Good morning Pat, it's still the same as I said on page 4 - Tommy could you fix the photos in this thread? Thanks. The only ones I could fix were the the three in your post on page 1. Everything else is permanently broken at the host - meaning they were deleted off of photobucket and flickr by the user. Cheers  |

Well, Pat , I only had two dogs in this fight photos in this thread, but I fixed them for you. Now we can try to come to a conclusion on what they are/are not, lol.
You were probably most interested in resurrecting the photos that Frank (3rdrockfromthefun) posted. Thought maybe I could track him down and see if maybe he still had the photos? He hasn't been active over there in more than three years. They had at sometime been deleted from his Flickr account. Not something that can be fixed, like the PB hostage situation. Once something gets deleted from the photo hosting site, it is pretty much gone.
Fixed on page 4, at this link: forum.rocktumblinghobby.com/post/751148/thread

I'm glad this thread was raised from the dead.
I think I might have accidently added a few pieces of opaque black glass to a barrel of obsidian. <red faced>
Is there any way I can identify the glass to sort it back out?

Is there any way I can identify the glass to sort it back out? Generally speaking, black manufactured glass is going to be more opaque and blacker than the obsidian. Hold up a thin edge up to the light. Black obsidian will usually have some translucence and a brownish-gray or brownish-golden color when backlit. No translucence or some other color (bluish or greenish) would make me suspicious, as would color and appearance when backlit that doesn't match your other black obsidian. Chemically, it is an easy job to differentiate between glass and obsidian, but that requires expensive equipment. Comparing with known obsidian from a given area is about the best effort most can do. Color, even in black, is the easiest to spot. Odd inclusions can also help to differentiate obsidian from slag. |

Thanks, @rocks2dust .
I've already used the "backlighting" method on thinner pieces. The problem is with the thicker rounder chunks.
I guess it doesn't really matter as long as I'm not trying to sell any of the questionable stuff as one or the other.
It just pisses me off that I was so careless...

I have a bunch of stuff that I wish I had labeled. I thought- Oh, I'll remember..... yeah, right! |

It wasn't really a case of not labeling them. More a case of not looking at my notebook.
I dumped two tumbler barrels together into the same dishpan to clean and sort.
Only after I'd finished sorting did I look at my notes and see that one barrel had a mix of colored glass and obsidian, while the other was all glass with a special note that some of it was black.
