About this book

The Theory and Practice of Enamelling on Iron and Steel by Julius Grunwald, 1909. The enamel sign maker's technical manual — back in print.

Porcelain enamel signs — the gleaming, permanent, weatherproof advertisements that still hang on brick walls a century later — were made by enamelling on iron and steel, and Grunwald's 1909 book is the technical foundation: the theory and the practice, the furnaces, the grounds, the colors, the firing, all of it.

The 208 pages are serious industrial chemistry in service of the sign trade — the science behind the most durable sign ever made. For the enamel sign collector and the student of the sign industry, it explains how those century-old signs were born: why they survived when painted boards faded.

The technical bible of the enamel sign, reproduced complete.

Details: 6×9" paperback, 208 pages, black and white interior, cream paper.

⚠️ Please read before ordering — about print quality

This is a print-on-demand reprint of a scanned historical document. The pages were scanned from an original 1909 printing, and the print quality of your book reflects the condition of that original scan.

What that means in plain terms: you may see faded text, uneven inking, age spots, show-through from the back of pages, and other imperfections that were in the 1909 original or introduced by the scanning process. These are preserved as-is — they are not printing defects, and they are not something we can fix.

We are not responsible for the condition of the original source material. If you want a pristine modern typeset book, this isn't it. If you want the actual 1909 manual with all its character intact, you're in the right place.
