That and the inevitable impurities in the iron used on the end of the pontil rod. You see some odd colors once in a while. I've never been a fan of the theory that some iron pontil marks were painted. I can't see any commercial glasshouse taking the time to paint the bottom of a soda bottle and for what practical reason? It's about as practical as "refired pontils".

I can't see getting all the paint out of the pontil when done. Gray iron colored paint maybe. Never tumbled a iron pontil for fear of messing it up. Not like I find them everyday.

There are plenty of threads posted on this subject on this site. Do a search on tumbling iron pontils and a number of options are discussed. Good luck.

So far, I haven't been able to navigate the website very well. The reason is because I really stink with using computers. Will get better, but it will take time.
I just posted a picture of some of my misc. bottles, it took me over 2 hours to successfully get them posted (finally my wife helped me or I would still be trying to post them.)

Are you accessing the site through Google Chrome or the tapatalk app? I find the Google Chrome easier to use. I logged in using the tatatalk app and was totally lost. I removed tapatalk and only use Google Chrome to access from now on.

What is a refired pontil? I have heard of them, but I don't really know what they are.
I have some nice iron pontiled sodas and would love to clean them up. However, I still don't know what to do about losing the iron on them. O/Ps are easier to tumble.
I don't know about the different colors you sometimes find on the iron pontils. I just accepted them as they were.

Re-fired pontil? Sounds impossible. Could you be talking fire polished?

It could be a fire polished pontil. Heard of both the refired and the fire polished pontil. What is a fire polished pontil?
All of my sodas and mineral water bottles are iron pontiled. I had a few O/P sodas, but sold them.
I had a Nash iron pontiled and wish I had never sold it.
I think I use chrome Google, not sure. I want to find another search engine, mainly becasue I don't care for Google.

They fire polish the with a high temp torch melting the surface. This breaks the surface tension and smoothes it out. It is done during the manufacture of the bottle before the annealing process.
