Nice work at that site, thanks for posting.
However...
I got to thinkin', wouldn't it look better if the sponged and fragmented colors were inside the bottle, with a grime (glue and cinnamon) on the edges of the outside? That way, you still get the depth of old glass.
As an example, take that first one, the black and red mottled look. You could put a small piece of sea sponge on the end of a straw or a pipe cleaner and speckle that red stuff on the inside walls of the bottle. When it dried, fill the bottle with black and swirl it around, so that the black is under the red.
That should give you the same texture and color scheme, but with the glass between you and the contents.
Smearing a little elmers glue on the outside to fog and haze the glass, as well as dirt around the neck and the lower body, would really create an extraordinary prop.
And, if you wanted bottles to look like earthenware or metal, give them three or four coats of artist's gesso on the outside, then a coat of acrylic craft paint in whatever color you want - glazed brown, tan, metallic copper, aged bronze, etc.
