Quartz Plate Q & A
Q: What's the difference between fused quartz and synthetic quartz plates?
A: Fused quartz is made from naturally occurring quartz, while synthetic quartz is grown in laboratories for higher purity and consistency.
Q: Can quartz plates be customized for specific applications?
A: Yes, most manufacturers offer customization for thickness, diameter, and surface treatments.
Q: How do I clean quartz plates?
A: Use mild detergents or specialized quartz cleaners; avoid abrasive materials that could scratch the surface.
Q: What's the typical lead time for quartz plate orders from China?
A: Standard products ship in 2-4 weeks; custom orders may take 6-8 weeks.
Q: Are quartz plates fragile?
A: While more durable than glass, quartz plates can crack under mechanical stress - handle with care during installation.
