Ok here are some pictures of a few colored pontils. I decided to go for unembossed bottles probably blown at Baltimore area Glass Houses.

First picture is of a pure green shouldered umbrella ink. This mold shows up quite regulary in Baltimore privies and comes in most of the normal baltimore colors though I have yet to see one in a sapphire blue.
This is of a very large snuff in a light yellow olive. This one was blown in a dip mold with beveled corners to form the body. I've dug many examples of this mold around Baltimore all broken except this example. They are very early circa 1810ish.
This is a pair of quart sizes porters blown in a 3 part mold These come in an array of colors in cluding the pure green and deep copper puce seen here. Other colors I know of are a pale apple green a deep cherry puce and a yellow topaz.
This is a pair of pint sized porters one in a brite yellow green blown in a 3 part mold circa 1845-50 and the other is an open pontiled dip molded example in a plae apple green color circa 1835-45. Both of these molds can be found in many exciting colors ranging from aqua to grape puce.
I would have to think long and hard about tumbling some of those bottles if I dug them. Probably would leave them alone if they looked as good as those.
Chris -
How scarce are those porters - I'm assuming that certain colors are much harder to find than others, but are there some that you all find often? If it's not way out of my price range, I'd love to find one at the Baltimore show.
