450 g KOREST ceracell fiber component (plastic fiber with KOREST ceracell)
10 g methyl cellulose or 100 ml Tylose® solution
Material for mass production of a supplement for large defects in porous ceramics (Tongut such as earthenware, majolica, faience, etc)
KOREST ceracell-F is so malleable, ductile and modellierfähig such as clay, so that it also quickly and easily replicas of sculptures and vessels can be made.
Properties of the supplement composition ceracell-F
Color: cream white
Dyeable with colorants (pigments) by addition to methyl cellulose solution
- Liability: At all, dust and grease free, porous surfaces
- Shrinkage: about 0 %
- Strain: about 0 %
Storage wet mass: in plastic foil, in a tightly closed box next to a wet sponge
Mohs hardness (after curing): 2 - with fingernail scratchable (such as gypsum)
Drying time (depending on temperature, humidity and thickness of the supplement: about 5 to 12 hours
After drying application of KOREST ceracell-G as Engobe with brush for smoothing the surface (2 - 3 layers between them easily grind).
Surface decoration is possible with all Retouch Colours and resin glazes
Reversibility after curing: continuous water
Instructions for the preparation and processing of KOREST ceracell-F
Preparation of methyl cellulose solution
- Sprinkle 2 g methyl cellulose powder in 100 ml distilled water, stir and leave to soak overnight.
Preparation of a bulk mixture KOREST ceracell-F
- 4.5 parts by weight of fiber-chalk mixture into 1 part by weight of methyl cellulose solution mix (2% in water).
Give 100 g methyl cellulose solution in a mixing bowl and sprinkle about half of the 450 g fiber-chalk mixture and stir with a plastic spatula. The remaining part of the fiber mixture is then poured chalk in a suitable plastic base (tray). The mixture of the bowl is given above and the mass kneaded well until a homogeneous mixture is obtained. For kneading is recommend to use Rubber gloves.
The mass bale is now wrapped in plastic foil and stored in einr tightly closed box with a wet sponge at least some hours. The material is then kneaded again and is ready for processing.
Processing of KOREST ceracell F mass
Larger faulty areas are deposited with base wax, or sticky tape. The mass is applied using modeling tools or by hand. The mass piece is to be applied at ceramic previously dipped briefly in distilled water, so that a fine slurry coating forms on the surface. Ensure good adhesion is achieved on the surface of the ceramic shard approach.
The surface can be smooth with platelet silicone; also moistened modelling instruments, brush or natural sponge can do this.
For the production of moldings, the mass may be put into silicone molds. In this case, a beautiful smooth surface of the shape is achieved.
These shapes can be coated with slurry (diluted with water ceracell-F -mass) on the ceramic or supplemented areas.
Cured mass can be sanded, carved and shaped with wet brushes or sponges on.
