First Rule of Resin Casting …

The first rule of resin casting is to keep moisture away from the resin.  Any contamination & the resin will bubble and will create a flawed casting.  But what happens if water is deliberately introduced to the resin?  Will resin form huge bubbles?  Will the resin geyser like Coke with Mentos?

chem-plant-009The experiment mixed 1 part water with 2 parts resin.  The heavier resin floated to the bottom of the container & resisted mixing with the water.  Only after the excess water was drained from the container did the resin begin to set up.  I was disappointed that the resin/water mix only created a substance some thing like oatmeal.   No 10x expansion in volume.  No flowing river of bubbly resin.  Looks like I need a Plan B to make my toxic chemical soup.

The rest of the project is part of a terrain building surge for Adepticon.  The project will mix the Hirst Arts Pipe molds with Imex plastic kits and a bit of kitchen garbage including water bottles & soup cans.  The resin does serve one purpose – the fragile plastic bottle is now supported by the internal coat of resin.

    I thought the first rule of resin casting was not to talk about resin casting! Glad I was wrong…very nice terrain! What bottle is that from? It’s a very cool shape.

    The container is a water bottle from a product called “Aqua Pods”. I don’t normally buy bottled water, but the bottles looked too good as terrain pieces.

    You might try spray in styofoam. The cans you get at Home Depot or wherever that are used for sealing cracks and such. Spray into the bottle and it will spooze out the top…a really great effect.

    you could also try mixing an amount of baking soda into the resin, then pouring in vinegar. The idea being when the vinegar hits the baking soda, releasing c02 and forming lots of bubbles in the resin. Though that’s starting to get into the dicey area of messing with chemicals.

    That’s starting to sound a bit like a volcano. But I should give it a try – over a well protected work space….
