German Viskovita dental porcelain absorbent sponge uses high-density absorbent fiber, designed for dental technicians to control brush moisture during fine procedures such as porcelain build-up, glazing, and staining. During porcelain build-up, the brush is dabbed on the sponge after picking up water to remove excess liquid, ensuring the best powder-to-liquid ratio and preventing the porcelain from becoming too loose or collapsing. In the glazing step, the sponge quickly absorbs excess liquid from the glaze brush, keeping the glaze layer even and thin while avoiding runs or buildup on the surface. The soft material will not damage sable or nylon brush tips. Repeated dabbing keeps the brush shape, extending the life of valuable ceramic brushes. The material is degreased so no lint or fiber remains after wiping, which prevents contamination of porcelain powder or glaze liquid and protects the cleanliness of the restoration surface. The sponge can be rinsed and reused, regaining its loft after drying, making it a daily essential consumable for porcelain build-up and glazing in the dental laboratory.
Q: Can I replace this sponge with a regular cosmetic cotton pad
A: Not recommended. Ordinary cotton pads shed fibers that contaminate the ceramic surface, and their absorbency and feel are different. A professional absorbent sponge is degreased and density-optimized for the precision needed in build-up and glazing.
Q: How often should the sponge be replaced
A: It depends on usage. The sponge is reusable after rinsing. Replace it when it shows obvious damage or reduced absorbency, typically every few weeks to a few months in a busy lab.
Q: Will it damage expensive sable brush tips
A: No. The material is soft and elastic. With correct dabbing technique it protects the brush tip and actually extends brush life.
Q: Can it be used with the glaze brush
A: Yes. After loading glaze liquid, dab the brush on the sponge to remove excess, which helps produce a more even and translucent glaze layer.
