Temperable enamelled glass

A temperable lacquered substrate made of glass or lacquered glass-ceramic coated, over the entirety or some of at least one of its faces, with an opaque coating layer, wherein said layer, applied directly to the substrate, is a mineral paint based on an aqueous alkaline silicate solution comprising between 10 and 55% by weight sodium silicate, potassium silicate and/or lithium silicate, mineral fillers and at least one pigment, the lightness of the layer being such that, measured in reflection, the L* component is higher than or equal to 20, and such that the color difference between the substrate coated with said layer before tempering and the substrate coated with said layer after tempering is such that the parameter ΔE*, defined by ΔE*=√{square root over ((ΔL*)2+(Δa*)2+(Δb*)2)}{square root over ((ΔL*)2+(Δa*)2+(Δb*)2)}{square root over ((ΔL*)2+(Δa*)2+(Δb*)2)}, is lower than or equal to 5.0, ΔL*, Δa* and Δb* representing the variations in the L*, a* and b* color coordinates measured on the coated substrate before and after tempering.
