Im: manufacture of the caramel is carried out at or nearthe ordinary atmospheric pressure in a vessel connectedwith a iendenser or absorber (open at its outlet), where the vaporated substances usually lost, are recovered. The vessel is also provided with a cover, through which the vapours are conducted to the condenser, and which is so 1 ( means of counterweights and water-sealed 1 m - as to rise when the pressure within the vessel becomestoo great.—C.
