Seems to be a 1-3 inch layer of this with my coral over large areas. It silicifies similar to the adjacent coral.Locals have called it pet algae. I think on top. Well sought after by artifact makers. That 4 inch chip came off easy. No more than 3/8" thick. Ninja chip. What are those little barrel shaped specks?   This stuff is all fracture free and chips much easier than coral. Have found artifacts made of it. Side view  |

Ya think Fossilman? The death plates are every where and they all have the same stuff you see. I would wonder if they are urchin spines you would see sticks. But they look like tiny urchin bodies... I hear petrified algae. That type of plate is found from Tampa to Valdosta. Most of it has browner color. Or more drab color. But i am starting to look for it and see what color it has. It is common. |

James, its about time you get yourself an electron-microscope or at least something that you can connect to a computer (for our benefit  ). There sure is a whole world of things in your corals. Not just this one, but a lot of others too. |

Not just this one, but a lot of others too. That would do the budget in many times over Kurt. Got a lot of fossil stuff around here. The coral beds are even limited compared to some areas. All very interesting. |

Ben Krasnow build his own scanning electrom microscope. With that scrap yard nearby and your stash of happy goodness you can too. |

Might be (is) out of this boy's league. I did look at a bit of the video and felt intimidated.

I would like to have a 20-40X micro camera. A good one. Mostly to look at fossils and sand.
The micro world is so busy.

What i would like to have is the device/machine that puts a coating of gold on stones. It may have a super vacuum. And probably uses electricity. Seen stones done that way but can't remember what it is called. Do you know what i am talking about? And i want to know what camera you used to take those striking photos. Damn it man. |

electroforming is awesome.
I am 99% of the way there. I have everything but the success! I have electroplated copper onto nickels and quarters but no love on the conductive paint. I need air agitation, I think.

They paint a conductive paint, copper plate the paint. Once copper plated they can do anything they want. Usually they build up a huge layer of copper then heavy gold electroplate that.

I have heard of people painting their rocks and then sending them in to be plated. Is that an expensive machine or can one of us mad scientists build one? |

electroplating is done using a regulated power supply. I have one that allows adjustment for both amps and volts.
The solution is saturated coppper sulfate ($4 a pound at Lowe's sold as 'rootkiller') with a measure of sulfuric acid (sold at Home depot $10 qt for clearing drains) added for the ions. An excess of copper is used on one electrode and the other is the object to be plated. Turn on the air bubbles, then power it up. lather rinse, repeat until you have your parameters set.
I googled for "conductive paint". The other way to to glue powdered copper, let glue dry and plate. That is how they do babies shoes.
Gold plate same thing, different solutions (Rio!), different power and expensive anode.
