Here are some pieces made with this enamel "Grey speckled PACO":
To create this "Gris moucheté PACO" glaze my starting point was my Peau d'abricot glaze. I liked the speckled character of this glaze. So I carried out a series of tests using my Peau d'abricot glaze as a base, to which I added various oxides. The test with the addition of cobalt oxides caught my attention.

Sample n°2 retained, I thus keep this concentration in cobalt oxides.
I then proceed to a test on a larger room to observe the result:
The result is very satisfactory, we observe the formation of a bluish gray with an ochre speckle.
I decided to do a thickness test using this recipe(link to build a small tool to measure the thickness of the enamel) :
