Hi all, I’m new to this hobby and wanted to encase a few family heirlooms in larger, rectangular molds (say something the size of a thick paperback book) for display on a desk/bookshelf. I’d of course do a few trial runs with similarly sized objects to make sure I got it right. But I am having trouble finding a variety of larger, rectangular mold sizes. Does someone have a source that might have these? Otherwise, is there a person/company that could make some larger molds for me? Thanks!

Hi Grant,

I don’t have a source for large rectangular molds. Have you considered trying to make your own?

Katherine,

I have not. Is it difficult? Are there any good online resources you are aware of that could be useful? Thanks.

Hi Grant,

We have several basic mold making articles here: https://resinobsession.com/category/molds-mold-making

What you are going to want to do is find a book or other item to use as your mold. You will then need a mold box to put the book in. Once secure, you will need to pour the molding material around your book. The Composimold is what I recommend since you are a beginner. You can find it in our store here:

Follow the directions, then use a clear casting epoxy resin to create your items. We also have several in our store:

I realize you will likely have more questions. I’m here to help.

HI, I too am hoping to make my own mold.. Not to sure where to start with this particular item. I have a very large metal clock, around 30 inches. If you turn it over it is hollow and you could easily just pour in plaster or resin to get what I’m looking for, but that would be too heavy, so what would I ‘line’ it with to get a thinner shell. I mean, do I paint on rubber latex and build it up slowly? Any ideas?? THankyou!

Hi Lesley, there are brush on silicone products to help you get a mold, but you will need to brush it on the other side of your clock. That will help you make a mirror image of the clock.

Does that make sense? If not, I can help you with a diagram.
