    Default i want magnetic glass

    im all googled out.

    anyone know about any magnetic glass?

    the problem is that most, if not all, magnetic materials lose their magnetic properties when heated.

    The lost magnetism will come back (more or less) when cooled, but mixing something magnetic into molten glass and then cooling it without cracking would be very difficult, as magnets do not have a similar coe as boro.

    You could probably find a way to modify a glass and mix in some iron with the glass to make it have some magnetic properties, but probably not enough to really be functional as a magnet, i.e. I don't think you could make the residual iron in the glass a powerful enough magnet to support its own weight. Maybe with a strong enough magnet you could attract it...

    Best bet is to use epoxy or electrforming to attach a magnet to the glass...

    yeah!! i just need it to stick to magnets not be magnetic.

    iron filings maybe. iron powder, better.

    dont want to end up with iron oxide so thats a little tricky.

    soft glass or boro 55? more likely to fit without cracking?

    copper traps well cause it just squishes inside the glass glass. iron is soft ish.

    worst case solution, ity bity tiny fleas.

    Man, there's a couple of people on my IG feed that encase neodymium magnets inside their glass and use them to hold dabbers onto pendants. There's another person that uses them for some kind of a dome attachment or something.

    Actually before I eat my words, I don't know for a fact that they're encased, they maybe glued in there. I know you can't see the magnet, but that doesn't necessarily make it encased I suppose.
    Can "nothing" exist?

    i have seen scientific apparatus with magnets sealed inside. the magnet was just dropped in a tube and closed of at the top....not really encased i guess but it worked.

    I was under the impressions that's how the ones I saw were done as well.

    yes, heat will destroy the magnetic properties of many magnets. so high temp magnet would be important,

    yeah it doesnt need to be a magnet at all just ferrous? iron.

    so no one twisted up some iron filings in there? im about to go drill some holes in some magnetic things for shavings.

    alot of sokols recent work on highpriorityglass has magents to hold the dabbers to the pieces. not sure how its done, you could always make a edge of some sort and epoxy a magnet into it..

    Greymatter's correct. High temps will demagnetize anything you encase. That said, you can remagnetize it. You'd need an ungodly strong magnet/electromagnet to do so, but you could do it. Gluing or epoxying a magnet to your piece likely is your best bet.

    +1 Id like to know how everyones incorporating magnets into glass. I see more and more artists doing it daily

    Not saying it's not a good idea, but everyone else is doing it, isn't that the time to come up with something new and unique for yourself?

    I can see why you would say that menty, but i have a specific application in mind Ive wated to do for quite some time that this would allow me to achieve

    May be of relevance: http://www.britannica.com/EBchecked/...magnetic-glass

    Also the wiki for Michael Faraday Claims he developed a few new types of glass one of which was the first substance to be repelled by the poles of a magnet....

    wiki quote: "Faraday succeeded in liquefying several gases, investigated the alloys of steel, and produced several new kinds of glass intended for optical purposes. A specimen of one of these heavy glasses subsequently became historically important; when the glass was placed in a magnetic field Faraday determined the rotation of the plane of polarisation of light. This specimen was also the first substance found to be repelled by the poles of a magnet."

    Cheers

    i bought 2mm steel bearings, and sealed them individually inside 3mm tubing sections. they stick to neo magnets, but even with that slight separaration the hold isnt strong enough for my app.

    totally forgot to do iron filings tests..............................
