Does the metal container needs to be close?

[alexpa...@hotmail.com]

I am ready to sinter some parts that i have printed with my lulzbot taz 5. However, i am wondering if the metal container that i will use to put the part in with the black magic powder/water should be airtight or i can simply let the top of my cylinder open and it does not matter? Ive read alot and look at the videos presenting the kiln process but it still unclear to me if i should use a closed container or no.

Thanks

Alex

nope doesn't need to be air tight, yhou can find the proper mixing for MBP right here in this forum, we use cut up tail pipe at the foundry works perfectly
