Paraffin Test

I am a new user and I do not know a lot about writing on Wikipedia. I have just added the requested paragraph about the paraffin test: Before the use of the scanning electron microscope hot paraffin wax was used to take a cast of the suspect’s hand. The cast was then sprayed with a reagent giving a coloration with nitro-compounds from the partially burnt and unburnt propellant particles. This approach, introduced in 1933 by Teodoro Gonzalez of the Mexico City Police Laboratory, is called dermal nitrate or paraffin test, is no longer used in casework. — Preceding unsigned comment added by 79.47.217.116 (talk) 15:40, 11 November 2019 (UTC)

The paraffin test itself may be of interest to many people. Could someone add something here?69.122.62.231 (talk) 16:24, 23 July 2009 (UTC)

In fact, Rubin Carter (and possibly other articles) link here with the text "paraffin test", so we should either add it here or clarify those links (e.g. "paraffin test for gunshot residue"). --Rob* (talk) 16:58, 13 January 2016 (UTC)

This is possibly the worst Wiki article I've seen so far. Looking for the paraffin test leads to GSR. How are the samples extracted for examination these days? No mention of the paraffin test. When was the sample taking invented? Apparently, the paraffin test was developed in 1933 by a Dr. Teodoro Gonzales in either Mexico or Cuba. All of this info should be included. Is Wikipedia taking a nose dive? I see much squabbling about superfluous issues by some of the same actors. My suggestion would be to get on the stick and fix all this crap. It's embarrassing.Longinus876 (talk) 15:15, 19 June 2018 (UTC)

Recent Developments

According to the German version of this entry, gunshot residue ceased to be considered as a valid source of evidence by the FBI in May 2006. Sanddef (talk • contribs) 04:29, 4 January 2010 (UTC)

In the article "The Current Status of GSR Examinations" by Michael Trimpe it is referred on May 1, 2011 that "the FBI Laboratory no longer accepts GSR cases because of a decision that its resources would serve its community, the United States, better when directed toward fighting terrorism".

Missing Link

The "External Link" (1) goes to a non-existent page. Can anyone fix this to direct to the correct page ? Many thanks ! Darkman101 (talk) 00:19, 22 May 2019 (UTC)

CHEM 300 Course Project

The content, images, and references are the areas that needs the most improvement. In regards to the content, I would add in more information in the organic gunshot residue section, and potentially add in a section for chemical tests. I will update the current practice section with a few more recent practices/studies. I will try to improve the results section by focusing more on what GSR is, and separating the other information into its own section. I will add in my own references and do in-text citations for my work. Potentially, I will find more images to add into the stub. — Preceding unsigned comment added by Ciqiy (talk • contribs) 07:19, 16 March 2023 (UTC)
