How to make sculpture sludge dry and harden?

After the sculpture sludge is air-dried, let it dry.

Characteristics of sludge:

1. It is hard and delicate at room temperature, and can be finely crafted. Suitable for making high-quality prototypes and industrial design models.

2. It is sensitive to temperature and can be softened, shaped or repaired at a slight temperature.

3. The new product is carefully carved with clay, which can be softened by hand temperature, easy to form and suitable for classroom teaching.

4. It does not touch hands or shrink, and it is cleaner and more precise than the net, which is a good material for handicraft industry to make prototypes.

How to use sludge:

1. The new product slices are finely carved with clay and can be kneaded by hand.

2. Two pieces of glue can be laminated by softening the surface with a hot air blower.

3. The molded thick block is very hard. If plastic surgery is needed, it can be packed in a heat-resistant plastic bag, soaked in hot water or put into a tube and softened with an electric cooker.
