# @colineapp/liquid-glass > Liquid Glass for the web: the rim refraction, light and motion of iOS 27's glass on any rounded element, with React bindings and tabs whose thumb lifts into a lens. MIT. Version 0.1.0. Install: `npm install @colineapp/liquid-glass`. npm: https://www.npmjs.com/package/@colineapp/liquid-glass. Source: https://upstream.codes/coline/liquid-glass. Playground: https://liquid-glass.coline.space. ### materialize(timing?) - Type: `(timing?: { duration?, easing?, delay?, scale? }) => Promise` - Group: The glass handle Grows the glass from clear to its tone, for surfaces that appear. Fade the surface's contents, never the surface: opacity below 1 hides the glass. For a surface that zooms open, scale its contents and pass the same `scale`; the glass grows by its inset instead. ```ts await glass.materialize({ duration: 240, scale: 0.96 }); ```
