Minimal Form, Masterful Fire – Handcrafted Porcelain Cups by Kinshou Kiln

Product Description

Behind the deep gloss and smooth texture of the Metal Color Rock Cup lies a story of extraordinary craftsmanship. Each cup is hand-finished using a technique known as luster spraying—a refined method requiring immense skill and years of mastery. A craftsman delicately coats the surface with a fine spray gun, creating a radiant metallic effect that dances with light and adds dimension to the color.

Available in four rich tones—Topaz Red, Galena Silver, Emerald Green, and Corune Blue—each piece feels both modern and timeless. The subtle horizontal texture on the surface provides a refined grip and a sense of movement, while the interior remains smooth and matte to accentuate contrast and elevate the sensory experience.

Its size is generous yet balanced—holding up to 350cc (11.83 oz), perfect for sipping whiskey, savoring iced drinks, or enjoying your favorite cold brew. With a natural coating that extends to the bottom, the cup is scratch-resistant, protecting both the vessel and the surfaces it rests upon.

Packaged in a sturdy, premium rigid box, it’s ideal for gifting, collecting, or treating yourself to a daily dose of beauty and functionality.

FAQs

All you need to know about Japanese Pottery.

What types of traditional pottery are made in Japan?

Japan is home to several renowned pottery styles, including Mino ware (Gifu), Bizen ware (Okayama), Arita and Imari ware (Saga), Shigaraki ware (Shiga), and Mashiko ware (Tochigi). Each region has its own distinct materials, glazes, and firing techniques that reflect local history and aesthetics. Toki City in Gifu Prefecture is particularly renowned as the heart of Mino ware (Minoyaki)—the most widely produced pottery style in Japan.

What materials are used in artisan Japanese pottery?

Most artisan pottery in Japan is made from locally sourced clay, often mixed and refined by hand. Natural minerals and ash are used in glazes, and many pieces are wood-fired or fired in traditional climbing kilns (noborigama), producing unique surface textures and natural variations.

Are artisan Japanese pottery pieces safe for food use?

Yes. Authentic artisan pottery is made with food-safe, lead-free glazes and is carefully fired at high temperatures to ensure durability and safety. However, it's important to follow care instructions, especially for unglazed or porous ceramics.

What makes Japanese pottery different from Western ceramics?

Japanese pottery often emphasizes wabi-sabi—the beauty of imperfection—resulting in organic shapes, subtle asymmetry, and natural glazes. Unlike Western ceramics, which may prioritize uniformity, Japanese pieces often celebrate the individuality of each item, reflecting the artist's hand and the firing process.

How should I care for artisan-made Japanese pottery?

Hand-wash pottery with mild soap and avoid extreme temperature changes (like placing hot items into cold water). Some unglazed pieces may absorb moisture, so allow them to fully dry before storing. Avoid microwaves or dishwashers unless the piece is specifically labeled as safe for such use.

Do I need to season Minoyaki cups before using them?

For most Minoyaki cups, especially if they are fully glazed, seasoning is not required. However, if the cup has an unglazed interior or base, or a slightly porous finish, a simple seasoning process—known as medome—can help prevent stains, odor absorption, and hairline cracks over time.

To season a Minoyaki cup:
1. Rinse the cup gently with water (no soap).
2. Fill a bowl or pot with warm water and add a small spoonful of cooked rice or flour.
3. Submerge the cup and let it soak for 30–60 minutes.
4. Rinse again and let it air-dry completely.

This step helps fill microscopic pores in the ceramic, sealing the surface naturally and extending the life of your handcrafted piece. Always follow any care instructions provided by the maker.
