If you want lower viscosity from your epoxy, you can heat in a microwave. With 2 oz bottles, 10-12 seconds for one and 16-18 seconds for the other (sorry I can't recall which part takes longer--heat them both for 10 seconds and one will be much warmer than the other) Be sure to note that it's just a few SECONDS of nuking. This probably speeds up the curing a little, but it makes getting rid of bubbles easier, and for vase or goblet uses, faster curing is a plus. Also be aware that the components will run out of the bottles--you don't have to squeeze--so be ready. For smal amounts, I hold the bottle horizontal and let it drip, drip, drip out, counting the drips to get equal parts.
