The second, a Christmas tree. I used the same yellow and red and added green to it. In ceramics, we have glazes that we call chrome tin pinks. It's an odd combination of chemicals because who would think that chrome green would ever make pink? Glazes are not pigments, and with the magic of heat and cooling, chrome and tin, when mixed with other ingredients, will give you a range of hues from pink to magenta and plum. This is the stuff I love about clay. It's where the magic is. It keeps each kiln load feeling like Christmas morning and the feeling of the season in my heart year-round. Back to the tree ornament. The yellow is a commercial glaze, but I'm pretty sure it has tin in it. Whenever I put a green glaze next to it, it reacts. You can see the yellow near the green, blushing pink in this butterfly tile. In the tree ornament, the glaze has gone mottled, giving it an antique look. It's my favorite one of the year.
