I think the issue was never so much visible offgassing at is was people noticing flavors that they thought shouldn't be there
Point of clarification: There was indeed (as
@Archaicrevival has pointed out here, and older posts in what I think was the previous thread) an "offgassing" that was an issue with *SOME* of the first units.
That being said, there are several important points that need to be clarified:
1. It was not all units. I had several at that time, including a pre-production unit. I also had a lot of friends get a unit in the first months. NONE of the units I had hands-on had exhibited this issue. (I like to test things.) Only some of the units were affected.
2. The culprit was pointed to as an un-fully cured batch of silicone from a vendor. DV's response to this (
@Davinci_vaporizer -- I believe this was before your time, when S was here on site.), was to move all curing internally where DV could control it and not be subject to the whims of vendors over there. (Anyone that has done any manufacturing in China understands the end of that sentence.) Thus this:
We have an entire room here dedicated to curing the silicone. First it goes through a boiling treatment in a big crock pot like machine, then into an autoclave for a secondary cure. The units are also ran through a burnoff cycle here at 430 degrees for 10 minutes before being packaged.
3. Medical grade silicone. Any vapor might look scary, but it isn't. But if you were still concerned, a few burn-offs solved the problem for most.
In addition, on the taste front: I am foremost concerned with the flavor and tasted no negative impact. (Other than when I tried an essential oil that had ginger in it. Oh, boy, I couldn't get that taste out of my flower for weeks. Learned that lesson.
I keep on Ascent just for oils and other herbs.) A slight "new vape smell", but one will find that with most new anything. [I will note that there are those that have a sensitivity to silicone, of which I am not a member of said set. For them, it was more pronounced at first, but does dissipate.]
IIRC, there was some speculation that some of the packing materials aroma did creep into the device. But letting it air out for a while fixed that.
I took about half of a cotton ball, soaked it in water, squeezed lightly and pushed the wet cotton into the bowl, holding the Ascent upside down so excess water would fall out while the cotton was pressed in against the inner surfaces. I turned the Ascent on at 100 Celsius; actually a bit higher. The water in the cotton steamed and softened the baked bowl-brown. I did this with the glass stems in place and held the Ascent upright. Steam rose from the stem and water drops condensed within. I closed the oven. This could also be done with the oven open.
Brilliant, gentle vaporist. Brilliant.
