You have to keep mixing the components until the liquid forms. If you have a sludge, you will have mixed something, but not everything intimately, so you won't have the correct component ratio. The DES is not going to form spontaneously, so leaving it will not have helped.
We have had DES's remain as liquids for 6 months and counting.

We havent measured the viscosity, but if you tip it at 45 degrees, it takes over a second to level itself. If its mixed properly, it will become a liquid. We use automation, but old school is mortar and pestle. The literature frequently makes reference to using water to dissolve the solids, then evaporating the water (under vacuum may be better?) to leave the DES. DES properties can still be exhibited with small amounts of water, but obviously this composition change alters the properties vs the pure DESMore
Are there any good indicators that it is properly mixed? Like do you know what sort of viscosity should be attained with these particular eutectics? Can water or some other solvent, and/or heat, be introduced to improve the mixing?More
