Copper Hematoxylin

Ingredient Amount Function
Hematoxylin 10 g Dye
Cupric sulphate 2.5 g Mordant
Potassium aluminum sulphate 15 g Mordant
Distilled water 100 mL Solvent

 

Compounding procedure
Place the dry powders in a mortar and grind together.
Add sufficient water to make a paste.
Leave for 48 hours, then add the remaining water.
Leave for a further 12 hours, and filter.

Method

  1. Bring sections to water with xylene and ethanol.
  2. Place into the staining solution for an appropriate time.
  3. Rinse with water.
  4. Differentiate if necessary
  5. Wash well with water.
  6. Counterstain if wished.
  7. Dehydrate with ethanol, clear with xylene and mount with a resinous medium.

Expected results

Notes

  1. The staining time should be determined by trial.
  2. The original method called for 15 grams of "extract of logwood". Gray comments that this has about 70% dye content, so I have specified 10 grams dye.
