The appearance characteristics of glass jars with lids mainly include their shape, size, material and decoration.
Shape and size
The green glass jars with lids in the Sui Dynasty are usually oblate, with a bulging belly, a narrow neck at the mouth of the bottle, and an oblate lid. The mouth and lid of the vessel have traces of grinding, and the bottom is round. This design makes the jar visually beautiful and practical.
Material
The green glass jars with lids in the Sui Dynasty are made of high-lead glass, and the bottle lid and the mouth of the vessel are polished. This kind of glass is called "lead-barium glass", which has high transparency and easy ductility, but is relatively fragile and easy to break when suddenly cooled or heated.
Decoration
The wall of the green glass jars in the Sui Dynasty is extremely thin, transparent green, crystal clear, and beautifully shaped. In addition, the wall contains some small bubbles, which adds to its unique beauty.
