Here are 3 examples I currently have in process which hopefully will all make it through two firings to the finished stage.
The one in the middle has 3 colours of slip decoration- one being a slip made of natural clay. These colours will change significantly through the firing process.
The one on the right I heavily trimmed and fluted as it had spare weight after throwing and shaping but I am pleased with the result.
The one on the left also has slip which has been sponged on and some scratched lines to (hopefully) enhance the slip pattern. The clay is an iron bearing clay which may not be optimal for this type of decoration- we will find out!
