How to pour resin for casting in easy steps

If creating fusion/hybrid blanks, start at step 1. If you're only working with resin, start at step 2. 

1. Place the wood in the mold
   Position your wood securely inside the mold. If it's loose or wobbly, use wedges like popsicle sticks to hold it in place.

2. Pick your pigment
   Choose the colour pigment you'd like to use—this is where you can get creative!

3. Prepare your scale
   Have a digital scale ready. You'll need it to accurately measure your resin components.

4. Measure the resin
   All resins come in two parts: Part A and Part B.
   Important: Some resins are mixed by weight, others by volume. Also, the ratio can vary (e.g., 1:1 or 2:1). Always read the instructions on your specific resin to ensure accurate mixing. Working times will also differ.

5. Add your pigment and mix thoroughly
   Once you've measured your resin, mix in your colour. If you're using a powder pigment, be sure there are no clumps. Stir your resin and pigment combination thoroughly. Make sure the colour is fully blended for an even, vibrant result.

6. Pour the resin
   Carefully pour the resin into the mold, covering the wood completely.

7. Use a pressure pot
   Place the mold in a pressure pot to minimize bubbles and ensure a smooth finish. Let the resin sit in the pressure pot for about 4 hours, or as directed by your resin manufacturer.

8. Demold when ready
   Follow the curing time in the instructions. Once it's fully set, remove the casting from the mold—and you’re ready for the next step!
