This is a 5-pound bag of Bucket Mold (390) Alginate.
390-S2 (3 minute @ 90 degree water) is one of Accu-Cast's oldest "bucket mold" formulas for hand casting. It is so good that it doesn't need improving- but we did anyway. This is now our smoothest, easiest to mix alginate formula for outstanding detail in the casting.
Bucket Mold (390)Alginate is Alginate at its Best
Still a reliable performer, 390-S2 has a 3 minute set when using quite warm 90°F water. If you use 70°F water this can be extended to about 4 1/2 minutes.
It mixes smooth and thin, pours easily but sets snappy and firm. Skin level detail is outstanding and shrinkage is very slow.

Five pounds is enough to do 3 double adult hand castings in a 1 gallon bucket.
