A glass-based assembly includes a glass or glass-ceramic substrate comprising a surface. The surface has flaws, such as a population of small cracks extending into the surface, whereby the substrate is weakened relative to ideal strength thereof. The assembly further includes a coating coupled to the substrate and overlaying at least some of the flaws. Ultimate strength of the substrate with the coating coupled thereto is greater than that of the substrate alone, without the coating.

A heating assembly includes an electric heating plate, a primary thermal conductive layer, a first insulating layer covering the primary thermal conductive layer, an auxiliary thermal conductive layer covering the first insulating layer, and a driving power supply. The electric heating plate comprises a glass layer, a transparent conductor layer disposed on the glass layer, and a decorative layer disposed between the glass layer and the transparent conductor layer. The decorative layer defines a light-transmitting window area and a light-impermeable area. The primary thermal conductive layer comprises two electrical connectors, respectively disposed on opposite sides of the transparent conductor layer. The transparent conductor layer has a first line impedance between the electrical connectors. The auxiliary thermal conductive layer has a second line impedance matching the first line impedance. The driving power supply applies a driving voltage to the primary thermal conductive layer and the auxiliary thermal conductive layer in parallel.
