Whole plate Fuming Boxes
I have completed the two very essential iodine and bromine fuming boxes. I will post the finished boxes later but here are a couple of images of the boxes before they recieved a coat of shellack, a lid, and brass hardware. There is a pyrex dish that sits inside the box that actually holds the chemicals. The top lip had to be ground down perfectly flat so it would seal with the ground glass slide. The Pyrex dish sits on a spring base that adds some upward pressure to ensure that no fumes leak out. here is a short video:
I tested the seal of one of the boxes by burning some paper inside and closing the lid. A vaccum is created as the oxygen is used up in the box. The slide was opened to break the seal and closed to see if any smoke or odor escaped. The box did very well and I am pleased with how they work. The metal springs at the bottom will have to be dipped in shellack or painted to keep them from corroding. The iodine and especially the bromine are extremely corrosive. Here is a video of that:
here is the shellacked box with hinges. The tension of the springs can be adjusted by bending them to give the right amount of upward pressure. I may figure out a better spring system but for now this seems to work just fine.
