My brother bought a LEM MAXVAC PRO 1380 vacuum chamber sealer.
The PDF is online. When I am allowed to supply LINKs I will post it.
I found a video on the web showing how you can stack mason jars in a huge chamber
and suck down the vacuum in a dozen jars at once and the lids would stick to the glass so
I thought the thing to do would be learn how to attach glass tubes to the bottom of tje jar to hold the seal on electrodes.
I contacted the manufacturer and asked how much vacuum it sucks down .......
because nowhere in the PDF does it say
and they did reply and told me it sucks down to 100 kilopascals..... 700 TORR
So
now
tell me
is that a weak vacuum? is that a strong vacuum...... to expect torch worked glass to hold and hold well?

and
yes I understand this is not your average beginner topic
but
it has its purposes to learn and learn right so I poke and pound on the internet and
started collecting tools ,glass, and books.
I landed here after 3 days of searching the web for the answer to this question.... can boro be attached to a mason jar.
