One covered a method for treating beeswax so that its melting point was raised from 60 to 100 °C (140 to 212 °F). This occurred after boiling the wax in a solution of sea water and soda three successive times. The resulting harder wax is the same as the Punic wax referred to in ancient Greek writings on encaustic painting.
Most coatings have four basic components. These are the resin, solvent, pigment and additive systems [5] but the resin or binder is the key ingredient. Continuing environmental legislation in many countries along with geopolitics such as oil production are ensuring that chemists are increasingly turning to waterborne technology for paint/coatings and since resins or binders are the most ...
Water-based lacquers are used extensively in wood furniture finishing as well. One drawback of water-based lacquer is that it has a tendency to be highly reactive to other fresh finishes such as quick-dry primer (excluding waterborne lacquer primers), caulking and even some paints that have a paint/primer aspect.
Oven Method: Preheat the oven to 400?F. Cut little crosses in the chestnuts as described before, then place them in a roasting pan and cook uncovered for 20-30 minutes.
Wax emulsions based on beeswax, carnauba wax and paraffin wax are used in creams and ointments. The emergence of soybean waxes with varying properties and melt points has led to the use of vegetable wax emulsions in applications such as paper coatings, paint and ink additives, and even wet sizing for pulp and paper applications.
Place the chestnuts in a holey pan and place the pan over a fire. (This method also works happily over a normal gas stove.) Watch the pan throughout cooking, shaking it every now and then to prevent the chestnuts from burning too much -- you want them to char but not burn to a cinder.
Wrap a piece of bacon around each water chestnut and secure with a toothpick. Place the water chestnuts in a 9-by-13-inch baking dish. Bake until lightly golden and starting to crisp, 20 to 25 ...
Wood finishing is one of the most traditional and still popular uses of shellac mixed with solvents or alcohol. This dissolved shellac liquid, applied to a piece of wood, is an evaporative finish: the alcohol of the shellac mixture evaporates, leaving behind a protective film. [39] Shellac as wood finish is natural and non-toxic in its pure form.
