Glad you can use it, but don't anyone of you other kids be playing around with melted pipettes and butane torches if you are thinking of trying to isolate half-fractional elements or anything like that! Maybe I should have replied to you directly, Richard........

Use caution when opening attachments or links from unknown senders. . Yes, Mary, you are just like me. I remembered the paper spot test from my days in electronics kindergarten so I tried googling it up and found quite a good bit of information on it. It was called sulfur acetate paper. Here is just one: https://www.canada.ca/en/conservation-institute/services/conservation-preservation-publications/canadian-conservation-institute-notes/test-sulfur-acetate-paper.html -----Original Message----- From: TechNet [mailto:[log in to unmask]] On Behalf Of Mary Davis Sent: Monday, January 28, 2019 1:32 PM To: [log in to unmask] Subject: Re: [TN] Recommendation for Sulfur Spot Tests I can't give you anything but a vague memory. It is my memory that decades ago glass slides with a vapor deposited silver mirror coating were used to test paper packaging materials for the presence of sulfur. Sulfur caused the silver mirror to turn black. Sorry I don't have any more details.

Currently, using the iodine-azide method from the classic Organic Spot Test book by Feigl with limited success. Hoping some else could recommend some other.
