Learn how to read a measuring jug correctly, avoid parallax errors, and choose the right glass measuring jug for baking and everyday cooking.

Quick answer

To measure liquids accurately with a glass measuring jug, place it on a flat surface, pour to the desired mark, then read the volume at eye level with the jug stationary. For small amounts, use the lowest graduated line that fits your liquid. A clear glass jug like the Duralex Precisio 56 cl makes this easier because the graduations are visible from the side.

Why glass beats plastic for measuring

Glass measuring jugs stay clear over time, so you can see the liquid level and the graduation lines without squinting through scratches. They also resist staining from tomato sauce, turmeric, or food coloring. Unlike plastic, glass does not absorb odors, so your next batch of lemonade won't taste like last night's curry.

The Duralex Precisio 56 cl is made of decorated, non-tempered glass. That means it is not designed for sudden temperature changes like tempered glass, so let it cool before washing if you've used it for hot liquids. It is still a practical choice for everyday recipes because the markings are easy to read and the 56 cl capacity covers most baking and cooking tasks.

Step-by-step: measuring liquids without errors

Follow these steps in order each time you measure. The sequence matters because skipping a step often leads to small errors that add up in baking.

Steps to measure liquids accurately

Place the jug on a level surface: Set the measuring jug on a flat countertop, not on a tilted cutting board or uneven stove. A tilted jug makes the liquid appear higher or lower than it really is. Checkpoint: the jug should not wobble when you press lightly on the rim.
Pour slowly and steadily: Pour your liquid in a slow stream to avoid splashing and to stop exactly at the line. For thick liquids like honey or syrup, pour slowly and let the liquid settle before checking the level. Common mistake: pouring too fast and overshooting the mark, then trying to remove excess liquid, which is messy and inaccurate.
Read at eye level: Crouch or lift the jug so the graduation line is exactly at eye level. Looking down or up creates a parallax error that can change your reading by several milliliters. Checkpoint: the bottom of the meniscus (the curved surface of the liquid) should align with the mark.
Check the meniscus: For water and thin liquids, read the lowest point of the curve. For thick liquids like oil or syrup, the meniscus is less pronounced, so read the flat surface. Common mistake: reading the top of the curve instead of the bottom, which overmeasures by a small but consistent amount.
Use the right graduation for small amounts: If you need 50 ml, use the 50 ml line rather than trying to estimate halfway between 0 and 100 ml. The Duralex Precisio 56 cl has clear graduations for precise small measurements. Checkpoint: for amounts under 100 ml, use the smallest graduated jug you have to reduce reading error.
Clean and dry between uses: Residue from previous ingredients can add volume or affect taste. Wash the jug with warm soapy water and let it air dry, or dry with a clean cloth. Common mistake: using a wet jug for dry ingredients, which makes them stick and throws off measurements.

Product facts

Precisio - Verre doseur / mesureur jaune 56 cl: Precisio - Verre doseur / mesureur jaune 56 cl: Transparent and graduated, decorated non-tempered glass. The clear glass and visible graduations help you read the level accurately, while the 56 cl capacity handles most recipes. Remember it is not tempered, so avoid thermal shock.
Lys - Assiette creuse en verre transparent x6 - 21cm: Lys - Assiette creuse en verre transparent x6 - 21cm: Tempered glass, shock-resistant, thermal shock resistant to 130°C (EN 1183), dishwasher-safe. If you also need bowls for mixing or serving, these deep plates are tempered and can handle temperature changes better than non-tempered glass, but they are not measuring tools.
