Mark and Frances' waxed salt prints have no collodion. The wet plate collodion glass negative is where the collodion is involved, not on the actual print. But a waxed salt print has a different look than the sheen of an albumen print. Wax can be applied to almost any print from a platinum/palladium to an inkjet and it is as simple as it sounds and that is applying it to the surface. An albumen print on the other hand is albumenized before it is sensitized in silver nitrate which gives it a different look than a salt print that has been waxed.
