Burnout or Devore' project

Today I made Devore' or otherwise known as burnout. This seemingly harmless paste burns away the cellulose fibres (cotton, rayon, linen) leaving all other fibres intact (wool, silk, and various synthetic fibres). I have mixed this solution form scratch using the following recipe:
59g Aluminium sulphate

100g powdered meyprogum
900g hot water
