6 Hoehnel's Reagent
Solution 1: 1 gram of potassium iodide dissolved in 100 cc. of water, and iodine added in excess. Solution 2: 20 cc. of glycerol are mixed with 10 cc. of water. To this cold solution are added 30 cc. of concentrated sulphuric acid. The fibre is first treated with Solution i, the excess of reagent is removed with filter paper, and after one or two minutes Solution 2 is applied. -

8 Schweitzer's Reagent
A solution of ammonia and copper oxide used for many tests. When cotton is placed in this solution the fibres swell and then dissolve. The reagent is of a deep blue colour. The action of this chemical on cotton is utilised in the manufacture of cuprammonium rayon. Cross and Bevan prepared it as follows: - 5 gramms copper sulphate are dissolved in 100 cc. of water. Hydrated copper oxide is precipitated from this solution by adding a slight excess of sodium hydroxide. The precipitate is washed entirely free from alkali, drained, and mixed with a 10 per cent solution of glycerol. The reagent is kept in stoppered bottles and when required for use is washed free from glycerol and dissolved in ammonia water of 20 per cent strength.Dictionary of the English textile terms > Schweitzer's Reagent

10 Loews' Reagent
Ten grams of copper sulphate crystals are dissolved in 100 c.c. of water. To this is added 5 c.c. of glycerol and a solution of sodium hydroxide until the precipitate at first formed is just re-dissolved. -

12 Nickel's Reagent
A solution of hydrazin sulphate in water. -
13 Richardson's Reagent
Twenty five grammes of nickel sulphate crystals are dissolved in 300 cc. of boiling water, and precipitated with a slight excess of a 10 per cent solution of sodium hydroxide. The precipitate is carefully filtered and washed, then rinsed into a 250 cc. flask containing 125 cc. of ammonia (Sp. gr. = 0.88). The whole is then made up to 250 cc. with water.Dictionary of the English textile terms > Richardson's Reagent
