Mixing: Start with 33% water as each colorant takes a different amount of water, cobalt carbonate needing a good bit more than the others. Add more water in smaller increments as the paste can quickly become over hydrated and sticky. Paste tends to stiffen up by the next day or two and will need to be re-wedged to become pliable again.
