When working with harsh chemicals, you must always be careful and know exactly what you are doing to avoid the risk of mild to severe health consequences. The same rule applies when painting liquid emulsion -- a usually silver-based, light-sensitive chemical -- on paper such as to make your own photographic paper for photography purposes. As long as you take a few precautions such as the use of rubber gloves and use the proper utensils to paint on the emulsion, painting liquid emulsion on paper should be easy and safe.

Things you need
- Bottle of liquid emulsion
- Warm water bath
- Medium-sized brush
- Rubber gloves
Soak the container of liquid emulsion in a warm to mildly hot water bath until at least the top accessible portion of the emulsion is liquefied (at 43.3 degrees C). Otherwise, even at room temperature, liquid emulsion is of a gel-like consistency and cannot be spread and used properly.
Don rubber gloves for safety purposes.
Dip the bristles of your brush into the liquid emulsion and paint the piece of paper. If you plan on doing just one coating, first practice on some designated test paper to determine how much emulsion to apply to avoid unevenness and visible brush strokes in the final product (too thin a coating will cause such discrepancies) . Otherwise, a second coating will ensure evenness. Allow this coating to dry or become close to completely dry.
Paint a second coating of liquid emulsion using your brush. This will result in a final, even layer of emulsion on your paper.
Tips and warnings
- Keep your bottle of emulsion in the warm water bath until you're completely done with it. Otherwise, it will turn back to gel before you're done painting.
- If you get liquid emulsion on your skin, wash with soap and warm water immediately. If you develop a severe rash or skin reaction, seek medical advice right away. According to Dr. Aajonus Vonderplanitz, Ph.D., applying and leaving on whipped, raw organic egg to skin that has come into contact with poisonous chemicals can absorb some the poisonous chemicals that have entered the skin. Apply the whipped egg and leave on for 20 to 40 minutes. Then, rinse with a mixture of one part raw apple cider vinegar to eight parts water. Applying coconut oil or olive oil can help soothe chemical-exposed, irritated skin.
- If you get liquid emulsion in your eyes, rinse your eyes thoroughly for at least 15 minutes or until the irritation ceases. Seek medical attention in all cases of eye contamination.
