When you unscrew the mason jar, will it be completely full and spill everywhere?

It can drip a bit. On YouTube on the CraftABrew channel there is a video that shows a demonstration. They place a small bowl under the mason jar to catch any excess. Expect the jar to be full, which is a good thing in terms of reducing gas in the headspace of the jar.

Is it possible to use it to decant the trub after boiling the mash? Is it high temperature resistant?

Ely F, This was a gift to my son in law, so here is his answer to your question.: But, yes it collects all the undesirables, he can’t add boiling liquid to it. He’d have to chill the mash to 70-75 degrees. The Catalyst will withstand the temperature from a dishwasher, but if they are asking if they can pour boiling hot wort into it, they should use a wort chiller before adding it to the Catalyst. 16 oz. mason jars are recommended for collecting the trub. After that, 8 oz jars are recommended for collecting yeast if they choose to reuse it for future batches.

How do you clean and sanitize the lid? Do you have to remove that gasket to effectively sanitize it?

The removing the gasket is the easy part, getting the gasket back on while it's slippery from Sanitizer is the harder part. But seriously it's not anywhere as troublesome as trying to clean an old school carboy or sanitizing and using the autosiphon. I just flip the lid upside down with the bung in it, support it so it stays still and pool my sanitizer in it like a shallow bowl.
