耐熱ガラス
解説 Definition
膨張係数が低いホウケイ酸ガラスの商標名。熱に強く、温度変化に強いため、調理器具や実験器具として広く使用される特殊なガラスです。
Pyrex is a trademark used for heat-resistant glassware and related kitchen or laboratory products. The name has historically been associated with low-expansion borosilicate glass, although the materials used in products bearing the brand may differ by manufacturer, product line, and market.
覚え方のコツ Memory Tip
Pyrex は本来商標なので通常は大文字で書き、Pyrex baking dish、Pyrex glassware、Pyrex measuring cup のように製品名の前に置きます。耐熱ガラス一般を厳密に指す普通名詞とは限りません。最初期のパイ皿とのつながりを手掛かりに、オーブンや実験室で温度変化に耐えるガラス製品を思い浮かべましょう。
Remember Pyrex as a brand name, normally capitalized, that appears in combinations such as Pyrex baking dish, Pyrex measuring cup, and Pyrex glassware. Picture a clear dish moving into a hot oven or laboratory glassware being heated during an experiment. The brand’s early association with a pie plate provides a practical spelling cue for the beginning of the name. However, do not automatically use Pyrex as the technical name for every kind of heat-resistant glass. It is a trademark, and products sold under the name may use different glass compositions depending on the manufacturer and region.

pyrex の語源・成り立ち Etymology
Pyrexは1915年にCorningが作った商標で、継承語というより英語内の造語。最初の製品がpie plateだったためpie由来とされ、同時にギリシャ語pyr「火」も連想させる。だから耐熱ガラスにふさわしく、関連語としてはpie、連想上ではpyreが挙げられる。
Pyrex was coined as a trademark by Corning and introduced in 1915. It is an English commercial name rather than a word inherited through older stages of the language. Accounts from Corning connect the name with an early pie plate and the company’s established pattern of product names ending in -ex. The spelling may also evoke Greek pyr, “fire,” but that association should be treated as suggestive rather than as a securely documented derivation of the entire name.
