsmanship, design heritage, and giving beautiful vintage pieces a cherished second chapter in homes that will treasure them.
