Pigment Maintenance

I am beginning the task of mulling and bottling each dry pigment. As I mentioned earlier, this method has become favorite, at least for now.



More Penzeys bottles are soon to be ordered and a new order of pigments was recently placed with Kremer:

• Phthalo Green dark - 20g jar
• Phthalo Blue - 20g jar
• Phthalo Blue reddish - 20g jar
• Irgazine® Orange DPP RA - 20g jar
• Irgazine® Red DPP BO - 20g jar
• Irgazine® Ruby DPP-TR - 20g jar
• Permanent Yellow medium - 20g jar
• Dioxazine Violet - 20g jar
• Alizarine Crimson dark - 20g jar
• Verona Green, very fine - 50g
• Titanium White Rutile - 100g

All these pigments carry an "AP" rating from The Art & Creative Materials Institute (ACMI). Here's the AP rating defined:

"The new AP (Approved Product) Seal, with or without Performance Certification, identifies art materials that are safe and that are certified in a toxicological evaluation by a medical expert to contain no materials in sufficient quantities to be toxic or injurious to humans, including children, or to cause acute or chronic health problems. This seal is currently replacing the previous non-toxic seals: CP (Certified Product), AP (Approved Product), and HL Health Label (Non-Toxic) over a 10-year phase-in period. Such products are certified by ACMI to be labeled in accordance with the chronic hazard labeling standard, ASTM D 4236, and the U. S. Labeling of Hazardous Art Materials Act (LHAMA). Additionally, products bearing the AP Seal with Performance Certification or the CP Seal are certified to meet specific requirements of material, workmanship, working qualities, and color developed by ACMI and others through recognized standards organizations, such as the American National Standards Institute (ANSI) and the American Society for Testing and Materials (ASTM). Some products cannot attain this performance certification because no quality standard currently exists for certain types of products."
