"In Belgium the Roman Renaissance was introduced about the same time as in France: but an unmistakable distinction is visible between the two styles. The buildings in Belgium have a certain stamp by which they essentially differ from those of France; in fact, the whole style might be designated as modern Belgian. The peculiarity of the treatment lies mainly in a predilection for that Renaissance which is called the Roccoco style in conjunction with heavy and often very [skillfully] managed; but still the details are for the most part heavier and more robust than those that belong to the best Renaissance style. [This image] shows this peculiarity, but it is somewhat less marked than in many other instances."

This furnace is used to purify a gold concentrate. The gold concentrates, if non-pyritic, are treated in grinding pans in the bottom of which mercury is placed. The amalgam (mercury alloy), after squeezing out the excess mercury, is heated in the retort, to distil (separate) off the rest and leave the gold, which is then melted and cast into bars of gold bullion of varying fineness.
