Why Mesothelioma Cases Occur in Marshall
Marshall Pottery, operating continuously since 1895, is one of the oldest pottery and ceramic manufacturers in Texas. Ceramic kilns operated at 2,000°F+ and were historically lined and insulated with asbestos-containing refractories, gaskets, and kiln furniture. Kiln operators, kiln builders, and maintenance crews worked in environments saturated with asbestos dust throughout the early and mid-20th century.
Eastman Chemical Company Texas Operations, located about 15 miles west of Marshall in Longview, has been a major regional employer since the mid-20th century. Eastman's chemical processing equipment, reactors, heat exchangers, and distillation columns used asbestos insulation and gaskets extensively through the 1970s and early 1980s. Many Marshall residents have commuted to Eastman for their careers.
Historic Texas & Pacific (T&P) Railroad maintenance shops operated in Marshall from the late 19th century well into the 20th. Locomotive boiler repair, brake shoe work, and rail car maintenance routinely involved asbestos-lined gaskets, brake pads, and boiler insulation. T&P Marshall shops were one of the largest rail maintenance facilities in East Texas.
Additional exposure sites include Thomas Haltom Ceramics, Louisiana-Pacific / Roseville-Marshall Ceramic Products, and the broader East Texas industrial corridor that connects Marshall to Longview, Tyler, and Kilgore. The oilfield services industry supporting the East Texas oil field also used asbestos-lined equipment extensively through the 1970s.
The 20-to-50-Year Latency Period
Mesothelioma does not appear immediately after asbestos exposure. The disease has a latency period of 20 to 50 years, meaning workers exposed in Marshall-area facilities during the 1950s, 1960s, and 1970s are being diagnosed now. A tradesperson who worked around asbestos insulation in Marshall in 1970 may only receive a mesothelioma diagnosis in 2026 or later. This long latency period is why Marshall continues to produce new mesothelioma cases decades after asbestos use was curtailed.
Marshall's Asbestos Legacy by the Numbers
Marshall Pottery has operated continuously since 1895 — more than 130 years of ceramic kiln operations. The T&P Railroad shops operated for nearly a century. Eastman Chemical in nearby Longview employs thousands across East Texas. Texas allows 2 years from diagnosis to file a mesothelioma claim.
