Saumur: The Timeless Allure of Tuffeau Stone – From Ancient Ovens to Cave Dwellings

Posted by Salvatore Cuomo on

ソーミュール：トゥファ石の時を超えた魅力 – 古代の窯から洞窟住居へ

私のソーミュールへの旅は非常に個人的なものでした。私は特に、何年も私を魅了してきた伝説のトゥファ石を学ぶために来ました。伝統的な薪窯の建設者として、この素晴らしい素材を窯のドームに長い間使用してきました。そして、フランスの建築におけるその歴史的な応用を目の当たりにすることは、非常に感動的でした。 Journey to Saumur was deeply personal – I came specifically to study the legendary tuffeau stone that has fascinated me for years. As a builder of traditional wood-fired ovens, I’ve long used this remarkable material in oven domes, and seeing its historical applications in French architecture was profoundly inspiring.

Tuffeau: A Stone Through the Ages: (トゥフォー：時代を貫く石)

Why Ancient Builders Chose Tuffeau for Ovens (古代の職人たちがオーブンにトゥフォーを選んだ理由)

現代の断熱材が存在するはるか昔、私たちの祖先はトゥフォーがオーブン建設に最適な性質を持つことを発見していました：( before modern insulation materials, our ancestors discovered tuffeau’s perfect properties for oven construction: )

  1. 卓越した保温性
    トゥフォーの微細な多孔質構造は、熱エネルギーをスポンジのように吸収し、ゆっくりと放出します。これにより、パンやピザに理想的な均一な調理温度が保たれます。 Heat Retention     – The stone’s microporous structure acts like a sponge for thermal energy, absorbing heat from fires and releasing it slowly. This creates the ideal even cooking temperature for bread and pizza.
  2. 耐熱衝撃性
    急激な温度変化で割れる密な石材とは異なり、トゥフォーの多孔質性は焼成サイクル中に安全に膨張・収縮することを可能にします。 Shock Resistance     – Unlike denser stones that crack under rapid temperature changes, tuffeau’s porosity allows it to expand and contract safely during firing cycles.
  3.  加工の容易さ
    単純な工具で成形できる柔らかさと、数世代にわたって持続する耐久性を兼ね備え、村のパン職人にとって完璧な材料でした。     – Soft enough to be shaped with simple tools yet durable enough to last generations, it was the perfect material for village bakers.
  4. 湿度調整機能
    石材の自然な通気性により結露を防ぎ、伝統的なパン屋で理想的な生地の状態を維持するのに不可欠でした。 Regulation     – The stone’s natural breathability prevents condensation, crucial for maintaining perfect dough conditions in traditional bakeries.

From Ovens to Architecture オーブンから建築へ

オーブンに理想的だったこれらの特性は、建築物にも応用されました： (same properties that made tuffeau ideal for ovens also recommended it for buildings:)

  • 天然の断熱材（冬は暖かく、夏は涼しい） Insulation (kept homes warm in winter, cool in summer)
  • 構造の軽さ（より高く優雅な建造物を可能に） Lightness (allowed taller, more elegant constructions)
  • 美的多様性（複雑な細部まで彫刻可能） Versatility (could be carved into intricate details)

石と共に生きる：トログロダイトの伝統 (Living with Stone: The Troglodyte Tradition)

ソミュールの洞窟住居は、トゥフォーの特性を活用したもう一つの卓越した適応例です：The cave dwellings of Saumur showcase another brilliant adaptation of tuffeau’s properties:

  • 温度安定性（年間を通じて12-14℃を維持）Temperature Stability (constant 12-14°C year-round)
  • 保護機能（侵略者や自然災害から） PROTECTION (from invaders and the elements)
  • 持続可能性（廃棄物ゼロの建設） Sustainability (zero-waste construction)

生き続ける遺産A Living Legacy

現代で私がトゥフォーでピザオーブンを築く時、私はローマ時代まで遡る伝統に参加しています。中世の石工たちを導いたのと同じ原理が、私の仕事にも息づいています： Today, when I build a pizza oven with tuffeau, I’m participating in a tradition that stretches back to Roman times. The same principles that guided medieval masons inform my work:

  1. 素材の知性：石の自然な性質を理解する. Material Intelligence – Understanding the stone’s natural properties
  2. 熱容量の最適化：完璧な熱の流れのための配置 Termal Mass Optimization – Positioning stones for perfect heat flow
  3. 呼吸する設計：湿気を自然に逃がす Breathability Design – Allowing moisture to escape naturally

結論：物語を語る石 Conclusion: Stones That Tell Stories

ソミュールのトゥフォーは単なる材料ではありません——人類の創意工夫の証です。質素なパンオーブンから壮麗なシャトーまで、この黄金の石は数千年にわたり人々の生活を形作ってきました。トゥフォーで建てられたオーブンに火を入れるたび、私はこの材料の魔法を理解した職人たちの系譜と繋がっているのを感じます。 Saumur’s Tuffeau stone is more than just material – it’s a testament to human ingenuity. From the humblest bread oven to majestic châteaux, this golden stone has shaped lives for millennia. Every time I fire up an oven built with tuffeau, I feel connected to generations of craftsmen who understood this material’s magic.

Salvatore Cuomo was born in Naples, Italy, in 1972, son of an Italian father and Japanese mother. Cuomo was first inspired by his father who also was an Italian Chef in Naples. He began at the young age of 11, where he trained himself in the kitchen and traveled frequently between Italy and Japan. He gradually learned how to blend the traditional Italian art of cooking with the Japanese art of perfection. A few years later he traveled to Japan with his father who opened an Italian restaurant in Chiba in 1984. About those early years Salvatore told the press that it wasn't a good starting experience: "I didn’t like Japan at all, so after one year, I went back to Italy and spent 2–3 years studying at a culinary school. When I was 18, I returned to Japan after my father became terminally ill and I have been here ever since."[3] Cuomo said that Italian Cuisine was just starting to get popular in those days. He and his two brothers decided that in order to succeed in the restaurant business in Japan they would have to understand the Japanese food mentality. They spent a couple of years researching the market before opening a new restaurant in Tokyo with what Cuomo calls "Original Neapolitan pizza." Since that time, Cuomo has been credited with catapulting Neapolitan pizza to fame in Japan, and today in all Asia with over 200 restaurant.
