Also, a pic of the whole bottle & a close-up of the top would help us date the bottle...

YEP. The iron oxide residue has been cleaned away, or was lost due to soil conditions. Has the bottle been tumbled? Sometimes, with a little over zealous cleaning the black, or red, residue is polished off.

I believe graphite is the wrong term though often used. It's usually referred as an iron pontil (IP) or bare iron pontil

I have never sen it written down,but if it's orange rusted I 'll call it Iron. If it is black I'll call it Graphite. The very light hazy appearing type I call Sand . If I'm not sure I'll call them Improved as a cover all. I could be wrong. That's just me.

I think to be most accurate Iron or Improved would be most correct, collectors use other terms to be more descript. Sand pontils were when the Rod was actually dipped in sand to make it easier to remove from the bottle. I thought I read somewhere Iron oxide was also used. Not always a bare Iron Rod. Can anyone help enlighten us?

My understanding is that something needed to be used as a release agent to keep the rod from sticking (permanently) to the bottle. There were several different methods used including iron oxide(this can occur naturally on a bare iron rod), graphite,sand, and glass chips. Iron oxide leaves a reddish or brown residue, graphite leaves a gray or black mark, sand leaves a rough sandpaper like mark, and sand chips are small sharp bits of glass.

These are just my observations from what I've seen and read. Let me know if I have it wrong.

The term we use out west is Improved Pontil. The removal of the tubular, or open, pontil mark via various means was an improvement in the bottle blowing and finishing process.

I don't think that Graphite, Iron or other terms are incorrect, either. Those descriptions have been in use since the beginnings of bottle collecting.

Matt is correct about the different materials used to keep the pontil from sticking. Pontils were also used bare.

An improved pontil is a type of pontil rod that was supposed to make it easer to release the pontil from the bottle. Some had hatch marks some had dimples and so on. Simply put the standard iron pontil is the improved pontil. It was called that becauce it replaced the glass pontil.

Graphite pontil? No such animal. The grey deposit is left by an iron pontil. The gray or black color comes from ferrous iron and the red comes from ferric iron.

Check out the BLM site. Bill Lindsey explains it far better than I can and shows pics to boot.

It's all starting to come back to me now. Thanks Cap. It's been years since I read on the specifics of pontils. Thanks.

By Graphite, I didnt mean to imply that the rod was graphite. I meant that powdered graphite was used as a release agent. Its long been known as a high temperature lubricant. I think I read somewhere it was used in the glass blowing process. Maybe its just a myth, I'll try to do some research.

Hey Matt, Thats not what I meant. The graphite used on the end of a pontil as a release agent will brush off and not leave a residue. It will look like a fine sand pontil. It's still a favorite of glass blowers today.

For those who didn't know, there is no such thing as a graphite pontil rod.

Didn't they whittle them graphite rods down, wrap them in cedar and call them pencils?

Just kidding.
