>I am looking for the recipe for this fixative.  I have:
>600 mL 80% ETOH
>300 mL 37% formol and CaCO3
>Does anyone know what the concentration of CaCO3 is?

we use 20 g of CaCO3 and 10g MgCO3 per litre and adjust the pH to 7,2 with
NaOH. Shake the solution once a week and store it at room temperature.
