Is this jadite real or a reproduction?
Some links here are affiliate links — if you buy, the retailer may pay us a commission at no extra cost to you. We have earned $0 from them so far. Here’s how it works.
Check the maker before the colour. Genuine mid-century American jadite is McKee, Jeannette or Anchor Hocking Fire-King, and each made a known set of shapes — a form none of them produced is modern glass whatever its green. Fire-King marks date a piece precisely, and the official 2000 reissue is marked “Fire-King 2000”.
Start with the maker, not the colour
Green is the least diagnostic thing about a piece of jadite. Three American makers dominate the genuine mid-century material, and each has a shape vocabulary.
| Maker | Spelling used | Typical forms | Marks |
|---|---|---|---|
| Anchor Hocking (Fire-King) | Jade-ite | Restaurant-weight cups, saucers, mugs, dinner plates, ovenware | FIRE-KING 1942–52; FIRE KING OVEN WARE 1952–62; ANCHOR HOCKING added 1962–76 |
| McKee | Jadite | Reamers, spice shakers, egg cups, measuring pitchers, the Laurel tableware pattern | Maker marks vary by line |
| Jeannette | Jadite | Mixing bowls, canisters, spice jars, drawer pulls | Maker marks vary by line |
Fire-King dates and mark windows: the Wikipedia entry for Fire-King, read 2 September 2026. Forms and prices: a live CJ product-feed pull of US listings during this run.
The practical rule that follows: if the form is not in one of those vocabularies, the colour does not make it old. A jade-green cake stand, a jade-green canister set in a shape nobody made, a jade-green mug with a modern handle profile — these are new glass in an old colour, and there is nothing wrong with that as long as nobody is charging you for age.
Six tells, in the order you should apply them
- The mark. Read it and date it against the table above. FIRE-KING 2000 is a 2000 piece, and it says so.
- The form. Match it to a maker's known shapes. This catches more modern pieces than the mark does, because modern glass is often unmarked.
- Colour variation. Fire-King's green came from recycled bottle cullet and varies piece to piece. Uniformity across a ‘set’ suggests one modern production run.
- Mould seams and rim finish. Mid-century pressed glass has visible seams and a fire-polished rim. Sharp, unfinished seams point modern.
- Wear on the base. Eighty years of being put down on a counter leaves fine multidirectional scratching on the foot ring. A pristine foot on a ‘1950s’ piece is a question.
- Weight and wall thickness. Restaurant-weight Fire-King is heavy for its size. Decorative modern jade glass is usually lighter.
What genuine pieces were actually listed at
Forty-five rows of genuine McKee and Jeannette jadite were live at a US replacement-china specialist when we pulled during this run. The prices are worth studying because they show what the market values.
| Form | Maker | Listed price |
|---|---|---|
| Drawer/cabinet pull | Jeannette | $29.99 |
| Bread & butter plate | McKee Laurel | $39.99 |
| Dinner plate | McKee Laurel | $49.99–$59.99 |
| Egg cup | McKee | $69.95 |
| Cereal bowl | McKee Laurel | $119.95 |
| Sunkist reamer | McKee | $139.95 |
| 9-inch mixing bowl | Jeannette | $139.95 |
| Spice jar & lid | Jeannette | $179.95 |
| Tea canister & lid | Jeannette | $249.95 |
| Spice shaker with metal lid | McKee | $349.95 |
| Cheese dish & cover | McKee Laurel | $439.95 |
Survival rate, not beauty, sets these prices. A spice shaker at $349.95 is not seven times prettier than a dinner plate at $49.99. It had a corrodible metal lid, lived next to a stove, and was thrown out when the lid failed. Plates were stacked in cupboards and survived.
The reproduction risk tracks that same curve: the forms worth faking are the ones worth $350, not the ones worth $50.

Where people actually get caught
- Buying colour from a photograph. Screen colour is not glass colour. Ask for a shot in daylight against white paper.
- Believing a set is a set. Mixed makers sold as one ‘service’ is common and mostly innocent, but it should be priced as separate pieces.
- Taking ‘Fire King’ in a title as a mark. Sellers use the phrase generically for any green glass. The mark is on the base or it is not there.
- Paying age money for the 2000 reissue. It is marked. Ask for the base.
Frequently asked
How do you tell real jadite from a reproduction?
Start with the maker's mark and the form. Genuine mid-century American jadite is McKee, Jeannette or Anchor Hocking Fire-King, and each made a known set of shapes. A form none of them made is a modern piece whatever its colour.
Was Fire-King Jade-ite officially reissued?
Yes. Anchor Hocking relaunched Jade-ite in a commemorative series in 2000, marked 'Fire-King 2000' and produced for one year only. It is genuine Anchor Hocking and genuinely not mid-century.
Does colour tell you anything?
Less than people think. Fire-King Jade-ite was coloured with recycled green bottle cullet, so the hue varies from piece to piece by design. A perfectly uniform green across a set is a question, not proof.
Is jadite the same as jadeite?
Not in this context. Jadeite is a mineral used for jade jewellery. Jadite is the collector spelling for green opaque American kitchen glass. Searching the mineral spelling returns jewellery.
What are the highest-value jadite forms?
Kitchen items rather than tableware. In our live pull, McKee spice shakers with metal lids were $349.95 and a Jeannette tea canister and lid $249.95, while dinner plates sat at $49.99 to $59.99.

How this guide was made. We research and draft these guides with AI, then a person checks every price, link and factual claim against the source before it publishes. We work this way because it lets us re-verify prices across hundreds of guides in a day, which is what keeps the numbers here current; it does not decide what we recommend. Anything we could not verify is labelled as unverified rather than filled in.
