Vanilla is found in a seed (of the vanilla orchid) called a vanilla bean. The flavor is extracted from the bean by soaking it in alcohol. The vanilla bean is solid, the flavoring- vanilla extract, is a liquid.
Vanilla is derived from the pod of a certain variety of orchid, and this pod is called a vanilla bean. To make vanilla you have to soak vanilla beans in vodka to extract the flavor. So no, usable vanilla is never a solid.
liquid
A liquid extracted from the vanilla bean; used as a flavoring.
solid liquid

Solid
Extract in "vanilla extract" is simply the liquid extracted from the insides of a vanilla bean.
it is a gas
The general classes of colloids are sols (solid particles dispersed in a liquid), gels (cross-linked networks of solid particles dispersed in a liquid), and emulsions (liquid droplets dispersed in another liquid).
A gas is not a liquid or a solid.
change of a liquid to a solid
Whether the solid will float or sink in a solid-liquid mixture depends on the relative densities of the solid and the liquid. If the density of the solid is greater than that of the liquid, then the solid will sink. If the density of the solid is less than that of the liquid, then the solid will float.
