银盐感光乳剂配方与制作方法.docInstructions for Making a Simple Silver-Based Photographic Emulsion Suitable for Coating on Glass or Film 制作简单的可涂抹在玻璃或胶片上的银盐感光乳剂
Ingredients: Gelatin, potassium bromide, potassium iodide, and silver nitrate.
成 份 ： 凝 胶 ( 明 胶 )， 溴 化 钾 ， 碘 化 钾 ， 硝 酸 银 Equipment: film or glass plates, metal plates, plastic stirring paddle, cheesecloth, gloves, safelight with light red filter (Kodak 1A or equivalent), 1 liter glass beaker or stainless steel bowl, 4 liter glass beaker or equivalent stainless steel bowl. A mechanical stirrer would be useful, but is not essential. 器具：透明胶片或玻璃板，金属板，塑料搅拌器，粗棉布，手套，安全灯 (红色)，1 升的玻璃大口杯或不锈钢杯， 4 升的玻璃大口杯或等大的不锈 钢杯，以及一个药品搅拌勺也许会派上用场。
Dissolve the gelatin. Dissolve 10 grams of gelatin in 360 ml warm distilled water. 1．溶解凝胶：用 360ml 的温蒸馏水溶解 10 克凝胶。
Dissolve the potassium bromide and potassium iodide. Add 32 grams of potassium bromide and gram potassium iodide to the gelatin solution and stir until dissolved. 2．溶解溴化钾和碘化钾：将 32 克溴化钾和 克碘化钾放入凝胶溶液， 并不断搅动直到溶解。
Heat the solution. Heat the mixture to 130o F (55o C). The solution must be maintained at that temperature. The simplest way to do this is to surround the solution with a water bath.
加热溶液：将上述溶液加热到 55o C,并保持该温度。最简单的办法 是水浴法。
Lights out. Turn out normal lights and work under a light red safelight.
关灯：关掉普通的灯，打开安全灯。
Make a solution of silver nitrate. Wear gloves when working with silver nitrate. Dissolve 40
