Colour modification of poplar wood by steaming for brown colour

Abstract

The colour change of poplar was evaluated after exposure to a wide range of steaming parameters (90–110 °C, 1–20 days) for getting brown colour for indoor applications. The generated brown colour was homogeneous throughout the whole cross section. The colour saturation can be doubled by steaming. Steaming increased both redness and yellowness values and reduced the lightness. The initial redness value was multiplied 4.5 times.
