Oils intended for use on the table which deposit "stearine" in winter must be freed from such solid fats.
Most olive oils are naturally non-congealing oils, whereas the Tunisian and Algerian olive oils deposit so much "stearine" that they must be "demargarinated."
At low temperatures solid portions - usually termed "stearine" - separate out from many oils; in the case of cotton-seed oil the separation takes place at 12° C. These solid portions can be filtered off, and thus are obtained the commercial "demargarinated oils" or "winter oils."
Other industries include sugar refineries, soap, oil, glass, iron, dye and chemical works; distilleries, breweries, tanneries; tobacco and snuff factories; shipbuilding and the manufacture of machinery and stearine candles.
Other branches of industry include carpet-weaving at Deventer, the distillation of brandy, gin and liqueurs at Schiedam, Rotterdam and Amsterdam, and beer-brewing in most of the principal towns; shoe-making and leather-tanning in the Langstraat district of North Brabant; paper-making at Apeldoorn, on the Zaan, and in Limburg; the manufacture of earthenware and faience at Maastricht, the Hague and Delft, as well as at Utrecht, Purmerend and Makkum; clay pipes and stearine candles at Gouda; margarine at Osch; chocolate at Weesp and on the Zaan; mat-plaiting and broom-making at Genemuiden and Blokzyl; diamondcutting and the manufacture of quinine at Amsterdam; and the making of cigars and snuff at Eindhoven, Amsterdam, Utrecht, Kampen, &c. Shipbuilding is of no small importance in Holland, not only in the greater, but also in the smaller towns along the rivers and canals.
