I just got an email from the fellow who sells the Strambach meers on ebay. I was asking specifically about the base material used for their pipes. Basically, pressed or not? Which one is it? His answer may clear up some confusion.
"Greetings and thank you for your inquiry,
The Strambach pipes are unique in material and are neither mined block or pressed meerschaum. Strambach uses a proprietary method of laboratory 'cultured' meerschaum. They simulate the process that forms natural meerschaum in a laboratory setting over a 2+ year process. This 'cultured' meerschaum is then carved and has many of the characteristics of 'block' meerschaum. Cultured meerschaum are lightweight, handcarved, colors from smoking, absorbs moisture, and have great smoking qualities. Strambach has used this process since the early 1900s and was even the supplier for the legendary Andreas Bauer pipes which are great smokers. Due to their cultured process being so unique it is often misunderstood and lumped into the same type as pressed (scraps of meerschaum ground and then glued together) because they do not use harvested naturally occurring meerschaum.
The problems with pressed meerschaum is due to the adhesive they use to press all the grindings together which prevents it from being porous so the smoking quality is not as good. Also, the shapes are limited for pressed meerschaum as they use molds after pressing the grindings and adhesives together instead of carving them like they do with block and cultured block meerschaum.
you will not be disappointed with the Strambach products, if you are looking to try one for the first time, my most popular model is a 'Student' pipe with bamboo that is smaller and only $69 here in my ebay store.
hope that helps,
Holiday Blessings"
