Draw a circle on a piece of paper with a diameter of approximately 10cm
Mark a quarter segment, then cover the whole thing in cellulose tape
Cut out the circle (you don't need to be too precise)
Make a cut to the centre of the circle along one of the quarter lines
Apply a strip of double-sided tape along the inside of the other quarter line
Fold the circle into a cone and secure it with the double-sided tape
Cover the seam on the back with more tape
This is a 65mm silicone sphere mould, but you can use any size
For this project I'm using my usual clear epoxy art resin, which has a 2A:1B mix ratio by weight
About 24g should be enough for the cone
Support the cone in the bottom half of the sphere mould, and fill the cone almost level with it
Allow that to cure until solid
When the cone has cured, you can remove it from the paper mould
It really doesn't matter if the cone has a few wrinkles
I'm using Mod Podge adhesive, but you can use any suitable alternative that dries clear
Paint a spiral of adhesive from the point of the cone to the bottom
Allow enough room for another couple of lines in-between
Cover all of the adhesive in fine glitter. I'm using silver holographic glitter to begin.
When that has dried recover the excess glitter to use again
Paint a second spiral of adhesive under the first one
This time I'm using violet glitter
Paint a third spiral of adhesive to fill the remaining gap
This time I'm using black glitter
Finally, coat the entire cone in adhesive and cover it with the glitter colour of your choice. I'm using black again.
The cone part is finished, leave it to dry completely
It will take about 75g of resin to fill the bottom half of a 65mm sphere mould
Fill the bottom half of the mould almost to the top. Don't allow it to dome.
Let that cure until firm
You will need about 50g of resin for the final pour. First apply a thin layer of resin to the surface of the half-sphere.
Use a flame to pop any surface bubbles, then place the cone face down onto the resin
Fit the top half of the mould into position
Completely seal the join with hot melt glue. Yes, I forgot.
After starting to fill the mould with resin, I soon remembered to seal it when I spotted resin seeping through the join.
There, sealed, as if by magic :)
Fill the mould almost to the top. The void area at the top shall become the base of the paperweight.
Allow that to fully cure
Once cured, you can remove the piece from the mould
Trim any resin flash with flush cutters, and give it a polish with polishing paste and a soft cloth.
The point of the spiral looks like it extends beyond the base of the sphere
Thanks for watching!
[Alexa] I can't believe you forgot to seal the mould
[Alexa] And it's not the first time either
