View this post on Instagram Gas light in Oakworth Station. The fragile incandescent ceramic gas mantle seen here enveloping the gas flames produces much brighter whiter light than the bare gas flame would, was only perfected in 1891 becoming widespread until electric lighting. Mantles are fascinating, being a flexible fabric soaked in cerium and (radioactive!) thorium dioxides until installed and set on fire the first time when the fabric burns away and the ceramic forms. They used to be tied to the lamp with asbestos thread to complete the set of healthy materials 😕 #gaslamp #gasmantle #welsbachmantle #gaslight #railway #kwvr #oakworth #preservedrailway #oldlamps #thorium #radioactive #waitingroom #steamtrain A post shared by John | Exploration and history (@merrytrek) on Jul 9, 2019 at 3:22pm PDT
