1960s Cenedese vaseline (uranium) glass bowl

Vaseline glass is glass with uranium dioxide in it that glows fluorescent green under UV black light.  There's not a lot of uranium freely available today, and most of what is available is, frankly, ugly.  Not so this modernist piece from the 1960s.  At 13 inches long it's a substantial piece of art glass.  It's unsigned but was auctioned alongside an almost identical non-vaseline piece which was signed 'Cenedese'. 

This looks good in normal light but to display vaseline glass properly, you also need a UV black light.  We currently have a big Cenedese vaseline vase on a windowsill in our bathroom.  The bathroom has two lights.  One light is a normal incandescent bulb, the other is UV.  The kids get a thrill out of taking a bath with just just the UV light on and the vase glowing. 

Health and safety issues -  http://1st.glassman.com/vaselineglass.html - "One of the most significant aspects of uranium glass is that it is radioactive and does give a positive reading on a geiger counter. This may cause some concern as to its safety with regard to health but I am now able to report that in June 2003 I assisted the UK's National Radiological Protection Board (NRPB) in a study of uranium bearing glass. During this study, technical representatives of the NRPB visited my home and conducted extensive tests on a very wide variety of uranium bearing glass from many manufacturers and time periods. They confirmed that the radiation levels detected were low and quite safe with normal use. The full results of the NRPB study will be published in the near future and at that time I will be providing a link to the publication.

ADDITIONAL SAFETY NOTE: The grinding or abrasive polishing of vaseline glass cannot be classed as 'Normal Use' as the dust and residue produced by these actions can be toxic if inhaled or ingested and therefore should be avoided."
