It was well-known by glass founders that glass annealing in presence of acid gases resulted in improvement of its properties [1]. The effect of acid gases on inorganic glasses leads to their dealkalization, reaction products are on the glass surface as a bloom. The changes in structure and composition of surface layer accompany the increase of glass chemical durability by 10–50 times, mechanical strength increases by 20–30 %, thermostability improves by 5–10 % [1–3]. The effect of magnetic fields on chemical interaction between acid gases and inorganic glasses has not been described in specialized literature. The aim of the present work is to study the possibility of intensification of the dealkalization process of industrial glasses with acid gases using impulse magnetic field.  Experiments were held in laboratory and industrial conditions. The objects of investigation were flat glass samples, bottles and jars of colorless glass, bottles of green glass, ampoules made of medical glass, illuminating glassware made of transparent colorless and milk glasses. SO₂, CF₂Cl₂, CHF₂Cl and mixtures of these gases were used as gaseous reagents. The procedure of thermochemical treatment in the laboratory conditions was carried out in the following way. Samples of glass were inserted into the kiln at room temperature. Then the samples were heated to the designed temperature and treated with gas reagent and impulse magnetic field. After treatment the samples were cooled in the kiln to the temperature below 100 ⁰C. The regimes of glass treatment are the following: temperature – between 300 and 600 ⁰C, value of vector’s magnitude of the magnetic induction – up to 0.15 T, duration – between 5 and 120 min, quantity of gas reagent feeded into the camera – between 0.01 and 1.00 mol. The main regimes of the thermomagnetic treatment of glass containers in industrial conditions were the following: temperature – between 500 and 550 ^oC, the value of vector’s magnitude of the magnetic induction – up to 0.15 T, duration – between 1 and 4 s, volume fraction of gas (gas volume vs. container capacity) between 0.1 and 10.0 % .  The intensity of glass dealkalization by gases was estimated using the extraction rate of alkaline cations [3]. The experiments studied the influence of temperature, chemical composition of glass and gas media, quantity of gas reagent feeded into the camera and glassware, duration of treatment and value of vector’s magnitude of the magnetic induction on dealkalization rate of alkaline cations. During the first stage of investigation we determined the rate of dealkalization of industrial glasses with different gaseous reagents based on the optimal regime of thermochemical treatment in laboratory and industrial conditions. In the following experiments the thermochemical treatment was repeated, but under the influence of impulse magnetic field. We have determined that the rate of dealkalization of industrial glasses with gaseous reagents under the impact of magnetic fields has increased by 2–3 times. It has been established that with increase of temperature, quantity of gas reagent feeded into the camera and  glassware, value of vector’s magnitude of the magnetic induction and duration of treatment of value dealkalization rate of alkaline cations of industrial glasses grows up.
