About this book
From the silicone skin of a one-off sculptural piece to the rigid plastic of a mass-produced soap mold, the quality of your final product is determined long before you pour your first batch. The Complete Handbook of Craft Molds is a practical, engineering-centric reference designed for professionals and serious enthusiasts who need to get it right the first time. This book breaks down the physical and chemical properties that define a good mold, translating esoteric data like Shore durometer and heat distortion temperature into actionable selection criteria.
The handbook covers the entire lifecycle of a craft mold. It details material-specific design considerations for resin, concrete, soap, wax, ceramic, and food-grade applications, and provides clear protocols for installation, demolding, cleaning, and long-term storage. It also diagnoses common failures like sticking, tearing, and loss of detail, offering concrete troubleshooting steps and preventative maintenance schedules.
The book concludes with the business of molds. It analyzes the major supplier tiers, from budget importers to premium domestic manufacturers, and explores viable business models, including reselling, consulting, and private-label production. With a thorough glossary and a preview of emerging technologies like 3D-printed mold masters and biodegradable mold materials, this is the only reference a professional maker needs on their workbench.
Reader Reviews

★★★★★Alright, I'll admit this is the most thorough resource I've found on mold specs. The chapters on silicone types and durometer actually helped me pick the right rubber for a tricky concrete project I've been fighting with. My main gripe is that it's a bit too dense for a casual reader like me, and the chapter on business models felt a little out of place. But if you're doing this professionally or at high volume, it's a solid desk reference. I've already used the cleaning protocol section to revive an old mold I thought was dead.

★★★★★I manage a small soap and candle manufacturing line, and this book has paid for itself a dozen times over. I've spent years poring over data sheets from different suppliers, and it's all finally organized in one place. The troubleshooting chapter alone is worth the price - it correctly diagnosed a recurring tearing problem we had with our silicone molds and gave us a fix that saved us from replacing them. I've already handed it to two of my foremen. It's not a hobbyist's guide; it's a proper technical manual, which is exactly what I needed.

★★★★★There's a lot of good information here, and I appreciate that it treats you like a professional. The comparison of heat resistance and the section on storage was really practical. But I felt the tone was a bit dry and academic in places, especially early on. I also wish there were more visual diagrams in the physical book, as some of the concepts are easier to see than to read about. It's a good resource to have, though. I'll probably keep it on my shelf for the tables alone.
