Title: Portieux Hand Match Holder
Post by: NevB on September 08, 2024, 02:04:58 PM

There are a few of these online usually described as eggcups or toothpick holders. It is actually shown in the 1907 catalogue, although it may be earlier, as a 3944 "porte-allumette" or match holder. It is 8.5cm. tall with a Portieux mark on the base and is well moulded.

It does show a hint of a glow under a 395nm. UV light so it may contain uranium, however it glows much better under 365nm. UV so more likely indicating a manganese content.

Nice. It is uranium: the opacifier dims the glow a bit and seems to give the glass a hint of pearlescence. I have this http://lustrousstone.co.uk/cpg/displayimage.php?pid=1270

Thanks Christine, I think it contains uranium and manganese.
