The Labino Formula : Manufactured in House
The Spruce Pine Batch “house” formula was designed by Dominic Labino specifically for use by studio glass artists. The Labino Formula is available in a variety of expansions and with or without decolorizer. The most popular version of the Labino Formula has a theoretical expansion of 87.3 x 10-7, with a measured expansion of 96-97 when melted. The annealing point is 482°C (900°F) and the softening point is 662°C (1224°F).

Agglomerated Glass Batch
Spruce Pine Batch is agglomerated for easier, safer storage and use. All materials are selected and tested for use by studio glass artists, not large factories. Spruce Pine Batch is prepared by weighing and mixing the materials which compose the formula of the glass, then processing to form larger granules from finer materials. The process is commonly called pelletizing although pellets are not necessarily formed. The primary purpose of agglomeration is the prevention of segregation of materials during shipping and storage. Furthermore, it has the additional effect of increasing safety by reducing the dustiness of the materials and when compared with loose batch, research has shown that agglomeration results in fuel savings and reduces furnace wear.
