[QUOTE="JMN, post: 316198, member: 8469"] Hydrocolloid is largely water, no surprise there right? In order to keep the hydrocolloid from drying out and being inaccurate where it contacts the model, presoaking the model makes sure it is full of water as it can be so it doesn't pull water out of the hydrocolloid or pull hydrocolloid into the model. Tricky part is the model will start to break down after being wet too long, so that's why it's also a bad idea to leave them any longer than necesary. [/QUOTE]
