Anyone here decarb in a mason jar in the oven?

Implosion isn't he concern. Explosion is the concern. Steam can and will create a lot of pressure inside the jar. Maybe the jar will contain it. But if it doesn't, you have glass shrapnel.

Not a safe practice. Even a pressure cooker or water heater will explode if you defeat the safety release. Just google myth busters water heater to see what can happen.

Bad advice to recommend putting a sealed glass jar in an oven. Sorry.

Most techs say to disacate weed before decarb
Once weed is disacated ( I.e. Remove moisture as in dry)
It can go into a seal jar.
In order to make enough steam pressure to "explode" a mason jar
You'd need some water in the bottom of the sealed jar.
I get what your trying to convey so yes
If you put 1/4 cup of water with your weed that will increase the chances of explosion.
Years (many many too many) ago being new to decarb I put 1/4 oz fresh
Cut in a sealed mason jar into the oven to decarb.
New to decarbing at that time
250 f degrees- 90 mins........,
No explosion but nasty baked weed
So stoner can follow the tech = no explosions
If stoner add water to the tech the possibility of explosion goes up...

If you leave the lid 1/4 turn loose (like when canning in a water bath) it will be fine. I use my pressure cooker to decarb and it works great!

You absolutely can use a mason jar for decarbing with a few caveats.

-DO NOT use the oven. Explosions or breakage occur in glass because of quick fluctuations of temperature - which can occur simply through the cycling on and off of a traditional oven, that is enough temperature variation to cause glass breakage.
-What you can do is set up a double boiler or follow traditional canning techniques. Either way, you want to avoid rapid temp change. I'd add the mason jar to cold water and then slowly heat it up to the decarb temp you are aiming for using a candy thermometer to monitor water bath temp.
-A safer way to achieve the same results, is to vacuum pack the weed (sous vide) and stick it in a water bath which I've used before. Easy and no smell at all.
-One potential issue is that some old timers claim dry weed is best for making Green Dragon or tinctures, and using a mason jar (or sous vide) will result in no change of moisture content. I've had excellent results with moist weed using the isi rapid infusion method, which if I understand the chemistry correctly, moisture content is not an issue for that technique. Other techniques, moisture content might be a factor, in which case the ole' fashioned baking in the stove would be the way to go.

What are these cookie sheets you speak of.

But a cookie sheet is what I use. 55 minutes at 225F. Then several hours in the crock pot with the coconut oil.

I ate two small slices of canna yellow cake a couple three hours ago {here at work}. Note to self. One slice is plenty.
