Epoxy resin.. again.

**Tuomas** · Oct 24, 2019, 07:39 AM

Hi

I made this kind of gift for my friend.

Its a bottle inside epoxy resin.
I tried to shape it to look like ice block.

I also made this small ice axe to it, so he can dig the bottle out. ( Try to dig )
Handle is about 3 1/2" long.

Here is the "ice block" after polishing.

Tuomas,
Thanks for the share.

I clicked the link and got to your channel, but could not find anything related to this project - though there are a lot of interesting videos there.
Should there be something or is this link just your signature tag?

Its just a signature. There's no video from this.

Here it is with lights on.

Tuomas,
I am curious about your method used in this project. As I understand, most epoxies generate heat while curing. I’ve seen pure resin (no additives) slabs of just 40mm crack from thermal stress. How do you prevent this?

(Also, awesome outcome!)

Nice idea to use bottles!

It was casted sideways.
Also i vibrated the mold at the beginning with oscillating tool.
Then when it "tried" to boil, vibration raised bubbles to the surface and that prevented it to boil too heavily.
Also hardener was slowly reacting. That, i think was the most important thing.

This could have been somewhat good subject for to make a video.. but i tought that people have seen enough epoxy stuff.

Now.. i think that i should have made that video.

A company I used to work for made epoxy encapsulated electronics. To use solid epoxy would be expensive and there's that heating problem. So, they partially filled the enclosure with fine, baked sand, vibrated and then poured the epoxy over it. Put into vacuum chamber to get the air out and then let cure.

Seemed to work well, the epoxy would be pulled deep into the sand.
