Bog End

This terrain piece is somewhat experimental, inasmuch as I wanted to try out using very cheap (and pretty terrible) 5-minute epoxy resin for the water effects. I wanted something to go at one end of my river pieces (here and here), so they don't necessarily have to go from edge to edge of the table. The water doesn't match those pieces though, so that may not be a goer — I'll just have to see how much the difference scrapes on my nerves when the pieces are actually in play.

The no-name epoxy I used was some I found on a clearance rack at a local hardware chain store, for about three bucks per 50ml syringe. At that price, I figured I wasn't risking much except my time if it didn't work. I mixed it along with about 5-10ml of acetone to thin it, and I added some sepia acrylic ink — far too much, as it turned out — to colour it.

The results are as you see, only partially successful. With the acetone and ink added, it took a lot longer to cure than it said on the label, but that was a good thing as it gave me more working time to nudge it into all the nooks and crannies. In very shallow areas, close up against the flocking, it has greyed out somewhat. I suspect that's because the PVA I used to seal the flock wasn't fully dry, and some of it has migrated into the epoxy. It's not a tragedy for this piece, because it just looks like muddy, swampy muck, but it would have been problematic if I'd needed clear water throughout.

Whether it was because of the additives or not I don't know, but when it cured, this epoxy developed a waxy bloom that had to be wiped off. I was a bit relieved when I found that it could be wiped off.

The epoxy has one advantage over the polyester casting resin I've used, and that is that it doesn't smell, but that's it's only advantage. It is much thicker, and really does need the addition of acetone to make it usable at all, and it creates a pronounced meniscus as it cures. It doesn't create the slight surface ripple that the polyester does, so it doesn't look as convincingly liquid.
