The Crystal Guide: Lalique, Daum & William Yeoward
Lalique, Daum, and William Yeoward are all called crystal makers, and that word hides how differently they work. One molds crystal into sculpture and frosts the surface. One packs colored crystal into a plaster mold that must be broken to release the object. One blows and cuts stemware by hand. Here is what crystal is, how each house makes it, and how to look after it — whether you are buying a sculpture or glasses for the table.
What "crystal" actually means
Glass, crystal, and lead crystal
All crystal is glass. What separates the two is an added mineral oxide, historically lead oxide, which does two useful things: it raises the refractive index, so light bends harder inside the material and separates into color at a cut edge, and it softens the batch enough to be cut deeply. It also adds weight.
Long-standing European convention reserves the term full lead crystal for glass containing at least 24 percent lead oxide. Below that, it is sold as crystal, crystallin, or half-lead crystal — still cuttable, still bright, simply less dense. Many modern houses use barium, zinc, potassium, or titanium oxides instead.
Few makers publish their batch composition, so be skeptical of any percentage a brand has not stated itself. Daum is one exception: the house describes its own crystal paste as containing close to 30 percent lead.
The three tells: weight, ring, and refraction
- Weight. Lead crystal is noticeably denser than soda-lime glass of the same size, and the difference is obvious once you have handled both.
- Ring. A thin-walled crystal glass, tapped gently at the rim, gives a sustained tone rather than a flat click.
- Refraction. Held to a bright window, a cut edge in crystal throws prismatic color; ordinary glass mostly throws white light.
The ring test is reliable only on thin, blown, open forms. Thick castings, molded sculpture, and satin finishes damp the tone almost entirely, which covers nearly all of Lalique and effectively all of Daum. A Daum sculpture will not ring; nothing is wrong with it.
Lalique: molded crystal and the frosted surface
A jeweler who turned to glass
René Lalique (1860–1945) was famous first as an Art Nouveau jeweler. He came to glass in middle age, and what made it a business was his work for the perfumer François Coty, which established that a scent could be sold in a bottle worth keeping. In the early 1920s he founded his glassworks at Wingen-sur-Moder in Alsace, where the house still produces.
The most useful fact for dating a piece is what followed his death in 1945: his son Marc took the house from glass into crystal. Bacchantes makes it concrete. Designed in 1927 and first produced in glass, it has been made in crystal since 1947 — same model, different material.
Lost wax, press-molding, and the satin finish
Lalique works in two registers. Cire perdue, or lost wax, is used for unique and strictly limited pieces: the mold formed around the wax model is destroyed to release the object, so the process caps the edition. Press-molding allows a design such as Mossi — a satin body carrying ninety-six raised cabochons, designed in 1933 — to be made in series for decades.
The visual signature is the contrast between polished-clear and satin-frosted areas on one body. Light passes cleanly through the polished zones and is scattered into a soft white by the frosted ones, so the modeling reads as sculpture rather than surface decoration. The same logic governs the swirled walls of Tourbillons, designed in 1926, and the figures and statues.
Marks and dating
As a general rule, a piece marked "R. LALIQUE" was made in René Lalique's lifetime, and postwar production carries "Lalique France," usually acid-etched somewhere discreet. Treat that as a starting point, not a verdict: signature study is a specialist field, marks have been added and altered, and forgeries exist. If provenance matters, current production is the straightforward route. Every piece we sell is new, first-quality, and sourced directly from the manufacturer or its official U.S. distributor — never from secondary markets.
Where to begin
For a first piece, Bacchantes is the reference point: a frieze of nude dancers, priestesses of Bacchus, circling a conical body. The limited editions are where the lost-wax work appears. For Lalique on the table rather than the console, the 100 Points line, developed with the wine critic James Suckling from 2012, is the bridge.
Daum: pâte de verre, and why the editions are finite
Nancy, 1878
The Daum glassworks was established in Nancy in 1878 and made utility glass before Jean Daum's sons, Auguste and Antonin, turned it into a central workshop of the École de Nancy. This is the Art Nouveau world René Lalique emerged from: the two houses are cousins, not rivals. Pâte de verre has been the identity of the house since 1968.
How pâte de verre is made
A sculptor's model is made and a hollow mold taken from it. Hot wax is poured in, cooled, released, and reworked by hand until it is a perfect copy. The wax model is buried in refractory plaster and fired; the wax runs out through a channel cut for it. What remains is a plaster mold, an exact negative of the object — and there is exactly one of it. Crushed crystal in the chosen colors is packed in by hand and fired. Once cool, the plaster is broken away, and the piece is cold-worked, polished, and signed.
Two consequences follow, and they are the point. Because the mold is consumed, output is inherently limited; edition size is not a marketing decision. And because the color is packed in as solid material before firing rather than applied to a finished surface, the gradients run through the glass. That is why a Daum piece appears lit from within, and why its color cannot wear off.
Editions and artists
Where a design is issued as a numbered limited edition, the number of examples is fixed at the outset and each piece carries its number. Daum has worked with living artists for over half a century: the work with Salvador Dalí began in 1968, and it continues with Richard Orlinski and the floral work of Emilio Robba.
