One thing I found out when we bought the Asbestos Palace is that asbestos is in everything made between the 1930s and the late 80s, including the ubiquitous ceiling covering. Cornflakes were probably asbestos-based for a while. There's actually no guarantee that the replacement fibrous fire-retardant materials are that much safer (this is an often overlooked problem, we replace things with known risks with things with unknown risks*), but manufacturing and handling have vastly improved through the dreaded health and safety and its insistence on saving lives.
*not an argument that we should have stopped using asbestos decades before we did, the dangers were long known, just a general principle.
