It  had to be epoxy.  Glass is soluble in caustic soda (sodium hydroxide).

Around 1990 I took a tour of the GATX maintenance facility in Colton, CA. I recall the company tour guide told us caustic soda was the most problematic load they carried in their cars. He stated the glass (or was it epoxy?) lined tank cars would be good for about six loads before they had to be brought in, their interiors cleaned with metal shot and then relined.
