Spend some time searching for and collecting texture, in your house, flat, garden, yard or whilst on your daily walk if you can get outside. Almost anything can be used to make texture!
Let your slabs or work firm up slightly before impressing texture, otherwise things will get stuck and it's difficult to work neatly; test and see what works for you.
You can find information on using oxides and glaze with texture lower down.
Below are photos of oxides and glaze with texture, below that is a really short video on application.
You can find a list of the glazes we have available here www.makenorth.org/forum/painting-glazes
