"Origins of Sandblasting

In 1917, when Alfred Dunhill invented and then marketed the first sandblast-finished pipes, those pipes were sold for more than their smooth counterparts. (David Field wrote that early Shells sold for more than their bruyere counterparts. However, by 1932, they were priced at parity.) Presumably, Dunhill considered both the practical aspects of producing a sandblasted pipe alongside its function.

Though we can’t know what went through Mr. Dunhill’s mind, certainly, the introduction of a new finishing process in the factory involved the purchase of new equipment. For this reason as well as novelty – then, as now – innovation was usually accompanied by a higher price.

1952 Dunhill Shell Briar BilliardAlthough Dunhill chose to keep his pricing approach straightforward and simple, the introduction of the sandblasted finish was cost-effective. It enabled the factory to use a greater proportion of briar ebauchons because sandblasting and staining conceals minor to moderate pits and flaws. So those ebauchons that would not pass muster for smooth-pipe manufacture could be made, marketed, and sold as Dunhill Shell Briars.

We know now that Dunhill, at some point, decided to use Algerian ebauchons for his Shell line, because the briar is softer and produced more dramatic sandblast effects. Presumably, when he was importing turned ebauchons from France between 1917 and 1920, he may not have known the briar’s origins. (Dunhill began turning its own bowls in London in 1920.)

1928 Dunhill Shell PrinceThe number of ebauchons being turned in France at that time was astonishing. We know from Jacques Coles’ The GBD Story that 500,000 ebauchons (or 10,000 bags) were delivered to the GBD Factory in 1919 with 36,000 dozen bowls being turned per month. GBD was just one factory in St. Claude in those days. I have not been able to determine from which factory Dunhill ordered his ebauchons.

I have long mused on Dunhill’s name selection for sandblasted pipes. Recently, as I have been reading his 1924 tome, The Pipe Book, I discovered an illustration of a Polynesian Shell pipe on page 130. Was Alfred Dunhill reminded of those early Polynesian pipes when he saw the first sandblasted ebauchons? It seems possible to me, as the texture is so similar.

It is amazing to me just how beautifully detailed Dunhill’s sandblasted pipes could be. Unlike today, the sandblasting process employed early was not as controlled as those employed today, especially by artisans who have created a distinctive sandblasting technique and look. Ebauchons were put into a wire barrel where they rolled and shifted for several hours as the wood encountered the sandblasted media that was directed from a fixed nozzle.

Sandblasting has come a long way since Dunhill’s innovation.

The sandblast pipe has come a long way since the finishing strategy was originated by Dunhill in 1917. Today, various artisans’ approach to sandblasting has become yet another way that one maker differentiates his pipes from other makers.

In days past, sandblasting often resulted in unpredictable grain patterns and some loss of shape definition. The aleatoric element of the wire tumbler is a thing of the past. Significant intention is brought to bear now when artisans direct their sandblasting nozzles to accomplish specific textures and effects.

Today, artisans deploy their sandblasting equipment in order to highlight wood-grain structure and to enhance the complementarity of shape and grain. Among the options are ring blasts, crossgrain blasts, craggy blasts, spiderweb blasts, and hybrid approaches that combine aspects of the above to artistic effect.

Like many aspects of pipe making, creating a beautiful sandblast finish on a pipe is more complicated than it seems. It begins long before the artisan places the shaped bowl into the sandblasting cabinet. The best sandblasted finishes begin when the artisan decides how best to position the pipe within the briar block."

e bravo.... neke informacije koje nisam znao...

Sjajno.
