I was reading through a document on line that is Alfred Duhills application for a patent files on Oct. 14, 1918. Then patented May 25, 1920. It details his ideas on oil curing. My thoughts are actually a question I pose to you as a NON hostile debate. Some say it is only a process to faster cure the briar in question, and the benefits of the process soon wear off after a few smokes. Still I have read where folks say there is NO real benefit to this process. So my fellow & lady pipe smokers----what say you on this subject????? P.S.---just thought I'd start a new discussion subject.
