Glazed and Confused? How to Mix a Color Blend and Interpret the Results

In today’s video, I am sharing a clip (and a recipe) from John Britt’s best-selling video Understanding Glazes. In this (much-condensed) clip, John shares his simple system for mixing up a color blend and tells us what to make of the results. Have a look and then mix up your own color blend and see what you get. – Jennifer Harnetty, editor.

  • was the water content 50% of the dry glaze mix and if so were the colorants added actually twice as much as they appeared?

    Robin, I would assume that when he says 100g, he means 100g of the dry materials, and when mixed up to his preferred thickness comes to that mark. That looks about right with what he’s got there.

    Hi John, been working with this cone 6 glaze. it works very will with additions of commercial stains. For instance I made a nice green adding 1% mason stain 6209.

    I am not clear on what 5×20 means in this context. Can someone explain this notation?

  • Rick L.

    Robin… I believe that is just the name John has given this particular glaze… reason being, if you look at the recipe you will notice there are 5 ingredients and if you look at the quantities of each of these 5 ingredients you can see that they are all calculated at 20 (%). Hence 5 x 20! A simple recipe of equal percentages for 5 ingredients.

    Oooops! My previous post was actually directed toward answering Kelly Miller…. not you Robin.

  • Kelly M.

    Thanks, Rick! Information assimilated ;^)

  • Shelly S.

    Is this a clear glaze without colorants? Good for a liner glaze or over underglazes?
