Glass blown and painted.....

[INgenia]

Hi mates¡
Any idea how to do this blown and painted glass? Those kind of spots, more specially....

Hi, do you mean the material, model, scene lighting, or...?

Hand blown, don't understand the painted glass.

Stretched bubble imperfections, variable refraction's. Art glass!

Alike one below (Cycles, will try replicating with Corona) or stronger, more Murano like or something bit subtle, smoked glass (bit darkened - similar to yours above example).

eg. Cycles (older glass study - colored volume)

Hi,
Material.

Oh, i like! Works just as fine as in Cycles, with caustics also :D

So to give glass smoked/colored feel, use appropriate texture for Volume Absorption & Scattering.
Either procedural (noise...) or an image (aquarels/water color style work best).

Here have used random watercolor image from the web for both (abs. & scatter.), had set distance to 10cm. 
eg.

I am not happy with my test.......it is not the effect wanted.....

Oh, you should know that Glass and other 'shinny-glitter' materials (Reflective&Refractive ie: precious stones, metals, gems, crystals, liquids, carpaints..) primarily demand good lighting/environment - it is what gives the aesthetically pleasing value (beauty) to any form/object.
Surface imperfections (bump, dirt, scratches, roughness, film...) just add to that effect making it visually indistinguishable from photo.

Thanks for the help¡
I have taken note
