What primary material did Nicolas Appert use to hold food during his thermal sterilization process?

Answer

Thick glass bottles

Nicolas Appert's revolutionary approach to food preservation involved using existing technology adapted for a new purpose. He carefully packed various foodstuffs, including meats, dairy products, and vegetables, into sturdy containers designed for liquids. These containers were thick glass bottles. After packing, the opening of each bottle was secured using corks, which were then sealed over with wax to ensure an airtight closure. The sealed bottles were then submerged in boiling water for specific, calculated durations. The success of his method depended entirely on maintaining this hermetic seal using the glass vessel while simultaneously applying sufficient heat to halt spoilage agents.
