Bush-hammering Score Flaming it gives marble a rustic appearance while eliminating any differences and variations. This effect is obtained using a hammer with pyramidal points, and the end result can range from extremely coarse to very fine, with various intermediate degrees of finish it consists in scoring the surface creating narrow parallel strikes with diamond-coated discs or a wide range of tools with different profiles it consists in a process using oxygen and gas. The high-temperature flame (2500 - 3000°C) is applied on the surfaces to be treated, which undergo thermal shock. This makes them dilate and crack. The surface texture will appear rough and embossed. Since this vitrification process improves resistance to weather and erosion. Flaming is especially recommended for exteriors but requires skilful use only marbles that are resistant to sharp temperature changes. www.margraf.it Landscape & Urban Design 61
