From the left:

The orange glaze recently posted by Steve Irvine- dipped
The orange suggested by Mel - Rhodes 32 with 1% Iron and 3% Rutile - not =

brown in electric too sprayed
McKenzie Tenmoku over native yellow slip to give more orange when it =
breaks dipped
Two more Reitz Green which breaks blue over white slip and black over =
stoneware sprayed and dipped
And last - Nuka - which is so hard to get right I'm about to dump it =
