Vinod Chettur revision from a classic glaze (VC mate 71). Brown yellowish, breaks brown. Satin matte.
I use to fire it at a hot cone 5, with slow cooling cycle: 2 hours from peak temperature to 850°Celcius.
I replaced the Frit 3134 originally in this recipe for Gillespie Borate 9 I don't know if it were due to this or the firing which was
to Cone 6, 20 min hold (no slow cool) that my results were nothing like those pictured in the original recipe (Photo FIG 1). I will attempt the recipe again like for like and see if I get my matte iron yellow! However.........
I did try the base recipe (FIG 2 BASE) on clay body B = Scarva Earthstone Porcelain White and C = Oxidising St Thomas Stoneware
with the following Variations
R7102 + Copper Carbonate 5 (FIG 3)
R7103 + Rutile 15 (FIG 4)
I then achieved some lovely results from layering one colour variation over another (1 short dip for each layer)
(FIG 5) is the R7101 with R7103 over
(FIG 6 ) is the R7102 with R7105 over
(FIG 7 ) is the R7101 with R7102 over
