|Sample from the RGB Set.
The Red Green and Blue company in England sells a very nice element collection in several versions. Max Whitby, the director of the company, very kindly donated a complete set to the periodic table table.
Almost all the samples in the set are very, very nice, but this one I have to tease a little bit. No doubt the glass ampule did at one time contain elemental fluorine: You can tell because it ate the glass on its way out. Glass will actually burn in a stream of pure fluorine (video coming soon). So there may be some silicon fluoride lining the inside of the glass, but there is virtually no chance that there is any element fluorine still inside.
To learn more about the set you can visit my page about element collecting for a general description or the company's website which includes many photographs and pricing details. I have two photographs of each sample from the set: One taken by me and one from the company. You can see photographs of all the samples displayed in a periodic table format: my pictures or their pictures. Or you can see both side-by-side with bigger pictures in numerical order.
The picture on the left was taken by me. Here is the company's version (there is some variation between sets, so the pictures sometimes show different variations of the samples):
