  2. For the life of me, I am unable to print the article about mediums vs. additives. It keeps bringing me back to your website. This is not a problem I typically have.

    • Hi Trudy, Just under the title of the article on the right, there is a button to push to print the article. This should put it in a format for easy printing. If you are still having trouble, please feel free to email us at [email protected]. Thank you for your interest!

  3. Hi Janet, Thank you for your question and interest in GAC 800. You are correct that the GAC 800 is not available in the UK, but the Color Pouring Medium Gloss should be available and you should see similar results when using this product. Here is the information about the Color Pouring Mediums from the goldenpaints.com website: https://www.goldenpaints.com/technicalinfo/technicalinfo_colorpouring

  4. I have many many powders for painting on China and porcelain but they are old and not labelled so I can’t use them in the kiln. I wondered if I could mix them with a medium and use as acrylic paint? Which medium would I need for that?

    • Hi Janet, It really depends upon what type of powder you would like to add. If it is pure pigment, it may be ok to add in very small amounts to an acrylic medium of your choice, but if a powdered ceramic glaze, we would not recommend adding to acrylic paint. We do not know how it will behave or react, as we have not tested this application. We also do not recommend our paints be used on anything that would be used for food or drink or that should hold water.

  5. Thank you for the very clear explanation. I was previously intimidated by Golden’s variety of mediums but thanks to this article, I feel armed and am excited to experiment with them. Also, if I understand correctly, “wetting agents” are basically flow improvers?

  6. I used the Golden’s extra heavy gloss gel for texture on a gessoed MDF support. I expected it to dry clear. After waiting 3 days it still has a cloudy/yellowish tone. What did I do wrong?

  7. You are such a good resource regarding medium technology. So I need some help. I have a gallon of Golden Gloss medium and have run out of matte medium. Is the any way to add something to make some of my gloss into matte?

    • Hi Jerry, thank you for the nice words! The only medium that could potentially lower the sheen of the Gloss Medium would be the Super Matte Medium. It would not likely not make it matte though, you would get a sheen between depending upon how much is added, somewhere between semi-gloss and satin. It will also change the consistency of the Gloss Medium and make it less syrupy. Testing first would be key to try to get a sheen and consistency you desire.

      • You are the queen of technology and I thank you for your response. Since mediums are the absence of pigment, could a small amount of zinc white provide the “matteness” I want, or would it alter the mediums’ ability to seal a layer of my painting?

        • Hi Jerry, Adding white would only tint the medium white. It would not make the medium less glossy, especially since the Zinc White is a rather glossy color. If you would like to use the Gloss Medium as is, you could always apply a matte varnish at the end to make your painting have a matte appearance. The Gloss Medium (or any acrylic medium) does not really seal anything, but it can make it less absorbent. We have an article about this topic here: https://justpaint.org/how-do-i-seal-it/ We hope this helps!

    • Just started using Golden Crackle Paste. Please provide choices of what to seal it with and when to seal it. My concern is to prevent “chipping”, allow for painting and/or tinting. Can I effectively use gesso, or some medium?

      • Hello Jerry, you could use a thin medium like High Flow Medium or GAC 100 to apply on top that will soak into the crevices and get around the platelets. This would help anchor them to the surface. You could use some Gesso, but if it is too thick, you could dilute it slightly to work it into the crevices, being white it might obscure some of the cracking. Here is our tech sheet on Crackle Paste: https://goldenpaints.com/technicalinfo/technicalinfo_crcklpst Let us know if you have questions [email protected]

  8. Hi Stacy, hope all is well. I need your sage advice. I’ve been experimenting with Golden Crackle and need your advice regarding the best type of undercoat and overcoat. Looking to prevent crackle pieces from dislodging and still allowing color to be added.
