John, I am assuming that the other four examples of that "uranium-containing" cane, also glow in the same way. Is that the case?
Sue, John's weight is by Paul Ysart, which is why the canes are set level with the surface of the ground.
There are a some other examples of Ysart canes which glow with the uranium-yellow-green colour under longwave uv light. Most that I have seen (less than six!) show the glow in only a clear central area. John's example shows us that the muddy-yellowish" colour within the cane was also made with uranium oxide in the mix.
Some canes in Paul Ysat items and some in Vasart (and later) have the uranium glow. I suspect that the glass with the uranium mix was used in the 1930s rather than newly mixed from 1946 onward (but I don't know that for sure). So, when Ysart Brothers Glass (Vasart) was formed, some of the canes travelled the short distance from Moncriieff's to Vasart (Shore Works), and some stayed with Paul at Moncrieff's.
