2011 forum posts | Coating after exposure to the ammonia fumes seems durable, but is only for decoration so not really tested. I grew up with all sorts of chemicals, most could be bought easily, ether, sulpher, sod. chlorate and nitrate, carbide, etc. etc. Also access to fog detonators, found a Webley pistol with a box of ammo. once, maybe lucky they were all badly corroded. |