The botanical pieces show graduated color to best effect and are the easiest introduction: Rose Passion and Arum. The decorative objects and tableware show how far the technique stretches.
William Yeoward: hand-blown, hand-cut, and made for the table
A designer's revival of Georgian cutting
William Yeoward Crystal came into existence in 1995, from a collaboration between the London designer William Yeoward — already working in furniture, lighting, and fabrics — and Timothy Jenkins, third generation of a family crystal business with long experience of the European glass trade. Both collected antique crystal and thought little of what was then being made; their first collection was shown in London that autumn.
The design source is explicit: English and Irish cut glass of the eighteenth and early nineteenth centuries, and the Georgian repertoire of deep miter cuts, flutes, and printies. Every piece is handmade by much the same methods used more than a century and a half ago. A full-size drawing is produced by hand, a wooden mold made from it, molten crystal blown into that mold, and the cutting and engraving done by hand. No two examples are dimensionally identical.
Patterns, not seasons
The range is organized by named pattern — Fern, Corinne, Vanessa, Pearl and others — rather than by collection year, so a household can add to a pattern over decades instead of chasing a discontinued season. Hence its strength as a registry choice.
That is also the real difference from the other two houses. Lalique and Daum make objects you look at; William Yeoward makes objects you use: stemware and barware, champagne glasses, cocktail glasses, vases, candlesticks. The house also produces bone china, and the full range is designed to sit together on one table.

Buying and collecting
Three things matter when you examine a piece. Chips are easiest to miss on a rim: run a fingertip round it rather than trusting your eye. Flea bites are the tiny crescent-shaped nicks at high points and cut edges, usually from contact with another piece. Sickness is the permanent internal clouding in old decanters, caused by wine residue and standing moisture.
The antique markets for Lalique and Daum are deep and specialist. Current production removes the question: the mark is correct because the maker applied it, the condition is as-made, and the piece arrives in the maker's own presentation box. Keep your receipt and that box — it is purpose-made for the object, and it is what you will want if the piece has to travel.
Caring for crystal
Hand-wash, always
A dishwasher will ruin fine crystal, and the damage is not reversible. Detergents are strongly alkaline, and that chemistry combined with sustained heat and agitation microscopically roughens the surface. The glass then scatters light instead of transmitting it, and takes on a permanent gray haze no polish will lift.
Wash by hand, one piece at a time, in warm rather than hot water with a little mild detergent. Line the sink with a rubber mat, take off rings and watches, and never let two stems knock together. Hold a wine glass by the bowl, not the stem: twisting one against the other is how stems break.
Thermal shock, drying, and storage
Crystal dislikes sudden temperature change, so never pour boiling water into a cold glass. Dry with a soft lint-free cloth, supporting the bowl in one hand. Store stemware upright on a padded shelf, not rim-down: the rim is the thinnest part of the glass, and resting the piece's weight on it invites chips.
Decanters and carafes
Rinse a decanter with warm water immediately after use, before anything dries. For a stubborn deposit, use dedicated cleaning beads or a soft long-handled brush. Never use bleach or abrasives, and never a dishwasher. Avoid effervescent cleaners such as denture tablets on gilded or hand-painted pieces, since they lift decoration.
Drying is where most decanters are lost. Invert the piece over a drying stand until the interior is completely dry — this can take a day — and only then replace the stopper, since trapped moisture is what produces sickness. The same applies to carafes and to any narrow-necked vase that holds water.
Frequently asked questions
What is the difference between crystal and glass?
Crystal is glass with a mineral oxide added — historically lead oxide, though barium, zinc, potassium and titanium are also used. The addition raises the refractive index, so the material separates light into color at a cut edge, and softens the batch enough to be cut deeply. Crystal is also heavier.
Is all crystal lead crystal?
No. European convention reserves "full lead crystal" for glass containing at least 24 percent lead oxide, but many modern formulas use barium, zinc, potassium, or titanium oxides instead, particularly for drinking glasses. Most makers do not publish their composition.
What is pâte de verre?
Crushed crystal, colored with metal oxides, packed by hand into a refractory plaster mold and fired, after which the mold is broken away to release the piece. It is Daum's signature technique, and the reason the color runs through the object rather than sitting on its surface.
Why is Daum limited edition?
Because the process consumes its own tooling. The plaster mold is formed around a wax model that melts away in the kiln, and the mold itself must be broken by hand to release the finished piece.
How can I tell whether a Lalique is old?
As a general rule, "R. LALIQUE" indicates a piece made before 1945, in René Lalique's lifetime, while postwar production is marked "Lalique France." Marks alone are not proof: signatures have been added and altered, and antique Lalique is a specialist field where independent verification is worth paying for.
Can crystal go in the dishwasher?
No. Alkaline detergent, combined with heat and agitation, etches the surface permanently and leaves a gray haze that cannot be polished out. Wash by hand in warm water, one piece at a time.
Which of these can I actually use at dinner?
William Yeoward is made to be used: its stemware and barware are intended for the table and can be added to by pattern for decades. Lalique's 100 Points line is likewise designed for drinking. Daum, and most of Lalique's sculptural work, belongs on the table as an object.
