Hi Jens,

This is going off topic, but I think that, if you put the lodestone on a float (for instance, a piece of cork or wood) then it would float quite easily.

Hi Fearn,

Yes, you are right of course - I should have thought of it, and yes, you are quite right, I was off the topic

I have had an interesting mail from one of our new members, whom I would like to welcome to this forum, Dr. Ann Feuerbach. In the mail she told me to take an interest in Archaeomagnetism. I did not know the word, but I do know, try to go on Google and look for the word. This, I am quite sure will interest many of you, and it gives the whole discussion another angle. Happy surfing.

Archeomagnetism is using old pottery, iron deposits etc. to study the evolution of the Earth's magnetic field.

Thank you Rivkin, I know that you also tried to direct me in that direction - when you mention the cheramics - but I did not understand it at the time - sorry.
None the less - this is a most interesting subject, and I tink that much more forumites should join.
This is not only facinating, it is essential how to find out, how old a thing is - and to prove it. Any collector must be interested to join this discussion!

Another thing which can be related to this subject is, Archaeomagnetism. The first time I heard about it was from Ann Feuerbach, I tried to look for it on Google, and I must say, if you don't know what it is, have a look - it is facinating.

I had a very hard time getting these two pictures of the Mysore dagger.
It took several days just to get them. I used two different types of material to show the effect, one was a powder Iron and very rusty, but it did a better job as it was finer and dispersed better the other, which was Zinc coated Iron filings while not rusty it very course and did not disperse as well.
Regardless the compass will start N and then S and back to N and finally S at the very tip of the 12" blade.

Hi Fearn,
Yesterday I saw that the compasses were made like a fish (hollow I guess) swimming on oil.
