What the glasses and coasters are made of, how big they are, and the few things that will actually spoil one.
The glass
- Soda-lime glass, mouth-blown one piece at a time, then annealed — cooled slowly overnight — so it is not left with stresses that make it brittle.
- The colour is in the glass itself: amber, smoke grey, pale sea green and bottle green. It will not fade, wear or wash off.
- Ribs and facets are formed by blowing into a mould; stems and feet are shaped by hand.
- Lead-free and food-safe.
The coasters
- Travertine (with the Rib Tumbler), blue-grey limestone (Facet Tumbler) and dark green marble (Heavy-Base Tumbler).
- Round, 10 cm across and about 1 cm thick, with a cork disc glued to the underside.
- Travertine and limestone are honed to a smooth matte finish; the marble is polished.
Sizes and capacities
Approximate, measured to the brim. Blown glass varies by a few millimetres from piece to piece.

| Rib Tumbler & Coaster | Amber glass, ribbed | About 9 cm tall, 8 cm across | About 300 ml | Travertine |
| Heavy-Base Tumbler & Coaster | Clear glass, solid green base | About 10 cm tall, 8 cm across | About 320 ml | Dark green marble |
| Rib Goblet | Amber glass, ribbed bowl | About 14 cm tall, bowl 8.5 cm | About 220 ml | — |

Is it a fault?
- Normal: tiny seed bubbles in the glass, a rim that is very slightly uneven, a small mark on the base where the glass was held while it was worked, slight differences in colour depth and height between two of the same piece.
- A fault: a crack, a chip, a sharp edge, or a glass that rocks on a flat surface. Send a photograph and we replace it.
Washing
- Hand wash in warm, not hot, water with a little washing-up liquid. A soft sponge or cloth only.
- Dry straight away with a lint-free cloth to avoid water marks.
- No dishwasher. Repeated hot washes and detergent slowly cloud blown glass and can crack a heavy base.
- No microwave, oven or freezer.
Heat and cold
Glass cracks when one part heats or cools much faster than another. Do not pour boiling water into a cold glass or put ice into a glass straight from hot washing-up water. Warm drinks are fine if the glass is at room temperature first. The Heavy-Base Tumbler is the most sensitive to this, because its thick base changes temperature more slowly than its wall.
The stone coasters
- Wipe with a damp cloth and let them dry before stacking.
- Stone is porous. Red wine, coffee and oil can stain travertine and limestone if left; wipe spills promptly.
- Acids — citrus juice, vinegar, cola — etch marble and dull its polish. Wipe them off at once.
- No bleach or bathroom cleaners. Do not soak the cork.
Storing them
- Store glasses upright, not on their rims: the rim is the thinnest, most easily chipped part.
- Do not stack tumblers inside one another; they can wedge and crack.
- Keep stemmed goblets at the front of a shelf where you can lift them without knocking others.
What actually breaks them
- A sink. Most glasses break against a tap or another glass in a sink of water. Wash them one at a time.
- Temperature shock. Boiling water into a cold glass, or ice into a warm one.
- Twisting the stem. Hold a goblet by the bowl, not the foot, when drying it.
- The dishwasher. Not straight away, but over months.
