According to Gray it is:-

Water - 100 mL
Sulphuric acid, 5% aqu. - 2 mL
Potassium dichromate 5% aqu. - 2 mL
Chrome alum - 1.5 g
Hematoxylin - 0.5 g

Dissolve the alum and the hematoxylin each in 50 mL water.
Combine the two solutions.
Add the potassium dichromate and sulphuric acid.
Leave for 48 hours to ripen.
