<body class='hmmessage'><div dir='ltr'>Pat touches briefly on the fine particulate nature of dry pigments in general:<br><BR>> But as I noted, Chrome yellow is lead based, in very fine particles. <br>> There's a reason scenic shops stopped using this stuff, and it's not <br>> just that it was a mess - it's pretty toxic to be around, and certainly <br>> to inhale. I shudder to think of how much I used to inhale when working <br>> without respirators or even masks (enough that blowing one's nose could <br>> be a colorful experience for days after).<br>> Pat Kight<br>> <a href="mailto:kightp@peak.org">kightp@peak.org</a><br><BR>But lets be honest: a proper fitting respirator is the PPE of choice while handling dry pigments. Even while mixing. Until its saturated your PPE is required. What's the old saying when baking? "Add dry ingredients to wet... never wet to dry"?<BR> <BR>That being said, I'm not even "Of Certain Age" category and even I have used these pigments. My preference: seal it in a plastic container and get in touch with hazardous material handling folks in your organization/town. There are easier to use methods available that are less toxic. <BR> <BR>Scott Henkels<BR>TD, University Theatre<BR>University of Oklahoma<BR> </div></body>
