Ralph Posted January 21, 2011 Posted January 21, 2011 depends on which aluminium your using what type are you using ?
Zumber Posted January 21, 2011 Author Posted January 21, 2011 depends on which aluminium your using what type are you using ?Bright aluminium......
Ralph Posted January 21, 2011 Posted January 21, 2011 you should add boric acid (2%) as flake aluminium and nitrate react and get very hot and can autoignite I wouldnt go hitting it with a hammer either
Zumber Posted January 21, 2011 Author Posted January 21, 2011 Keep out of a lightning storm, and yer good ok...There will be a static charge in our hands....what cares should be taken while mixing...??friction sensitivity can be avoided using zip lock bag mixing or paper sheet mixing methods....how to avoid static electricity while mixing and handling....??
Ralph Posted January 21, 2011 Posted January 21, 2011 this mix isnt particularly sensitive it should be fine as far as static and friction go especially once its wet and if you were to have a fire from this (which you almost definitely shouldn't) it will just burn and not explode go ahead and make the stars without worrying these stars are very difficult to ignite
NightHawkInLight Posted January 21, 2011 Posted January 21, 2011 Don't mix with plastic bags. That's just asking for trouble when you open it up and the isolated charge of the comp comes into contact with the outside world. That said, this comp isn't particularly sensitive. Friction sensitivity is a very minor concern, just be as careful as you should be with all compositions. Don't rush around your workspace or slam things down on the table for example. Mix it on a sheet of paper or with a screen. As Ralph said, add about 2% boric acid to the water you use to dampen it for stars.
Richtee Posted January 21, 2011 Posted January 21, 2011 . As Ralph said, add about 2% boric acid to the water you use to dampen it for stars.I guess I was a bit cavalier in my reply... sorry. I always used NC to bind similar comps. So I never had the moisture issue.

Mumbles Posted January 22, 2011 Posted January 22, 2011 I only had problems with reactions when a pretty basic ion was in there too like sodium bicarbonate or sodium oxalate. I would probably increase the dextrin a little bit, and bind with thin warm wheat paste. You'll never be able to work the water into the comp and activate the dextrin with just water. alcohol will help some too.
jimbo Posted January 22, 2011 Posted January 22, 2011 yeah I had a batch of win 20 stink my whole house out,it was an awful reaction.
