What is the most practical method for producing and storing Schweizer's reagent [Cu(NH3)4(H2O)2](OH)2? Should I follow the

CuCO3+NaOH -> NH3 procedure or the CuSO4+NH3 -> NaOH?

Is it more easy and practical to dry it out or to store it liquid? Will it release ammonia gas both in the crystalline and the aqueous form? What if stored with cellulose dissolved in it already? Will it preserve longer?

Maybe I am thinking of another Reagent but doesn't it decompose when you try and dry it out?
I think it decomposes to Copper hydroxide along with Water and Ammonia vapor.

Yes, that's why I'm asking. Sources on the net say it can be also dried out but I am not convinced of its usefulness at all.

Strange, Personally I would keep it in a sealed glass container as most of my chemicals. But why not experiment? Try both at the same time and see what happens.
