Liquid Glass Production
How Sodium and Potassium Liquid Glass is Manufactured
The characteristics of sodium and potassium liquid glass depend heavily on how the raw material for these solutions—silicate lump (cullet)—was manufactured. Furthermore, the technological process itself influences the final parameters of the compositions. Here is an overview of what is required to manufacture liquid glass from sodium or potassium silicate, as well as the specific details of working with these materials.

Manufacturing
The main components of liquid glass compositions are:
- Quartz sand (silica);
- Sodium carbonate (soda ash) or potassium carbonate (potash) (depending on which type of liquid glass is required).
GOST Standards
Sodium liquid glass at STEKLOLUX is manufactured in accordance with the requirements of the interstate GOST 13078-2021, which is in force in the Republic of Uzbekistan. This standard regulates the primary physicochemical parameters of the products and specifies the production of liquid glass with a silicate module of no less than 2.3.
In cases where a customer’s technological processes require low-module or non-standard compositions, production is carried out according to Technical Specifications (TU) developed by STEKLOLUX for specific application tasks.
Potassium liquid glass intended for the paint and varnish industry is manufactured based on GOST 18958-73, which serves as the regulatory and methodological framework.
If potassium liquid glass is applied in other industries, STEKLOLUX uses this GOST as the basis for analysis and control methods, while the specific product parameters are documented in the enterprise's Technical Specifications.
Ultimately, the quality and applicability of liquid glass are determined by the level of equipment, the precision of technological processes, and the manufacturer's quality control system. The STEKLOLUX approach is based on adapting products to real-world operating conditions and ensuring consistent characteristics from batch to batch.

Characteristics
How to select sodium or potassium silicate for your production tasks
At STEKLOLUX, the selection of silicate products begins not with a price list, but with an analysis of the customer's technological requirements. For liquid glass or potassium silicate to perform correctly in your process, several key parameters must be taken into account.
Primary characteristics for product selection:
The STEKLOLUX approach is based on tailoring these parameters to real-world operating conditions, allowing for a product with predictable properties and stable quality for your specific technological process.

Primary characteristics for product selection:
- Silicate module — determines the ratio of silica to alkali in the solution and directly affects the reactivity and the strength of the bonds formed.
- Solution density — affects dosing, consumption rates, and the operational stability of the equipment.
- Solution concentration — the content of sodium or potassium oxide, which determines the alkalinity level and the product's activity.
- Solution viscosity — a critical parameter for pumping, spraying, and ensuring even application.

Manufacturing Process of Sodium or Potassium Liquid Glass
Regardless of the purpose or type of product, the production of liquid glass fundamentally consists of preparing an aqueous alkaline solution and dissolving a silicate base within it. At STEKLOLUX, the technological process is structured according to an industrial scheme and includes several consecutive stages.
Main Stages of Production:
Raw Material Preparation Quartz silica raw material is used as the starting point. It undergoes crushing and grinding to a fine-fraction state, which ensures the uniformity of subsequent reactions.
Batch Preparation Alkaline components—sodium or potassium compounds (soda ash, potash, and other alkaline additives, depending on the required composition)—are added to the prepared silica. The ratio of components is selected based on the target silicate module.
Melting and Silicate Lump (Cullet) Production The formulated mixture is subjected to high-temperature melting at approximately 1200 °C. This results in a homogeneous glassy monolith—the silicate lump—which serves as the base for the further production of liquid glass.
Dissolution of the Silicate Lump The resulting lump is loaded into an autoclave, where it gradually dissolves in water at temperatures above 100 °C and operating pressures of up to 0.8 MPa. The process is carried out under controlled technological parameters to ensure the uniformity of the solution.
Finished Product Formation The result is a viscous aqueous alkaline solution with high adhesion and water solubility—liquid glass with predefined physicochemical characteristics, ready for industrial application.

Product Quality Control
Quality Control Process Adapting liquid glass characteristics to the specific technological processes of each customer means that product parameters can vary significantly between different clients. This is precisely why at STEKLOLUX, quality control is structured as an integral part of the production cycle.
Control is carried out with the participation of our production laboratory and experienced technologists. They verify that the key indicators of the liquid glass—such as silicate module, density, concentration, homogeneity, and property stability—meet the specified requirements. The evaluation is conducted with a focus on the real-world conditions in which the product will be used at the customer's site.

How much does it cost to buy potassium or sodium silicate, and what determines the price?
Since the parameters of sodium and potassium liquid glass are selected individually for each customer's technological processes, there is no universal price list. The final cost of products for a specific enterprise is formed taking into account several key factors.
Key pricing parameters:
Liquid glass characteristics
The cost depends on the product type and its parameters. Potassium liquid glass is generally more expensive than sodium liquid glass. Lowering the silicate module, or increasing the density and concentration of the solution, also affects the price. Given the vast number of possible characteristic combinations, it is advisable to select the optimal variant in collaboration with a STEKLOLUX technologist.
Logistics and delivery
Liquid glass is a product with relatively low margins; therefore, transportation costs can represent a significant portion of the final price. The location of STEKLOLUX manufacturing facilities within Uzbekistan allows for optimized logistics and reduced expenses when delivering to customers' industrial sites.
Storage conditions
Sodium and potassium liquid glass are sensitive to sub-zero temperatures. Freezing and subsequent thawing can lead to a partial loss of the product's functional properties. Therefore, when planning a purchase, it is important to consider transportation and storage conditions in advance.

Regarding the cost of liquid glass, it is calculated individually and depends on the solution's characteristics, delivery volume, and logistical specifics. On average, you should take into account that purchasing potassium silicate will be more expensive than sodium liquid glass—and the lower the module, the higher the cost of the liquid glass.
