Oxide testing

Using my first folding pots as test pieces I experimented with the different oxides in the ceramics workshop. As oxides are natural elements, they produce more organic and natural colours in the glazing and decorating process, primarily making browns, greens, yellows, blacks and blues. Currently I'm aiming to create a sense of decay and decomposition, so focused on using all the colours apart from blue in my tests, thus excluding any cobalt elements.


Over my oxide tile tests I'm going to stripe a thin layer of transparent glaze over the top to see how this changes the colours. I'm expecting it to make some of them more vibrant (like the green chrome oxide) and others more dispersed (such as the silicon carbide). I want to explore if spraying a thin layer over the top would work in sealing them in but not altering their appearance too much.

I plan to trial my favourite glazes over these pots, so far this includes a celadon red, rutile blue, matt white and crackle matt white (pictured below). I will stripe these across the painted oxide pot to see how the different oxides react to the various glazes. Over the dry brushed pot I will also stripe a variety of glazes to see how the combination of oxides impacts the glazes.
