    Hi Guys

    On Sunday we took a trip to our friends farm in Magalies. Hubby wanted to collect some rocks for the fire pit we are building so I took the opportunity to walk in nature and choose some cool rocks!

    These rocks may or may not be used in my next tank. I still need to test them and boil them (if I can find a pot big enough!) etc etc

    So here's a pic of some of my favourite pieces. I collect quite a lot but these 3 are my favourites!

    Don't look so special like that hey? Well here's the one from the centre of the photo... It is natually tiered and has lots of cool little caves and outcrops!

    And here's what the other side looks like!

    Tell me that's not cool!

    Then here's the other two...

    So what you think? Should I use them with these pieces of spider wood? Picture the spider wood going over and possible through the above rocks.

    Hhhhhmmm doesn't that get the creative juices going!

    Let me know what you think!

    Cher

    P.S. These are the rocks we collected for the fire pit!

    Wow, wow, wow! Beautiful rocks! You're so lucky to have access to a farm where you can get them. Definitely use them with the spider wood, though I'm sure you'll get some comments saying go plain iwagumi :p

    One thing though - don't boil them. If they have any pockets of air or gas in them they could explode. Not very likely, but they seem to be interesting composite rocks of the type that might just have something funny like that going on. Rather just pour the boiling water all over them. It will sterilise them perfectly well.

    "If they have any pockets of air or gas in them they could explode"

    The same can be said if you are going to be using them for a fire-pit.

    Thanks for the advice guys! So glad I don't need to go hunting down a pot for boiling!

    These are from an area that is pure Pilandaba rock. In fact one of the quarries that mines the rocks for nursery's is just down the road.

    The rocks for the fire pit are huge, and range in weight from 20kgs to about 50kgs. We filled the back of a Mazda BT50 full of them - who needs gym!

    I very much doubt they have air pockets in them, so for the fire pit they should be safe.

    My favourite tiered piece above weighs about 8kgs on its own, these rocks are HEAVY!

    Went to Smuts House in Irene a few months ago and came back with 12 kg's of rocks, they look very similar to yours. Can't help myself when it get's to rocks doesn't matter what size they are. :laughing7: It might be dolomite and quarts but I might be wrong though.

    Lol very true but if they're in a firepit your face will be far away from them (because fire) instead of peering into the pot! Pretty sure some will at least crack in the fire pit, and it won't be a problem!
    Once I saw someone's mantelpiece that was a huge slab of slate and it had cracked in half from the fire - now that WAS a problem :p

    Great looking rocks Kryo, and the wood also looks fantastic.
    I can see where this is going :thumb:.....looking foward

    Great rocks.. I would put them in the fire, a good burn would kill anything nasty..

    Nice when rocks are found locally.

    Some fine veins of quartz on some of the rocks but no dolomite. I'm a crystal freak so I know my rocks! :p

    Ha-ha funny one Wade! The spider wood pieces actually came from one huge piece that I managed to untangle without breaking. It will be fun aquascaping the new tank. I have been collecting stuff for a few months now, so I can really play around... BTW the new ETA is 2 weeks! :BangHead:

    nice Cher! :) those rocks are amaze balls.

    I spoke to my old Geology lecturer to find out where best to get rocks and she suggested magalies as one of them :) she said in the cape too, there are some nice basalts.

    those look like sedimentary rocks.

    Yeah I think these are more Quartzite, Chert and shale (sediment rocks). The farm is too far away from the Dolomite fault in Magalies which is closer to Harties.

    One of the bigger rocks broke while we were throwing them out of the bakkie onto each other and the inside looks very Quartzite and Chert.

    I didn't even study! I'm no pro thats for sure, but I love rocks and crystals and do research on them a while ago. Here's a link on Magalies http://www.magaliesberg.co.za/mountain2.html.

    My only concern is the other minerals that may be in the rocks, but I did research on that and the worst is iron deposits! Do I care about iron nope! Free plant fert!

    I've used hematite with no ill effect. It did start to oxidise but very very very slowly though.

    Hematite does have some interesting features!
