Anyway, there are no contra-indications on the use of an excess ammonia, 
because it will leave the coating while drying.
Casein could be dissolved also in other alkalies, e.g. borax or NaOH, but in 
this case their amount has to be carefully weighted. There are some patents 
in this regard, because casein dichromate (very insoluble in acids) was used 
as a resist for the etching of colour TV screens.
