FULGURITE
I heard of fulgurite many years ago, but had only ever seen it in photographs. Then one day I was browsing through eBay when I saw these.
10 pieces of fulgurite from Algeria.
Now they have joined my collection!
Fulgurite is also known as lightning stone.
It is formed when lightning strikes sand and fuses it into glass tubes, which are smooth on the inside but rough and granular on the outside. These tubes can be forked, and some can be several meters in length. More information can be found here.
My specimens are small - the longest measures only about 4cm.
If you look closely you can see the tubes.
More F words (no, not those words!) can be found through the ABC page.
Have FUN!

Fascinating! I'd never heard of it before. Interestingly is the fact that the longest piece of it was Found in Florida, which just happens to be considered the lightening capitol of the United States. Thanks for 'something new' learned today!
I have read about them, but never seen them. I read recently that lots of them have been found in Sahara, proving that this once had a much wetter climate.
New word alert! Thank you for letting me know the offical name for "lightening glass." I have heard of it but have never seen an acutal example. Neat!
I'd never seen/heard of these .. how fascinating and pretty they are ... excellent F ..
I came to say fascinating, but I see that someone beat me to it. Never heard of them, but it is quite logical that lightning could do this.
Fascinating is right!
Thank you. I had never heard of this.
I just love ABC Wednesday. I learn so much!

How my father would have loved your posts! He collected specimens of many minerals.
Thank you for informing me about this one. Very educational!
I have never heard of Fulgurite.I aways like to learn new things. You specimens are very interesting.
Those are so cool. I'm going to have to research more about them. Thanks for focus on on these. I love rocks and minerals and fossils.
Fascinating!
Fascinating. I learned something new today. Thanks.
I had an uncle that collected rocks. He had some of that.
One more thing to learn! :o)
Thank you for your sweet words of support, my friend, much appreciated, you know!
Kisses with love from the two of us.
I've learn something new today!fascinating.
Wow, that's wonderful, isn't it? To have a permanent reminder of lightning, formed into stone! It reminds me of obsidian, another volcanic glass - I always feel a sense of awe when I handle it. Pumice, too. I have several examples of that, from New Zealand.
word and concept are new; the things you can buy on eBay, and the places you can buy them from!
Fulgurite - something I never recall seeing before.
It never ceases to amaze me what nature creates!
