Quick answer
To use a glass lid on your Kuhn Rikon cookware, measure your pot diameter, choose the matching COVER STAR size, place it centered, and avoid sudden temperature changes to prevent breakage.
Why use a glass lid instead of the original metal lid?
A glass lid lets you monitor cooking without lifting the lid, which keeps heat and moisture inside. This is especially useful for simmering, steaming, or reducing sauces where you want to check doneness without losing steam. The trade-off is that glass is more fragile than metal; you need to handle it with care and avoid thermal shock.
Choosing the right COVER STAR size
Kuhn Rikon offers COVER STAR glass lids in 22 cm, 26 cm, and 28 cm diameters. Measure the rim of your pot or pan – not the base – and pick the lid that matches exactly. A lid that is too small will not seal, and one that is too large may wobble or let steam escape. The 22 cm lid fits small saucepans, the 26 cm works for medium pots, and the 28 cm covers larger pans and stockpots.
Step-by-step: Using a COVER STAR glass lid
- 1. Measure your pot rim: Use a ruler or measuring tape across the top rim of your pot. Do not measure the base or the outer edge of the handle. Write down the diameter in centimeters. A common mistake is measuring the base instead of the rim. Always measure the rim where the lid will rest.
- 2. Select the matching COVER STAR size: Choose the lid that matches your pot's rim diameter exactly: 22 cm, 26 cm, or 28 cm. If your pot is 24 cm, the 26 cm lid may still work if it sits on the rim without wobbling, but a tight seal is best. Using a lid that is one size larger can work for some pots, but check that the lid sits evenly and does not rock.
- 3. Place the lid centered on the pot: Set the glass lid gently on the pot so the metal rim sits evenly on the pot rim. The lid should not touch the food inside. For pots with a pouring rim, align the lid's steam vent (if present) away from the handle. If the lid is off-center, steam will escape and heat distribution will be uneven. Adjust until it feels balanced.
- 4. Avoid thermal shock: Never put a hot glass lid directly onto a cold surface or into cold water. Let the lid cool on a trivet or wooden board. Similarly, do not place a cold lid onto a hot pot – let it come to room temperature first. Thermal shock can crack the glass. Always allow gradual temperature changes.
- 5. Clean and store properly: Wash the glass lid by hand with mild detergent and a soft sponge. Avoid abrasive cleaners or scouring pads that can scratch the glass. Store the lid in a dry place, preferably on a lid holder or between pots to avoid chipping. Dishwasher heat and harsh detergents can damage the glass or metal rim over time. Hand washing extends the lid's life.
