Surface texture and crystal glaze attempts
I tried pressing the texture on the ceramic surface and used a crystal glaze. I found that the crystal glaze is better suited to craft with more volume and that you have to be careful to control the position of the crystals when glazing, different coloured crystals too close together will not work as well.
I have also tried some glazes suitable for high temperatures which are lighter in colour, especially blue, and are not suitable for painting lines, are suitable for laying down colours on a larger scale and require at least three coats of glaze. The blue looks the darkest before firing, but is the lightest after firing, and all this experience needs to be gained in practice.
