Smojo Pipe Screen
Is Smojo safe?
Stainless steel has been used for smoking screens for decades with no health or safety issues. Smojo is made of surgical quality stainless steel and cannot be burned with a standard lighter. This steel has been extensively studied and is safe if used as directed. Do not touch Smojo when it is hot. (Smoking is known to cause a variety of health problems.)
Will Smojo burn? Why do I need to cure it?
You cannot burn Smojo with a standard cigarette lighter. Heating stainless steel will “cure” it by forming a protective crystalline passivation layer that acts like glass, and can’t be burnt. Smojo is made entirely of Type 304 Stainless, one of the most common types used for food service, medical and surgical equipment. (see: https://en.wikipedia.org/wiki/Stainless_steel).
What does curing the Somjo do and how do I cure my Smojo?
Some people believe in curing metals to remove impurities and/or to create a harder, tougher and more stable metal. Please note that all Smojo’s are made with Surgical Stainless Steel in the U.S. and are steam cleaned prior to packaging so curing is not necessary. If you wish, you can cure Smojo by heating it with a lighter, but rest assured that your Smojo will be cured through normal use. Technically speaking curing creates a layer of chromium oxide crystals on the surface turning the Smojo a metallic brownish. Chromium oxide melts at 2435 °C (per https://en.wikipedia.org/wiki/Chromium(III)_oxide)
Cleaning Smojo – Why does Smojo turn black?
As carbon based material burns, ash and resin are released and bond together to form a hard shell over the Smojo. This build up is what clogs standard screens. Smojo is designed to allow you to burn off excess build-up by heating the head red hot with your lighter then scraping it with a metal pick. Any remaining black ash / resin build up after this process
will not impact the performance of your Smojo.
Why doesn’t Smojo clog?
Smojo has no holes that can clog. It uses dynamic apertures created by the geometry difference between the Smojo head and the pipe bowl. These apertures change each time you use Smojo. If you cannot draw easily after cleaning Smojo, its time to clean your pipe!
How do I get my Smojo out when I want to clean my pipe.
If debris is blocking access to your Smojo, use a lighter and burn away excess debris. Wait 30 seconds for Smojo to cool then use the larger end of a paperclip to loop a round the head and gently pull it out of pipe. Strong tweezers or needle nose pliers may also be used to remove Smojo.
Why is more ash getting through the bowl than expected?
The Smojo brand of permanent screen is designed to fit and work well in most single-hole glass pipes. Occasionally the geometry of a glass bowl will be such that there is a larger gap between the long edge of the Smojo and the bowl. Many glass pipes have interchangeable bowls and replacing the bowl will eliminate the issue. In our testing we found that this affects a very small percentage of glass pipes.
