Far too much water dentists like alginate very thick as this gives better impression results. Reduce the water and then you have a the thicker the mix.
You should not make impression in this way because it's very difficult way and bad way therefore you should go for easy way then you can make improvement for your channel and your patients

Very poor technique; no need to smooth with water, no need to place material with your fingers and there should NEVER be any alginate on the patient's face.
they generate heat (exothermic property) which will make them sets faster if you add all powder one short. And therefore, the working time will be shorter. So if you add by increments, lesser heat generated compared to like mixing all the powder together.
Where did you get the slab of glass? Would one be able to use a Pyrex rectangular baking dish, I saw one in Walmart the other day, by turning the dish upside down and mixing the chemicals on the bottom of the dish?
I am puzzled by these zinc phosphate videos. Glass is a great INSULATOR (inhibits the transmission of heat). That would make it just about the WORST material to draw heat away from an exothermic reaction. Seems to me they should use a block of metal, ceramic, or marble. Then after getting the cement prepared, how long is it workable? How long until it cures? Can it be applied to a wet surface? Can the excess be removed easily?
