I haven’t even finished all the tests for this glaze, and already I just HAVE to start writing the article.  I just got off the phone with Steve Lampron, the head “glaze guru” at AMACO (I think his actual title is ceramic engineer or something super brainy-sounding, but I like glaze guru).  I had sent him an email asking him some questions about the “beyond the label” uses of the glaze, (because you know me, I like to color outside the lines)  I had wanted to add some colorant to the white pebble, and was debating between adding velvet underglaze (as I have done with the arroyas before) or stain, and then secondly, how much to add?  (One of my earliest tests with the white pebble included blending equal parts by weight of stain and white pebble.  I can tell you definitively THAT is too much.) I never would have thought of using an actual glaze to tint the product.  Steve explained to me that the white pebble is very unique in its properties.  It has an extremely high surface tension, which is what causes it to bead up the way it does, and it’s a delicate balance of refractory materials & softer materials, so trying colorants which have both of these properties make sense.  Thus, after chatting with Steve, I decided to do three separate line blend tests to color the white pebble – 10%, 20% and 30% each mason stain 6226 Dark Leaf Green, velvet V353 Dark Green & Teacher’s Palette 41 Frog Green.  (Teacher’s Palette glaze  was chosen because they use the same frit as the white pebble) Steve and I also wondered what might happen to the glaze when fired to Cone 5, so we tried that too.  I have to say, I was thrilled, excited, and inspired by the results.  White Pebble will definitely find its way into my regular palette of glazes for interesting effects!  What do YOU think of the results?
