Many suppliers supply Collodion U.S.P. with a concentration of nitrocellulose that varies from 4 to 10%. This means your collodion formula may contain double the amount of nitrocellulose. This changes the drying, surface characteristics, and the ageing of your collodion. This is one more variable in a process that has so many.
Our Collodion is made in small batches and has 4% nitrocellulose by weight (5.1% by volume). Most of the contemporary formulas were formulated using 4% collodion. This means your collodion formula will work as intended.
Most of the historical formulas contained 1.0% to 2.0% Nitrocellulose by weight. If you use a collodion with 7% nitrocellulose in your formula you could have twice the amount needed.
Too much nitrocellulose gives you a thicker collodion that may result in crepe lines, thick edges and longer fix times.
