WEBThe cellulose acetate peel method is the primary technique for identifying material in coal balls. It is accomplished by etching the surface of a polished coal ball with 5% HCL to dissolve the matrix releasing a part of the cellular structure; 2540 mu m of material is then transferred to a cellulose acetate sheet using acetone.
