Hand casting is the process of creating a three-dimensional model of a hand using molding and casting materials. It's a popular way to capture precious memories or mark special occasions.

A hand casting kit typically includes a molding material (such as alginate), a casting material (such as plaster or resin), a mixing bowl, a mixing tool, gloves, and sometimes decorative items. Some kits also come with a practice kit or display stand.​​​​

First, gather all the tools you need. Prepare the mold by mixing the molding material with water and pouring it into a suitable container. Place your hand in the mixture and hold it still until it sets. When it hardens, carefully remove your hand without breaking the shape.

Common problems include fast-hardening alginate that causes loss of detail due to movement, bubbles on the surface of the skin, and fading in the shape of fingertips. To avoid these problems, it is necessary to mix the alginate evenly, ensure the correct position of the hand and carefully remove large bubbles.​​​​

Curing time can vary from 2 minutes to 5 minutes depending on the water temperature.
