Platinum Boat: Cut from Foil and Bent over a Brass Former (Blair, 1888)
A small trough of platinum foil that carries a sample into a combustion tube. Andrew Blair (1888): "This boat is made by cutting a piece of platinum-foil in the shape shown in Fig. 65, and bending it up over a brass former into the shape shown in Fig. 64."
His pattern is 3.5 long, 1.3 wide at one end and 1.07 at the other, with tabs at each end; the figure does not mark the units. Foil thickness and the former are not given.

Blair opens out the sides to slide in a moist carbonaceous residue, bends them back into shape, dries the boat and contents at 100 °C, and pushes it into the porcelain or platinum tube to burn off the carbon.
