Product Insights
The Grooved Blue Mug by Simons Maison features a hand-applied reactive cobalt glaze that yields one-of-a-kind veining, marbling, and shade shifts, so each mug is unique and no two are identical. While dishwasher safe, the glaze may fade or lose shine over time, making hand washing the preferred method to preserve its finish. Matching pieces are available but sold separately, and due to the reactive glaze, each item has a distinct pattern and color tone, with shade variations between batches — buying multiples at once ensures the best color match.

Deep Research
What makes reactive glaze unique
- Reactive glazes rely on metallic oxides — typically cobalt for deep blues — that interact with other glaze components and the kiln environment to produce mottled, flowing colors; for this midnight-blue mug, the cobalt oxide likely creates unpredictable veining, shade shifts, and subtle crystalline textures that cannot be replicated, which is why no two pieces emerge visually identical even from the same production run.
- Reactive oxides are sensitive to the kiln's oxygen levels during firing, so minor atmosphere shifts between batches alter the final blue tone; some mugs will lean darker navy while others show faint lighter highlights, making individual pieces unpredictable in detail and reinforcing the artisanal nature of the finish.
- Each mug is glazed by hand rather than machine, so subtle differences in brush pressure, glaze pooling, and edge thickness create local variations that the reactive firing amplifies into distinct organic marbling — the mug's exact pattern and color placement are unrepeatable by design.

Q&A
2 answered- Will the reactive glaze maintain its color and finish over time with regular dishwasher use?
- The product is labeled dishwasher safe [product description], so it is designed to withstand regular dishwasher use. However, some sources note that reactive glazes may gradually fade or lose shine over time due to high-pressure jets and strong detergents [1]. To preserve the finish, hand washing with mild detergent is recommended if possible.
- Are there matching dinner plates or bowls available in the same grooved blue design?
- The product listing states that matching pieces are sold separately, indicating that other items in the Grooved Blue collection exist. However, it does not specify which pieces (e.g., dinner plates, bowls) are available. We suggest checking our store or contacting us for the full range.
