after i watched NilRed's Cellulose in Schweizer's reagent (tetraamminediaquacopper dihydroxide, [Cu(NH3)4(H2O)2](OH)2 https://en.wikipedia.org/wiki/Schweizer%27s_reagent )i got googling.down in the rabbit hole i found that you can dissolve Cellulose in NaOH (10g/100ml)/Urea (12g/100ml) under 5C .i did that, it was awesome.it is simple yet non toxic way of dissolving cellulose other than toxic copper or very toxic CS2. hope you enjoy. be aware of basic solution follow proper safety guidelines.
