I think I might have melt cast my ETN by complete accident! I wanted to give it a very late wash with a hot sodium bicarbonate solution and while it
was not boiling, it was kinda steaming. After heating the solution I transferred it to my 2 liter beaker and then waited a minute before adding my ETN
supply...
and after giving it a stir... the stuff became a blob at the bottom and then kinda stuck there.
I wanted to give it a sodium bicarbonate wash because I never did that before and I thought 'better late than never' to make sure all acid is done and
gone forever (even though I recrystalized this stuff TWICE).
Now I am scared... very scared. melt-cast etn is much more sensitive and I don't want to end up with another 'life after detonation' story. I must
proceed with utmost caution.
edit: OK the big disk at the bottom came out without issue, but it is still solid... I am really scared guys...

I don't think melt cast ETN is more sensitive than powdered ETN. It is more sensitive WHILE you have it heated/molten, but once cooled, it is not.
Probably less so, in fact, than when crystalline.

Cast ETN processing........This process was tryied 10x

That was still a lot of ETN and it was large solid puck. breaking it up and grinding it would require some force. I am not taking that risk. But if it
is actually less sensitive then... cool! I might piecemeal melt-cast my ETN this way in the future.
Yeah I saw your video and downloaded it a long time ago. it had a LOT more ETN than that and it wouldn't be as easy to break it up without some force,
so I didn't want to do it. But maybe next time.
At any rate, I remember that there is no reason not to recrystalize it... so I got some acetone and melt it all in there.

ManyInterests.....Oh yes... hockey puck dissolved in acetone....Always is possible pour 5 grams on warm plate and evaporate acetone. And create thin
layer for small experiments....

I think you're overreacting a bit. You can just dissolve in a solvent and crash it out the ETN to bring it back to a powder, it's rather fragile so I
don't think very carefully crushing it poses too much risk.
Another option is to remelt it in hot water while strongly stirring on a stir plate, this breaks it up into tiny globs which harden as the water cools
yielding a dense and coarse powder. This actually works to neutralize crude ETN if you use a hot bicarb solution, I believe a similar process is used
for processing crude TNT.
I don't know how necessarily safe it is but it can be done remotely.and I've done it numerous times without issue.

It's OK. I recrystalized it. It's fine. I also found that it did need a recrystalization. I remember when I did it last time I thoguht there was some
undissolved ETN. But it turned out to be impurities. I filtered them out this time. So I got some very clean and super pure ETN now.
