I have been seeing pipes with Bakelite stems. Ashton is using this material of construction. Are there any opinions out there? How does this compare to acrylic or vulcanite?
Yeah, I have pipes 100 years old with ruby red Bakelite stems that are still ruby red. There are some amber versions from that period that are a bit softer. And there are later formulations that feel and react a bit differently. But historically, Bakelite is pretty much gone on pipe stems by the '50s in favor of nylon and later acrylic. The Ashton white stems are supposedly 1930s Bakelite. But I've never seen a 1930s pipe with a white Bakelite stem. I'm not sure what all that means. But I'm skeptical without knowing more about the provenance of the material.OK, splitting hairs. It darkens with age, but doesn't turn yellow from the sulphur like vulcanite, which is what pipe people mean when they refer to stems oxidizing.
That says Bakelite. But it looks like modern acrylic to me. In my mind Acrylic and Bakelite, though both are technically plastic, are very different materials. Seems like the terms are being used interchangeably.Right here on pipes2smoke.
I do agree that bakelite does oxidize but in my, admitedly, limited experience it's a very slight oxidation even on +/- 100 year old pipes. I only have a few of these but all of them had just a hair of oxidation when I polished the stems. Nothing even in the same universe as a vulcanite stem but it was there. Now as far as it being a vastly different color once the oxi was cleaned off, that hasn't been my experience. The difference was noticable but not drastic.Bakelite actually DOES oxidize, albeit slowly. It is common for pipemakers to come upon bakelite rods that are one color and a totally different one once cut into.
This unusual coffin is believed to be the largest phenolic moulding made in the UK. It was designed by James Doleman and made by Ultralite Casket Co Limited. The coffin was manufactured from imitation walnut phenolic resin with a wood flour filler devised by the Bakelite Company Ltd of London. The coffin did not go into large scale production, partly because of the inventor’s death in 1944 during the Second World War. This example was recovered from the Tyseley factory of Bakelite UK, near Birmingham, in 1985. The first synthetic thermosetting plastic was phenol formaldehyde. It was patented in 1909 by Belgian-born chemist Leo Baekeland (1863-1944) who had emigrated to the US in 1889. The substance forms a useful mouldable plastic when combined with a wood flour filler. It is known by its trade name ’Bakelite’, after its inventor.
That is interesting, and certainly possible. I only have three old WDCs so my body of experience with bakelite certainly isn't extensive. I wonder if different sources of material yielded differing results. Sort of like you see with vulcanite.So it's a very real phenomenon for bakelite to oxidize as quickly or even more quickly than vulcanite, but I think it's an intriguing natural aspect of the material.
I've had a couple catalin stem pipes. It's identifiable by being heavier than Bakelite. Proportionate to it's size, it has weight more akin to stone. The only color I've seen for catalin stems is yellow. And the color is surface deep. Trying to work toothmarks takes the color off. This is true of some Bakelite stems as well. But less so.Except when they were made from Catalin, a competing thermosetting compound (in this case a polymer) which was invented in 1927 by the American Catalin Corporation. My guess is that at least some of the radio housings shown could be Catalin.
