The optimal conditions were determined to be: initial pH 3.88, [Fe2+] = 5.01 mM (along with [Fe3+] = 8.0 mM) and [H2O2] = 30 mM in the case of photo-Fenton process operated with UV-C irradiation; and pH 1.9, [Fe2+] = 8.39 mM (along with [Fe3+] = 8.0 mM) and [H2O2] = 30 mM in the case of UV-A light application.
And if the rate was not high last fall, then a light application can be made now.
This, explains Steve Woolf, a professional collector, is where acetone comes in: a light application of the chemical removes the inscription without damaging the photograph.

If the lawn is fed this season, then only a light application, half of what is put down in fall, is sufficient.

In a nice sleight of hand — and a light application of Ruskin's pathetic fallacy — these fish act out, as if on a stage, the story's larger questions: How can a child understand his father's suicide?
Gravlax, cured at the restaurant, achieves a plush, velvety texture that makes the gravlax at other restaurants seem a little coarse, and a light application of horseradish cream gives it understated kick.
