ALCHEMY & MARBLINGThis book contains 24 original tipped-in marbles with surprising shapes. Some types, like the tiger eyelets, are very old and are to be found on papers from the 19th century, others are new, for example the travelling drop of paint in experiment 3. Of all the marbles recipes are given. Half the experiments have been done in black paint: a prerequisite to do the work. Moreover, this shows the shapes and structures to their best advantage. It is not until the last chapter that colours are shown in surprising gradations. Size: 30 x 16 cm oblong. Way of bounding: Vellum spine and marbled sides. Sold out.
