Chris Lefteri has some of my favorite books on materials on plastics, wood, ceramics, metals, and many others. I’m not as aware of his books series called Ingredients, but as Ingredients No.4 is released September 24th, it seems his previous ones are FREE to download! How awesome! If Ingredients is anything like his other materials books, be prepared to be floored both visually and with information about each. Download the other 3 here:

– Plastic Ingredients No. 1 (PDF format, 3mb)

–  Ingredients No. 2 (PDF format, 2,9mb)

– Ingredients No. 3 (PDF format, 2,1mb)
