You can carve added detail or merge multiple pieces to create your desired look. If you overfill or git drips, no problem you can take the hobby knife and clean it up. Now take a small piece of the wax with tweezers, while you are holding over the mold heat with the torch dripping the melted wax into your mold. Like if it is a horse you may only want the head, or if it is a cameo mold and you only want the relief portion. Decide how much of the design you want to use. Place the silicone figure mold down in front of you. The scale is entirely up to you and the project you want to do, but I do recommend testing. These silicone molds help keep us from sculpting but you can carve your own wax design and eliminate this step or sculpt and make a silicone master. It works with wax but silicone shapes are better if your not a person who loves playing and testing. So PLEASE look at the pictures, read the instructions and ask questions. My mass of resin ran a temp and melted my wax like a snowman on the beach !! The resin is mixed and poured in my silicone cake pan, then in goes, my wax skull suspended with a paint stick. So I have my skull, cast of wax and ready for my large disk of resin. Going to create a table with a Reverse Intaglio piece in it. I really love large projects so once I got the jewelry figured out it was time for a large piece. my pieces with wax are small jewelry size silicone molds so they don't heat up as much. Resin gets warm or very hot depending on the volume your mold requires. Leaving behind an embossed space resembling Reverse intaglio I used the putty to make a positive it was pressed into the silicone mold so I could then have a flexable shape that could easily be removed from cured resin shape. The 2 yellow pieces that are ahead and a part of the Seahorse is made of Amazing putty silicone. The pink mold is a silicone casting mold it is what is common. I wanted to show the difference between the 2 methods so you can make an informed decision. Wax is more affordable but silicone or composimold are reusable. There are high temp waxes if you don't want to cast in silicone. Similar to the lost wax method in metalworking. I have a few methods, but the one we are doing today is the wax version.
I pulled some photos from Google on Reverse Intaglio jewelry, this really was inspiring and gave me a great sense of the look and the amount of detail that each piece possesses. This Ible will teach how I create intricate pieces without using drills and carving tools.

So if you are interested in how to achieve the look of hand-carved Reverse Intaglio, you’re in the right place. After many tries, finally, I could say I did it. I went into the studio and began thinking about how I could recreate this elegant style but in Epoxy.
Most important was that I wanted to create not only small jewelry items but large-scale pieces. Yes, we can embed things in resin and cast things in resin, but it was this clear and semi-transparent engraved look that I was interested in. However, I didn’t really find works cast in epoxy. What I found was lots of vintage pieces of reverse carvings from around the 1940s created in Lucite. I sought out to find similar works in resin. The Artisans use many tiny carving tools and painstakingly start carving out the details. Reverse Intaglio seals and jewelry like cameos have intricately carved portraits and scenes, mostly created in Quarts, Onyx, shell, and other stone. As an artist I find it truly rewarding to research the history of such unique things. We also use this vacuum to de-air the investment mixture before pouring it over the wax models to reduce boiling over when vacuuming.The Quest for Reverse Intaglio: /inˈtalyō,inˈtälyō/Įngraving has been around for centuries and this form of reverse carving is extraordinary. Jewelry flasks are placed in a vacuum chamber while this mixture is still fluid, where they are boiled at room temperature to remove air bubbles clinging to the models. The dry ingredients are mixed with water and poured into a container or "flask" surrounding the sprued up model, which is either waxed down to a board or attached to a commercially available rubber device which holds the pattern and flask. The investment mold material is made using gypsum plaster (plaster of Paris) as a binder for sand, silica flour, or another refractory aggregate. We use this method for the Sterling silver we cast while we depend upon spin casting for our pewter line. The method of Lost Wax casting we use at The Rams Horn is called "investment" casting. Working from photographs and sketches they create the initial model in green jeweler's wax. To begin the process of creating a new piece James or Beth work out a new design first on the drawing board.
