mrcasey Posted November 22, 2019 Report Share Posted November 22, 2019 This week, someone donated a number of old glaze pigments to our community studio. Some of the jars in which the pigments come have labels; some don't. The jars with labels have the names of chemical companies and the names of the stains. Some also have dates of manufacture and a few of the elements in the stain. However, none of them have the specific chemical formulae of the active ingredients. Because some of the manufacture dates go back to the late 40's, I'm concerned about use of dangerous ingredients. In particular, I'm concerned about lead, barium, cadmium, and even radioactive material. There are no reds, but there are some pinks, yellows, and oranges. Has anybody used these? There are many more, but I've only take pictures of these. Link to comment Share on other sites More sharing options...

liambesaw Posted November 23, 2019 Report Share Posted November 23, 2019 I'd probably not mess with those, or maybe gift them to a sculptural artist. Link to comment Share on other sites More sharing options...
neilestrick Posted November 23, 2019 Report Share Posted November 23, 2019 Totally scary. Wait for a free toxic materials waste pickup in your area and get rid of them. Link to comment Share on other sites More sharing options...
Mark C. Posted November 23, 2019 Report Share Posted November 23, 2019 Drakenfeld made great colored pencils in the 70s-since 1869 what could go wrong. Many of you young pups where not around back then. Ok I'm in Bali and feeling great-spending most of everyday under the sea. Link to comment Share on other sites More sharing options...
Magnolia Mud Research Posted November 23, 2019 Report Share Posted November 23, 2019 For the stains that have labels with the ID number for the stain and its manufacturer you should be able to trace back to the manufacturer for composition data to guide your decisions. Search the internet for listings of stain compositions. For those without such information, follow Neil's suggestion. LT Link to comment Share on other sites More sharing options...

No way to know what has been contaminated or not in the last sixty years or so even if you find the original compositions and the sheets accurately represent everything in them.
