Ferro-fluid from laser printer toner.

[Answerprancer]

I saw a few videos that featured ferro-fluid and its bizarre properties and went researching about how to get hold of the stuff.
I found a few bits of info including a couple that said you can make it by adding vegetable oil to toner powder from - for example - a laser printer cartridge.
I managed to get hold of a discarded toner cartridge and did as instructed (spilling some of the stuff onto my carpet in the process!) but it didn't work.
So my question is this: are there 'ferrous' toners and 'non ferrous' ones ?

Most Toner is just Carbon black (soot) mixed with a binding agent to make it stick to the paper.

A Ferrous toner will be this stuff

I used to work for Xerox research UK so I am familiar with this. Common name Magantite or Black Ferrous Oxide.

BTW.... toner is know to be quite a bad health risk when inhaled, I really wouldn't suggest emptying toner cartridges at home.

Thank for those answers. I've just researched and found a site that sells powdered magnetite, I will probably order some.
