Plumes opalescent

The glass of this vase is opalescent (similar to the color of a natural opal) and is built in three layers. Glass does not refract light like gemstones. Gemstones have a crystal lattice, while glass does not. Because glass lacks this property, it is called 'amorphous' (literally: formless). To acquire the properties of a gemstone in glass, Lalique applied the principle of 'casing', building the object from different layers and colour nuances. By blowing transparent and opaque layers of the same glass colour on top of each other, so-called dilations (separations) are created, allowing light to refract through the different layer nuances. Lalique also applied the same technique to other glass colours in order to mimic the colour and properties of gemstones. He was still a jeweler when he began focusing on glass. He applied both his skills as a jeweler and a sculptor to glass designs, hence the high detailled rendering.

Feathers symbolize freedom, victory, and connection to the spiritual, and are often seen as messages from angels or guides. They represent transcending challenges, clarity of thought, communication, and a deep connection to the element of air and the divine. In various cultures, such as Native Americans, feathers hold great spiritual value and represent protection, courage, and wisdom.
