be matte across almost the entire range of current densities. No brightness should be seen, except at very low current densities. If a matte hull cell is obtained, proceed to step C5. If not, repeat steps C1 and C3.
C5. Once the solution has been properly carbon treated, remake the bath according to the make-up section of this data sheet.
In most cases, it is simpler and cheaper to regularly decant a portion of the solution rather than carbon treating to keep contaminants and by-products at a
