The No. 7 Spanish pattern is marbled on black paper with white, metallic gold, and dispersant to push the gold and white into veins.
The story goes that the Spanish pattern was created in the 17th century when a hungover marblers assistant placed a paper on a marbling bath with shaky hands. The pattern traditionally starts with a Turkish base, and the wave-like pattern is made by using a gentle rocking motion when the paper is lain onto the bath.
Spanish is also called Wellen, Griechisch, Ombre Droit, and Espagñol.
