Break away beer bottles!

Step 3: Cool it

In the DVD the instructor advises to let the resin in the mold cool for 20 minutes.

I however found I could get away with 10-12 minutes.

One word of caution if you pull your mold halves apart to soon , the bottle will collapse into itself. And you'll have to break the bottle down and remelt and pour it all over again.

Once you do pull the bottle out, do not put it on cold tiles or metal pans. This resin is soo brittle that a thermally conductive surface like a cool metal or tile will cool the resin too quickly and can cause heat fractures. I woke up in the middle of the night once to a crack and pop sound. The next morning the bottle was cracked at the bottom and fell over. Put it on wood or a warm surface and let it slowly cool.
