Flat glass for building materials. With a cooling rate of 530–550°C, it belongs to a different category than glass used for fusing. / Note: Because the melting characteristics differ, these types of glass must not be used interchangeably.
Flat glass for building materials. With a slow-cooling point of 530–550°C, it belongs to a different category than glass used for fusing.
Note: Do not mix these products, as they melt differently.

Standard flat glass (float glass; flat glass for building materials) is the type of glass commonly used in windows and other applications. Its annealing point is around 530–550°C, and it differs from art glass used for fusing in both its coefficient of thermal expansion and viscosity characteristics.
Because they are of different types, they cannot be melted together with art glass.
