Charbonnel Lefranc and Bourgeois engraving bitumen powder 500gr

• Powdered bitumen is used to granulate zinc and copper plates and to prepare etching grounds, especially in the aquatint printing technique.
• It is finely ground and soluble in turpentine and white spirit, which facilitates its application and mixing with other materials.
• To improve the acid resistance of the powdered bitumen, it is mixed with varnish. This can be especially important in the etching process, as acid resistance is crucial to protect the desired areas during the etching process.
• It is important to note that sprayed bitumen is not the same as sprayed resin. Both are products used in etching, but have different characteristics and properties.
• It has a weight of 500 g.
