Researching the Specials Department Experimental Glazes plus a link to the Gallery

It would be best if we could have a clear photo of the base markings and a photo of the resulting glaze.  Head the post with the large single number or letter first if there is one, then the fractions not the shape number so that we can see any similarities at a glance.  As there appears to be a huge variation of how these have been recorded on the base, you will have to use your initiative to title your post.  I am interested to see how many glaze numbers were used and the combinations that resulted and the colours that ensued.
Lots to do so chop chop

A zero before a single large number needs to be used so the computer can put these into the right numerical order.
