The Blaze Burner can be made blue (i.e. "high heat") by giving him a Fuel Bucket. But to "properly" automate the Burner, it's recommended to give him a Straw, which changes his appearance and allows him to accept liquid fuel via Pump/Fluid Pipe.

Bug 1: This doesn't work; Fuel by pump results in the same "normal heating" state as Charcoal. The Burner lights up but does not turn blue!

Bug 2: Right-clicking on a Straw-using Burner in the "normal heating" state with a Fuel Bucket crashes the client.

I haven't tested whether a quiescent ("off") Burner will also crash the client if right-clicked with a Fuel bucket.

Both of these issues are on crafts and additions' behalf, not ours.

1. Fabric liquid burning does not yet support superheating
2. Right clicking any blaze burner with a straw crashes the client, just dont do it. This should be patched in the next crafts and additions release, but we do not know if that will also include 1.18.2.

This appears to be fixed in Create Astral 2.0.4 because Create Crafts & Additions was updated

If it’s fixed I’m going to close this issue as such
