How to Make a Beautiful Eco Resin Turtle – Step-by-Step Tutorial

Hi everyone! Today I’m excited to share how I created this shimmering eco resin turtle. It’s a fun, layered project that looks far more complicated than it actually is. The secret? Pre-colouring the mold with mica powder and doing multiple pours with different colours.

What You’ll Need:

• Eco Resin (powder + liquid hardener or pre-mixed eco resin kit)
• Silicone turtle mold
• Mica powder in your chosen colours (I used greens and golds)
• Mixing cups and stir sticks
• Gloves and a protected workspace
• Optional: heat gun or torch to remove bubbles

Step-by-Step Process:

1. Prepare the Mold
   Start by dusting the inside of your silicone mold with mica powder. I focused on the shell area first using several shades of green and gold mica to create that beautiful iridescent look. Then I added lighter green mica to the flippers and head sections. This dry-brush technique gives the final piece those glowing highlights without mixing colour into the entire batch of resin.
2. First Pour – The Shell/Body
   Mix a small batch of eco resin according to the instructions. I tinted this first pour a dark grey. (enough to fill the shell of the turtle) Carefully pour it into the shell portion of the mold, making sure it fills all the detailed sections (the hexagons and sunburst patterns look amazing when the light hits them). Let this layer set up slightly but not fully cure.
3. Second Pour – Flippers & Head
   Mix another small batch and tint it pink. Pour this into the flippers and head areas. Because the mica was already in the mold, the pink and grey layers pick up beautiful colour shifts and metallic sheen as they cure.
4. Curing
   Let the piece cure fully (follow your resin’s recommended time – usually 24–48 hours). Once cured, gently flex the silicone mold and pop out your turtle. It's Eco Resin, I removed from the mold after an hour. 
5. Finishing Touches
   Trim any flash lines if needed and give it a light polish if you want extra shine.

The ResultThis little turtle came out with a gorgeous metallic green-to-gold shell and soft pinkish flippers — all thanks to the pre-coloured mica technique. It’s now one of my favourite pieces! 

Eco resin is a great sustainable option for these kinds of projects because it’s often plant-based or low-VOC. Just be sure to work in a well-ventilated area and follow all safety instructions.
