Photoluminescent Pigment For Ceramics
Photoluminescent ceramic tiles are made by pressing clay, powdered quartz and feldspar, silicon dioxide, photoluminescent pigment, etc. into the embryo body and firing. The product has all the characteristics and functions of ordinary floor tiles, and also has a self-luminous function.
MINHUI's photoluminescent pigment is non-radioactive, non-toxic,very weatherproof, very chemically stable and with a long shelf life of 15 years. After absorbing light for 10-30 minutes, it can continue to emit light for 12 hours in the dark, and the process of light absorption and light emission can be infinitely cycled.Glow in the dark ceramics made with our pigment has long afterglow, high brightness, excellent weather resistance and wear resistance, and long service life.
MINHUI's MC series photoluminescent pigment is a branch from our MH pigment. MC series pigment is specially developed for firing in high temperature and are perfect for making beautiful glow in the dark ceramics. MC series photoluminescent pigments are made from alkaline earth strontium aluminate, which present themselves in light yellow and whose luminance colors is yellow green or blue-green. This pigment range features high hardness, excellent oxidation resistance under high-temperature, always recommended for ceramic or glass industry which need hard fire.
For luminance statistics of MINHUI's pigment, please see Specification.
MH serie's photoluminescent pigment meets the US requirement of ASTM F963-16 (Standard Consumer Safety Specification on Toy Safety), Test Method CPSC-CH-E1003-09.1 for total Lead, and ASTM F 963-16 (Clause 8.3) for soluable heavy metal; and registered for EU REACH standard in accordance with the REACH regulation (EC) No 1907/2006.

Photoluminecent pigment can be mixed with resin, paint, plastic, glass, ink, nail polish, rubber, silicone, glue, powder coating and ceramics to make their glow in the dark version. It has been widely applied to fire-fighting safety signs, fishing tool, craftworks, jewelry, watches, textiles, toys and gifts, and so on.
Below is our brief introduction on how to make glow in the dark ceramics.
1. In general, try to choose the transparent glaze and finished white brick with low firing temperature.
2. Depending on the luminance level and glow time you want to achieve, the ratio of transparent glaze and the luminous powder can be from 4:6 to 6:4.
3. On top of the mix glaze, cover a layer of transparent glaze again.
4. For yellow-green pigment, we recommend you to control the temperature below 850 degrees Celsius; for blue-green pigment, we recommend you to control the temperature below 1050 degrees Celsius.
