Human Grade 10mm Borosilicate Glass Slitted Diffusion Down Stems
HUMAN GRADE Welcome to the store Human Grade!! It appears that you will fit in nicely. I honestly cannot find much about them, they appear to be quite new and I am dipping in my toes to see what they offer. An American brand with a strong focus on budget, quality and detail, crafting handmade pieces of glassware. Durable and minimal design. I do plan to include more of their lineup soon. DIFFUSION DOWN STEM All bongs, bubblers, rigs (what ever you call them) come with a down stem as part of the setup, think of an enclosed pathway that links a flower bowl to a water chamber. Some are fixed in position and these can be quite simple in their design or they can culminate into an intricate percolator. Down stems that can be removed are quite useful for those that strive to keep their glass clean. I always recommend a slitted down stem at a minimum as a simple straight tube offers minimal/no diffusion. These down stems are made entirely from borosilicate glass with 6 slits total along the base. These slits will offer a basic form of diffusion, helping to break up smoke for filtration to occur. One large bubble of smoke transforms into a multitude. These slits will accumulate gunk and you can easily slide them out for a quick clean. Let's discuss measurements... Each stem regardless of length will insert into an 18mm female connection point and each can hold a 10mm male flower bowl. There are many lengths available and it is quite important that you select the correct length. Once in position within your bong, the base of the stem should land near the middle of the chamber closer to the base. Just ensure that smoke will pass through and will shoot out directly into water. Each length (3, 3.5", 4" etc) relates to the entire length of the stem, insertion point included.
