Surface hardness and compressive strength are higher and setting expansion is lower than Hydrocal B-11, but has similar workability and setting characteristics.
ClayPeople
Hydrocal B-11
Low expansion and dimensional accuracy. Plasticity for more gradual setting action makes it more suitable for buildup or templateformed models.
Hydrocal White
White gypsum cement that can be carved or built-up. It is a good choice for finished pieces such as sculptures, lamp bases and architectural elements.
Hydrostone
Develops the highest compressive strength of any gypsum cement. Strongest and fastest superstrength gypsum cement available.
No. 1 Casting Plaster
Similar to 30 Minute Casting Plaster, but with a less porous surface because of surface hardeners added for strength.
Pottery Plaster No. 1
Highly uniform, noted for outstanding performance and long life. The standard of the industry, it is the best material available for slip casting or jigger molds.
Ceramical
Low consistency gypsum cement. Smooth wearing mold material for use in pressing clay ware. Characterized by low absorption and specified for use with RAM automatic form ing equipment.
Dental Plaster, Lab.
This is a general dental application plaster with a set time between 6 and 9 minutes.
