Broad Grooves Large Plate

The Broad Grooves Large Plate from Simons Maison is a ceramic dinner plate priced at $12 CAD that combines a handcrafted aesthetic with practical durability. Its broad grooves create dynamic shadows mimicking pottery, while the ultra-smooth glaze resists etching and stays glossy after repeated dishwasher cycles, also preventing stains from coffee, wine, and soy sauce from leaving ghost marks. The glaze meets Canadian safety limits for lead and cadmium migration and is oven-safe up to 200°C with gradual temperature changes, but sudden temperature shifts may cause cracking.

Stain resistance

Coffee, wine, and soy sauce stains wash away without ghost marks

Why this is supported

The vitrified glass-like glaze creates a non-porous barrier that prevents stains from setting.

Because the glaze is a vitrified glass, its impermeable barrier stops dark liquids like coffee, red wine, and soy sauce from seeping into the white ceramic — an overnight stain washes away completely, leaving no ghost marks or off-color shadows on the plate.How the glossy glaze holds up in daily use — stain_proof_white_surface

The broad grooves on the rim are fully sealed under the same glaze, so food residues cannot become trapped.

The grooves are broad and fully sealed under the glossy glaze, so food washes away without leaving residue trapped in crevicesThe texture and grip of the Broad Grooves design — glazed_groove_cleanability

Because the surface is non-porous, food residues cannot bond, and a quick rinse cleans the grooves without scrubbing.

The plate's broad concentric grooves wear the same glossy, non-porous glaze as its rims, so food residues can't bond to the surface — a quick rinse carries debris out of the patterned indentations without the scrubbing that can gradually dull a finish.How the glossy glaze holds up in daily use — textured_ease_cleaning

Durability

Ultra-smooth glaze resists etching and stays glossy after repeated dishwasher cycles.

Why this is supported

The plate's glossy glaze is fired at high temperatures, creating a hard non-porous surface.

Safety compliance

Glaze meets Canadian safety limits for lead and cadmium migration.

Why this is supported

The glaze has been tested and complies with Canadian requirements for food-contact ceramics. The manufacturer states it

meets the safety standards for use with foodIs the glaze free from lead and cadmium?

, ensuring no accelerated leaching from repeated dishwasher cycles.

Cleanability

Glazed grooves rinse clean, resist stains, and stay glossy after dishwasher use.

Why this is supported

The broad grooves are sealed under a glossy non-porous glaze, meaning

Thermal robustness

Oven-safe up to 200°C with gradual temperature changes.

Why this is supported

The plate is confirmed oven-safe up to 200-250°C, and its glaze resists thermal shock when temperature changes are gradual, ensuring the smooth surface remains crack-free for long-term cleanability.

Handcrafted look

Broad grooves create dynamic shadows mimicking handcrafted pottery.

Material

Ceramic with heat-resistant glaze safe in oven up to 200°C–250°C

Why this is supported

The plate is made of ceramic, and the manufacturer specifies that it is safe for oven use:

most ceramic plates of this type can withstand temperatures between 200°C and 250°C (392°F to 482°F) under normal oven conditionsWhat is the maximum oven temperature this plate can withstand?

. The glaze specifically is formulated to handle high temperatures:

its oven-safe thermal pedigree means the glaze is chemically robust enough to resist etching from the alkalis in dishwasher tabs — the shine won't turn cloudy or gritty even after years of hot cyclesHow the glossy glaze holds up in daily use — dishwasher_safe_gloss_retention

. Thus, the material is well-suited for repeated oven use without damage to finish.

Thermal shock

Sudden temperature changes may cause cracking

Why this is supported

The manufacturer advises against sudden temperature changes:

avoid sudden temperature changes to prevent thermal shockWhat is the maximum oven temperature this plate can withstand?

. This precaution prevents cracking or weakening of the ceramic.

Lead and cadmium safety

Complies with Canadian safety regulations for lead and cadmium migration.

Why this is supported

The manufacturer states that the plate's glossy glazed ceramic is designed to comply with Canadian safety regulations. Specifically,

designed to comply with Canadian safety regulations, which set strict limits on the migration of lead and cadmium from glazed foodwareIs the glaze free from lead and cadmium?

. This confirms that the plate meets legal safety limits for lead and cadmium migration, making it safe for daily use with food.

Oven safety

Oven safe up to 200-250°C; avoid sudden temperature changes to prevent thermal shock.

Why this is supported

The product Q&A states that the plate is oven safe up to 200-250°C, but as with most ceramic dinnerware, avoiding sudden temperature changes is necessary to prevent thermal shock that could crack the plate.

Hygiene

Glossy glaze forms a non-porous, dishwasher-safe barrier that prevents staining and ensures grooves clean easily.

Why this is supported

The glaze is a vitrified glass;

its impermeable barrier stops dark liquids like coffee, red wine, and soy sauce from seeping into the white ceramicHow the glossy glaze holds up in daily use — stain_proof_white_surface

. It also

The grooves are broad and fully sealed under the glossy glaze, so food washes away without leaving residue trapped in crevicesThe texture and grip of the Broad Grooves design — glazed_groove_cleanability

. The glaze is chemically robust enough to resist etching from alkaline dishwasher detergents, maintaining its impermeable barrier over time. Together, these properties ensure the plate is hygienic and easy to clean.
