thanks, i am terrible with safety and am sure to pay for it down the road (I am getting better though after some headaches after working with concrete for a week!) so really appreciate the safety notice!!

Justin is correct in suggesting it would be good to consider the dust toxic, avoid inhalation, and perform a thorough clean up afterwards and yet the info I am finding via websearch (the blurb below is typical) indicates this stuff is not all that horrendous as compared with a bunch of acutely hazardous substances and chemicals. It is in a totally different class from the radium which was used on watch faces once upon a time. Cement also has slightly higher radioactive emission than background, so this stuff is about the same as cement in terms of hazard factor, from what I am reading. Best to be cautious, even so.

Please do keep us posted on the progress of your piece and perhaps post a couple photos showing it in daylight and under UV.

"Vaseline Glass is a particular color of yellow-green glass that is made by adding 2% Uranium Dioxide to the ingredients when the glass formula is made. The addition of the Uranium Dioxide makes the glass color yellow-green. Vaseline Glass is ALWAYS verifiable by using an ultraviolet light (blacklight) on the glass item. When this is done, the glass turns a bright florescent GREEN! Vaseline Glass was primarily made from 1840, up to just before WWII, and then was continued from 1959 to the present. Current manufacturers include: Fenton Glass, Summit Glass, & Mosser Glass. Vaseline Glass is not harmful, as the emissions from the glass are just slightly stronger than normal background radiation that we are all exposed to on a daily basis."
