I normally use two pairs of tongs, especially for bronze. One to lift the crucible by the neck, and a second to support it from the middle to help tip it for pouring and decrease the stress on the neck.

Cut out the main pieces of my crucible lifting tongs. Put a nice angle on the parts that grab so they come pretty well centered.

Tried welding them and absolutely nothing stuck! Granted I don't have a nice welder, it's a Horrible Fright flux core MIG with min/max voltage setting, but still.....

I was kinda wondering by all the sparks throwing off by the angle grinder if they might be carbon steel.

Infrared pyrometer, thermocouple ?

I kick off.

I use a type S (K is too unstable and not high temperature resistant) thermocouple sheathed in alumina but can only measure swirling air/ gas temperature around the crucible. This TC is very durable. I have no means of measuring metal temperature as the couple itself dissolves in the metal (when immersed without sheathing) or the sheathing gets wetted and when pulling it, the wetted sheathing...

My furnace bore is roughly 8 inches with a height of 11 inches.

The Morgan salamander seems to be the gold standard for crucibles. 130 bucks for an A10 though. The A6 is only 60 which is a little better. I've heard several mentions of the legend budget crucibles on here. They are only 30 bucks. Obviously the...
