  1. Can I paint oils on top of a drird QOR painting? I want to use QOR as a color trial layer prior to final oil painting.

  2. Hello,
    Thank you very much for this article. You opened my eyes on using synthetic gall on Lanavanguard.
    Your mediums give me great pleasure to use and I like the results.

  3. Good Day/Evening Ms. Cathy.

    Concerning QoR’s Watercolor Medium, I have noticed something very interesting when I added it to my gum arabic-based gouache. In thick applications, it increases the flexibility of the resulting paint layers to the point that it prevents cracking and flaking-off. When prepared as a dilute solution, it enables gouache made with non-granulating pigments (such as phthalo blue) to make granulating washes. With this, I highly recommend using the watercolor medium even for gouache.

    • Hello Clarence,
      Thank you for sharing your creative experiences with QoR Watercolor Medium. It is wonderful to hear how well the Medium increases the flexibility and granulation of your gouache applications!
      Warm Regards,

  4. I am fascinated by your watercolors! I love that they are vegan, but I have reservations about the synthetic part. Are these made from petrochemicals? Are the chemicals used safe to send down the drain? I avoid toxic pigments for that reason. When I use acrylics (which, trust me, I’m conflicted about), I use your crash kit. Should I be doing that with QOR? Also, is paynes grey toxic, dickblick.com seems to think it should have a prop 65 warning? Thanks.

    • Hello Tracey,
      Thank you for your questions! We consulted people in our Health and Safety Department and in our Lab in response to your questions, and we will answer them one by one below. QoR Ivory Black contains PBk9, a pigment created from carbonized cattle bones. Yes the Aquazol and surfactants used in QoR are petrochemical in origin. QoR paints can safely be washed down the drain. We have found that the Crash Kit does not produce satisfactory results with watercolors. QoR Payne’s Gray Payne’s Grey is very safe. Carbon Black, a pigment used in the color, is on the State of California’s list of chemicals “known to cause cancer”. However, that is a catchall, unfortunately, that doesn’t reflect the hazards of this product, nor the fact that the carbon black pigment we use is selected to be ultra-low in PAH content, the contaminants of potential concern in carbon black compounds. In addition, we have all our formulas reviewed by external toxicologist for their safety. You are always welcome to call Golden at 607-847-6154 or (toll free in the USA) 800-959-6543 and ask to speak to our Health and Safety team, they are happy to talk with artists with questions about our products. We hope this is helpful, and we wish you happy painting! Cathy
