Mike Robinson has shared some images of his revival of a 19th century French design for half plate fuming boxes. The compact boxes feature a bottom pressure plate similar to a printing out frame back, to keep the iodine dish in contact with the ground glass. Mike explains that since the brass is on the other side of the wood from the iodine it doesn’t suffer from corrosion. The glass tray is flat pieces of glass glued with marine epoxy which is holding up well. The copper runners ensure the ground glass cannot be accidentally withdrawn and the whole design is very compact for the traveling daguerreian.
