Step 6Mix the alginate

Mix the alginate
Mixing the dermagel (dental alginate) is not quite an exact science. Although, it is fair to start with a base mixture of 1.5 parts water to 1 part dermagel by volume.

Once you have that base, mix thoroughly and see what the consistency looks like. Ideally, it'll have the consistency of cake batter. If it does not, add more dermagel until it does.

Mix vigorously until there are no clumps left.

It's important to know that the warmer the water is, the quicker the setting time will be. This could be helpful depending on what you are casting.

Figure that the normal setting time is between 15-30 minutes to be on the safe side.

I think I'd go with faster set time/warmer goop.
