In 1921 Soviet authorities built a new glass plant plus a wine and spirits factory. In the years following several more factories were added, including the "Red Metalworker" iron-working plant (1925), the silk spinning plant (1928), a cotton spinning plant and textile plant (1929), candy factory (1930), garment factory (1933), shoe factory (1934), and a meat cannery (1938). As of 1948, Ashgabat boasted "about twenty large factory-plant enterprises, which produce fabrics, glass, footwear, garments, meat products, dredges, agricultural implement parts and much else."
