Nungali Posted Tuesday at 10:37 PM like sand ... after a big explosion Fascinating stuff 'mere' sand , depending on where it comes from ; I was out on Francios Peron peninsular - that most western part of Oz With an Aboriginal elder , we where walking along this amazing beach with multi-coloured sand , like a rainbow going down to the shore , I collected some different colors and made lines of then side by side on my palm and showed them to him ; " Look at this !" " Do you know what that is ?" he asked and pointed to the green " Thats emerald ... " and the pale blue " Topaz " the dark red "Ruby " .... and so on . 1 Share this post Link to post Share on other sites
Nungali Posted Tuesday at 10:41 PM I have a big bag of white topaz sand ; it came from very deep underground , got it from an abandoned mine ( supposedly it was going to be used for heat resistant space shuttle tiles ? ) . Its very bright white and sparkly and surprisingly heavier than beach or river sand . 1 Share this post Link to post Share on other sites
zerostao Posted Wednesday at 12:24 AM (edited) I had a galaxy all my own once Spoiler In fact, it was my first car, when I turned 16 A 1968 red two door 2 barrel 390 V8 with fm stereo Galaxy 500 At my final job the song played over the Playlist while we worked. I told a co-worker that a Galaxy 500 was my first car. She said, she thought a Galaxy 500 was a phone. I was like,yeah, an apple used to be a fruit.

old3bob Posted Wednesday at 09:13 PM off topic but I did a little bit of basic sand casting work with molten aluminum, that was neat! Some people do very complex sand casting which is pretty amazing. Share this post Link to post Share on other sites
