Spectrum 1540 Matte Blue From  £17.02

This Spectrum glaze does not run a mile when fired. It has quite a stable composition. The glaze is much bluer and a bit speckled- not so even. But it looks really nice. It is definitely towards the blue rather than grey-green as image. The glaze has lot of character and might not suit minimalist objects. I tried it on Scarva Earthstone Professional PF700 Porcelain White Stoneware. This glaze doesn't warp the shape as I have experienced other Spectrum glazes to do. I will use this a lot.
