This process can be done to cotton in any form. Thin fabric or paper may be used to make flash paper, though it is difficult not to rip it during nitration. A glass tray may take the place of a beaker to nitrate sheets of cotton more effectively. A demonstration of such a process using cotton fabric is demonstrated below:
The process demonstrated in the video yields lesser quality nitrocellulose than the above written synthesis will yield, so that should be taken into consideration should top quality be desired.
