Testing new surfaces

I've been testing out some sodium silicate wash on porcelain slip....in an attempt to generate some more textured surfaces. Some of the results are shown below. It's definitely something I want to progress with and especially with bowl forms. For now I'm going to try out a raku glaze and "wipe back" but I'm also keen to try out Obvara firing and also maybe some wood ash. It will have to wait until the weather warms up!
