I tried to create a glass material for a vial that I created in Blender. I am just wondering if it is possible to create it in a way that it would mix a color of glass and the object or a fluid that is inside. Here is a screenshot of my current object:
I also put a cube inside to try it out and a plug, but neither color can be seen through.
I think that sort of property is determined by the shader used by your material. In general more information in your post is helpful; for instance, how did you create this material?
There is a nice set of glass shaders in the asset store: Glass Shaders: Ciconia Studios
In particular: fast glass 2-sided gives the effect you are looking for.
Btw the vial looks good 
Hi, maybe you could like this new asset for glass materials, it uses a substance material with limitless possible customization to the glass material you need.
