The factory ordered a new muffle to fire enamel coatings on its kitchenware line.

工廠訂購了一座新的隔焰窯，用來燒製廚具產品線的琺瑯塗層。

Please confirm the shipping date for the replacement muffle our ceramics studio requested last week.

請確認我們陶藝工作室上週申請的替換隔焰窯的出貨日期。

During the plant tour, the manager explained how the muffle protects glazes from direct flames.

參觀工廠時，經理解釋了隔焰窯如何保護釉料不直接接觸火焰。
