Today I added the third and final layer on my most recent batch of coasters – the water layer. Usually I do the water layer second, but I wanted to see how it would look if I applied it last. Hopefully we will see good results (in the next day or two, after it cures). For now, these are the basic steps I took in pigmenting the water and layering it in the coasters.
I mixed up about 8 ounces of resin, then poured about 2-3 tsp in three cups for the three different colors of resin. This turned out not to be anywhere near enough resin and I ended up mixing another batch of 200 ml later.
After pouring the clear layer, I gently blow the resin with a heat gun in order to remove any air bubbles that form. A few are OK, but I think too many bubbles detract from the final look of the piece.
I need to stay close to the coasters I poured for the first hour or so after I pour them in case some bubbles emerge that need to be removed. For this, I use a heat gun, though many people prefer a craft blow torch. Hopefully everything will cure / harden nicely overnight and we can see how they turned out tomorrow evening.
