Make designed coconut shell bowls which are suitable for the modern domestic household.
These half coconut shell half epoxy casting bowls are a great way to get started with plastic resin casting for the first time. This project should take roughly 1 hour before casting is ready (hardening time of 24 hours) and 1 hour after.
Step 1: What Do You Need?
1. Half of a coconut shell, cleaned of all fiber
2. A disposable plastic bowl - slightly larger than the size of the coconut shell
3. Measuring cup
4. Silicon Spray(or any other lubricant, Vaseline would work just fine...)
5. 4-8 Self-adhesive Clear Rubber(or silicon) Feet Bumpons - You can find this here
6. Two-Part Clear Casting Epoxy (amount according to step 2). Colorants for Epoxy (optional)
7. Medium flat bottom, wax free measuring container. + Mixing Stickam
8. Plastic Funnel
Step 2: Find Out the Amount of Epoxy
- Measure the volume of the coconut by filling it with water and transferring it into the measuring cup.
- After measuring the coconut, measure the volume of the disposable bowl by filling it with water and transferring it into the measuring cup.
- Subtract the volume of the shell from the volume of the bowl
- You've Got it! that's the volume of Epoxy you need!
Step 3: Preparing the Coconut Shell
Apply at least 4 Rubber Bumpons around the top part of the coconut shell.
This will help the shell keep distance from the edge of the bowl
Step 4: Preparing the Bowl
Apply silicon spray or any other lubricant to the interior part of the plastic bowl.
This will prevent the Epoxy from sticking to the bowl. make sure to apply to the edges of the bowl as well as the bottom.
Step 5: Place the Shell Inside the Bowl
* Make sure the coconut shell is slightly spaced away from the edges of the bowl. if it's not spaced properly, re-adjust the Rubber Bumpons and try again.
Step 6: Preparing the Epoxy Resin
Now that we know how much Epoxy we need(step 2), lets start mixing!
Epoxy resins come in two parts: resin (usually marked A) and hardener (usually marked B). The two parts must be mixed in the precise ratio given in the manufacturer’s instructions (usually the ratio is 1:2 for the resin). Imprecise measuring and mixing prevents the epoxy resin from solidifying or curing.
Note: colorants can be added to the epoxy, clear or solid. The amount needed is given in the manufacturer’s instructions.
1. Carefully mix the amounts of resin and hardener into the mixing container. If you wish to color the epoxy, add the colorant to the mix.
2. Stir gently. vigorously stirring may introduce air bubbles into the mix.
3. Continue stirring until the color and texture are unified.
Step 7: Casting the Epoxy
1. Carefully pour the epoxy mix into between the bowl and the coconut shell using a funnel until the mix reaches the rubber bumpons.
For best result, pour the mix from different points around the shell.
After Casting - Gently tap the side of the bowl to extract air bubbles.
2. Leave the cast to harden for 24 hours. have a few cookies :)
Step 8: Extract the Mold
Once the cast has fully hardened, gently extract the mold from the plastic bowl.
Step 9: Sanding the Edges of the Bowl
Now you have a stunning coconut shell bowl!
When casting the epoxy between the bowl and shell, seeing as we cast up to the rubber bumpons we have a bit of extra coconut shell left.
Using the Polisher, sand the coconut shell up to the edge of the epoxy cast. once you reach the edges, you can use sanding paper for finishing touches(if you do, do not use sanding paper that is rougher than 150 grit size).
Note: This is not a tool to play around with, be careful! if you are using a hand held polisher - be sure to secure the bowl to a stable surface.
Step 10: Yay! You Did It!
Awesome! you are now the proud owner of a unique coconut shell bowl! have another cookie...
