I zoomed in on your 4th Pic
I wouldn't say this is 100% ground up like sand
Its not the fine grain we get here either
And its definitely not cooked, the bits i circled are defo shards of smashed up rock
Just like the S+ i got from USA once and a few times here, half powder like sand and half shard/chunks from smashed up rock/crystal
You can cook it, itll make it easier to rack up and less harsh on the nose, not sure if you know how but heres a quick fool proof guide.
You just put it in a CLEAN frying pan and add a very small amount of water, enough so its all swimming in a small puddle, then cook it on a verrry low heat, untill all the water is gone and the puddle/solution has solidify/stopped moving, then once it stoos moving turn all music etc off and listen carefully and wait until it stops hissing, take it off heat then dab the bottom of the pan with a wet cloth to stop it cooking any more and burning. Then scrape it out with a credit card. If you've never done it before make sure you are sober and haven't done a line first lol.
If its the same as what i had, it cooks up lovely. Do it with a small amount first, 0.5g or 1g, because if there is a cut, it can burn and ruin the whole lot.
