I am looking for information on Zinc Chloride solution for use on weak Ninhydrin prints. any positive or negative feedback is appreciated. Also looking for a formula for mixing it. I have looked at several different mixtures, but am having a hard time locating particular chemicals.

If you check the Reference Index at www.redwop.com with a keyword search of "zinc", you will get a listing of several articles/papers on the use of zinc compounds for latent prints. Do not limit it to "zinc chloride" because metallic complexes are sometimes expressed in other forms.
