The Art of Paint Marbling is a comprehensive workshop tutorial course by Rene Eisenbart. Due out 9th March 2021 from Quarto on their Walter Foster imprint, it's 144 pages and will be available in paperback format.
Walter Foster books (familiar to generations of art students) are well made, instructive, and attractively priced. This book seems to be based around a marbling workshop and the instructions and tutorial sections including the techniques are well arranged, well explained, inspirational, and jaw-droppingly beautiful.
The book progresses from an introduction, including tools and supplies selection, some color theory, and beginning techniques, through specific patterns (freeform, combed, and advanced). There are some suggestions for further exploration, but the bulk of the book is given to very specific, well photographed tutorials for marbling paint on paper/fabric. Additional resources include a really useful short photographic troubleshooting guide with causes and how to avoid them in future, resource and suppliers list (aimed at readers in North America, but useful for readers elsewhere), and a glossary, but no index (at least not in the eARC provided for review).
This is a very useful and accessible tutorial guide and I recommend it highly for printmakers, artists, papercrafters, journalers, bookbinders quilters, and allied craftspeople. It would also be appropriate for kids with some adult help. Some supplies might need specialist suppliers. Five stars.
