What Customers Ask About Le Creuset Seattle Mug 400ml
Whilst exact time varies depending on room temperature and initial drink temperature, Le Creuset's specialist stoneware typically maintains warmth noticeably longer than standard ceramic mugs—often 15-30 minutes longer for hot drinks. The thicker clay walls and superior heat retention properties mean you can enjoy your coffee or tea at optimal temperature through leisurely mornings rather than rushing before it cools. This matters particularly for those who sip slowly or get distracted during breakfast.
The 400ml capacity suits those who prefer generous servings—it's larger than standard 250-300ml mugs. This size accommodates substantial Americanos, large lattes with milk, generous teas, or hot chocolates without being so oversized it becomes unwieldy. If you typically drink smaller coffees or espresso-based drinks, this might hold more than you need. If you enjoy large, leisurely hot drinks or frequently refill smaller mugs, this capacity provides satisfying servings without multiple trips.
Mug height varies by coffee machine design. The 400ml capacity means this mug is taller than standard mugs, which may not fit under some pod or espresso machines with low spout clearance. Measure the clearance under your machine's spout before purchasing if this is your primary intended use. The mug works perfectly for kettle-poured tea, French press coffee, or larger coffee machines with adequate clearance.
Yes, Le Creuset stoneware is microwave-safe—the 260°C temperature tolerance far exceeds microwave temperatures. You can reheat drinks or warm milk directly in the mug. The stoneware heats evenly without creating hot spots. Always use caution when removing from the microwave, as the handle and body will be hot. Allow the mug to cool slightly before handling or use an oven glove.
Specifications
Care & Use Instructions
Before first use: Remove all labels and packaging. Wash in warm, soapy water, then rinse and dry thoroughly.
For hot drinks: The specialist stoneware retains heat excellently. Pour your coffee, tea, or hot chocolate into the mug and enjoy drinks that stay warm throughout leisurely mornings. The comfortable handle allows secure grip even when the mug body is hot. If desired, pre-warm the mug with hot water before adding your drink to maximise heat retention.
For cold drinks: The stoneware works equally well for cold beverages. For iced drinks, refrigerate the mug beforehand to keep drinks cold longer. The 400ml capacity suits generous servings of iced coffee, cold brew, or chilled beverages.
Microwave use: Safe for reheating drinks or warming milk directly in the mug. Heat in short intervals, stirring between, to ensure even temperature. Always use caution when removing from the microwave—the handle and body will be hot. Allow to cool slightly or use an oven glove when handling.
Daily cleaning: Allow the mug to cool completely before washing. Rinse away coffee or tea residue. For tea stains or coffee oils, wash with warm, soapy water using a soft sponge or cloth. Hand wash and dry, or place in the dishwasher securely. The scratch-resistant glaze releases most residue easily without aggressive scrubbing.
Removing tea or coffee stains: For stubborn tea tannin stains or coffee oils, create a paste of baking soda and water, apply to stained areas, let sit for 10-15 minutes, then scrub gently with a soft brush or sponge. Rinse thoroughly. Alternatively, fill the mug with warm water and add a denture cleaning tablet, let soak overnight, then wash normally. Regular cleaning prevents stain buildup.
Removing spoon marks: If metal spoons leave grey marks on the interior glaze, these are typically metal deposits rather than scratches. Remove them by rubbing gently with a paste of baking soda and water, then rinse. The scratch-resistant glaze itself remains undamaged—the marks are surface deposits that clean away.
Storage: Store the mug clean and dry in cupboards where it won't knock against other items. If stacking multiple mugs, ensure handles nest comfortably without strain. The durable construction means the mug can be stored with other dishes without special precautions, though avoiding unnecessary impacts preserves pristine appearance.
Avoid: Never plunge hot mugs into cold water—this creates thermal shock that may cause cracking. Don't use abrasive scrubbers that might dull the glaze over time. Whilst the mug is oven-safe, there's rarely practical reason to place mugs in ovens—stick to microwave for reheating drinks.

Le Creuset stoneware is exceptionally strong and durable compared to standard ceramics, but it's not unbreakable. The specialist clay construction provides good impact resistance for everyday bumps and knocks. However, dropping from height onto hard surfaces will likely cause chips or breaks. The mug is designed for long-lasting daily use with reasonable care rather than being specifically engineered for high-impact scenarios.
