Very cool spear head even if it is glass |

The only thing I can think of is that it may be from copper smelting.

A long time ago I heard that the glass with the white spheres in it was from a Coca-Cola factory that burned down.
I have a piece around here myself.

Wow that’s so weird. I just found a big round chunk of green glass yesterday, but it doesn’t have any of the white stuff on it.

Got any nickel mines close by toiv0 ? White specks and chunks in slag glass is usually a sulfide. Nickel sulfide is used to make figures to be cast in glass without cracking the glass. Not many materials can be cast in glass without cracking it. Chances are if it is white and it did not crack the glass it is a sulfide. sulfide marbles  Nickel sulfide reaps havoc in tempered glass. Causes spontaneous failure.  butterfly fracture in China  butterfly in France  another  |

I have no idea what this article is talking about. I guess we get bombarded with sulfides from space. RocksInNJ ?? "Glass with embedded metal and sulfides (GEMS) are tiny spheroids in cosmic dust particles with bulk compositions that are approximately chondritic. They form the building blocks of anhydrous interplanetary dust particles (IDPs) in general, and cometary IDPs, in particular. Their compositions, mineralogy and petrography appear to have been shaped by exposure to ionizing radiation. Since the exposure occurred prior to the accretion of cometary IDPs, and therefore comets themselves, GEMS are likely either solar nebula or presolar interstellar grains. The properties of GEMS (size, shape, mineralogy) bear a strong resemblance to those of interstellar silicate grains as inferred from astronomical observations.[fn 1]" The plot thickens: "A Chondrule is a round grain found in a chondrite. Chondrules form as molten or partially molten droplets in space before being accreted to their parent asteroids. Because chondrites represent one of the oldest solid materials within the Solar System and are believed to be the building blocks of the planetary system, it follows that an understanding of the formation of chondrules is important to understand the initial development of the planetary system."  I'm tellin ya, RocksInNJ is behind all this. |

Here's a piece of the Coca-Cola slag. The spheroids are formed from radiating fibers of some sort.  |

I have a handful of old green coke glasses and a couple of the old bottles. I wonder if they would melt down to something like that?

Here’s the chunk I found behind the old glass factory next door the other day. /pic5221664.jpg) |

I could only find one reference to that glass, which was an item listed on Ebay. EXTREMELY RARE COCA COLA GLASS SPHEREA rock dealer friend told me that the glass was from a Coca-Cola plant in Texas that burned down in 1950. Apparently all the molten glass ran down into the basement where it was left to cool down. They had such a problem with trespassers taking the glass, that they ended up bulldozing the pit to prevent more theft. A bunch of the glass ended up on the lapidary market for a while. |

Here's a piece of the Coca-Cola slag. The spheroids are formed from radiating fibers of some sort. That looks like a classic sulphide spheroid amygdule. Looks like classic Coca Cola colored glass too. Synthetic opal is another compound that has properties that allow it to be reliably melted into glass. You avatar looks like glass with opal fused into it... |

Looks like sulfide inclusions RocksInNJ. Sweet find. |
