When Becky Nunn first sent us these great tutorials, this is the one that made me gasp out loud. Sculpting resin? I’d never thought of that! Here, Becky walks us through the process of creating a custom resin mold using any texture you like, dusting the mold with pearlized mica powder, setting an open-back bezel (from her new summer collection) in place and pouring the resin so it takes the texture of the mold. This technique has lovely, ultra-customizable results, as you can see. Read on for a full tutorial!
Materials you’ll need:
Easy Mold Silicone Putty
A Nunn Design brass metal stamping for texture (or a found object!)
A Nunn Design open back deep bezel pendant
Nunn Design 2-part resin kit
Castin’ Craft resin pigments
A non-stick work surface (Becky uses a business card)
1. Pinch off two equal sized balls of Part A and B of the Easy Mold Silicone Putty. Getting the knack for mixing just the right amount of putty will take some practice. You might mix too much or too little putty the first time. Try your best to guess how much putty you will need in order to have approximately 1/8 inch of putty around the outside edge of your bezel’s rim. You will also want the thickness of the silicone putty to be approximately 1/4 inch.
2. The Easy Mold Silicone Putty has a 3-minute working time before it begins to harden and not take the impression. Knead both part A and part B together until the putty is blended completely and has a uniform color.
3. Roll the fully mixed Easy Mold Silicone Putty into a round ball and flatten slightly. Make sure the putty is smooth and not wrinkled.
4. Press your brass stamping or found object into the silicone putty, but not so far into the putty that you hit the bottom.
5. Quickly remove the brass stamping or found object (you can use a toothpick to help release it) and press in your open back bezel in a position that frames the brass stamping impression. Be sure to double check that your bezel is level in the mold. Let the silicone putty set for 25 minutes. Tip: To prevent your mold from sticking onto your work surface, use a glossy business card or a plastic bag, or a non-stick work surface.
6. After the silicone putty has set for 25 minutes, slightly bend back the edge of the mold to release the putty from the edge of the bezel. Voila, you are ready to move on to the next step!
7. Read the resin instructions for safety concerns. When I work with resin, I always protect my work surface, make sure the room is ventilated, wear gloves and a mask, and have wet wipes handy. To start, place one plastic cup (included in the Nunn Design resin kit) onto your table. For curing purposes, it is important that the resin be an exact 1 to 1 ratio of Part A and Part B. I suggest getting your eyes level with the resin so you can see the lines on the measuring cup. Pour Part A of your resin kit up to the 1/2 oz. mark on your measuring cup. Pour Part B of your resin kit into the same cup until it is filled to the 1 oz. mark.
8. Set a timer for 2 minutes. Using a stir stick from the Nunn Design resin kit, slowly and carefully stir your resin, scraping the sides as you stir. Stir for the full 2 minutes. After 2 minutes, scrape both sides of your stir stick on the edge of your resin filled cup. Set the mixture under a warm lamp for 5 minutes. This helps the air bubbles in the resin rise to the surface and pop.
9. After your resin has been under the lamp for 5 minutes, pour a small amount of the mixed resin into a second measuring cup. Add in a toothpick tip worth of both the Castin’ Craft opaque yellow pigment and the Castin’ Craft opaque blue pigment to create the teal color shown here. You can mix the full 1 fluid ounce measuring cup of resin if you want, but I transfer the resin into smaller cups because it is easier to stir and less messy to move around when it’s less full. Tip: Be sure that the colorant does not equal more than 10% of your resin as having more than 10% could prevent it from curing properly!
10. Place the open back bezel pendant back into its groove in the mold. Using a Q-tip, rub some pearlized mica powder into the crevices of the textured silicone mold.
11. Using your stir stick, drizzle the colorized resin into the bezel. Before the bezel is filled to the flush level of the bezel, take a toothpick and gently move around the resin to see if there are any air bubbles trapped in your mold or along the edge of the bezel. If any air bubbles are within the resin, they will rise to the surface from the agitation. Move the bubbles to the edges to pop, or breathe on them. The hot air from your breath will make the air expand and the bubble will pop.
12. Let your resin cure for at least 24 hours. Once cured, slightly bend back the edges of the silicone mold to release the resin-filled bezel.
13. Experiment with different textures for your mold, and different resin pigments and mica powder colors to create stunning, personalized pieces of your own!
