How to Calculate Paper Stock Consistency

Dry the filter paper in the drying oven for one hour and then record the weight.
Obtain a sample of the pulp slurry. Shake the sample well. If it is expected that the consistency will be 1 percent or less, pour 500 milliliters from the sample container into the graduated cylinder. If it is expected that the consistency will be between 1 and 4 percent, pour 250 milliliters from the sample container into the graduated cylinder.
Place the weighed filter paper into the Buchner funnel and wet with distilled water. Apply suction to the funnel. Pour the pulp slurry sample through the filter paper and allow all water to drain from the resulting pad.
Remove the filter paper from the Buchner funnel, taking care to retain all pulp fibers. Place the filter paper in the drying oven and dry until a constant weight is obtained. Weigh the sample, and determine the weight of pulp fibers by subtracting the weight of the filter paper from the total sample weight.
Calculate the consistency using the formula Consistency (in percent) equals the fiber weight (in grams) divided by the sample volume used (in milliliters) times 100.

How to Thicken a Chicken Stock

Pour the chicken stock into a saucepan and heat it on the stove until simmering. The amount of stock will vary according to the recipe or desired use.
Measure one tablespoon of cornstarch and pour it into a bowl with one tablespoon of cold water.
Mix the cornstarch or water with a fork, spoon or whisk until it dissolves completely into a soft paste.
Stir the mixture slowly into the saucepan of chicken stock and cook over medium heat until the desired consistency is reached.



Heat the desired amount of chicken stock in an appropriately sized saucepan until it reaches a simmering boil.
Measure 1/4 cup of cold water and pour it into a bowl. Add two tablespoons of flour.
Mix the flour and cold water until it dissolves completely into a smooth, even paste.
Add the flour mixture a little at a time until the stock reaches the desired consistency.
