About

L.G.P. International (short for Laboratory of Glass Properties) is a R&D company providing services and performing developments in several areas related to glasses and other inorganic materials. The major areas of L.G.P. expertise are:
1. Precise measurements of physical properties of inorganic glasses, melts, ceramics and other materials within the temperature range from 20 to 1650oC. The range of testing services includes but not limited by:
- Viscosity
- Density
- TEC
- Specific heat
- Thermal conductivity
- Surface tension
- Chemical durability
- Electric conductivity
- Absorption spectra
- Structural relaxation
- Stress relaxation
- Spectral reflectivity and emissivity
- Radiative thermal conductivity
- Dielectric constant
- Chemical analysis
2. Development and building precision measurement devices, such as:
- Dilatometers
- Viscometers
- Relaxometers
- Spectrophotometers
3. Development of new glass compositions superior to the existing analogues
4. Development of computer models capable of predicting properties by composition,
processes of glass melting, forming and annealing, materials by the way they made
L.G.P. International works in the area of glass science and technology for over 30 years (as research unit - from 1963 to 1993) plus for another 20 years (1993 till now) as R&D Company.
L.G.P. International. LLC has two locations. Material development and testing facility, computer lab, and instrument designing workshop are located in St. Petersburg. Business unit is located in Farmington Hills, MI.
L.G.P. International accepts orders from Companies, Institutions, Universities, and individuals interested in testing inorganic materials, developing innovative high-performance low-cost materials, unique analytical instruments, and efficient computer modeling software.
