How to fine Oranage Slime balls for Tinker's weapons

Im trying to make magma slime but there doesn't seem to be any information on how to find orange slimeballs. Killing magma cubes hasn't seemed to work.

 

slime islands in the nether floating on the lava surface you get it from around the pool in the center and from the trees that grow there

 

So are they up high or down low. Didn't really catch that part.

 

on the lava surface what is around y20ish i think

 

Wouldn't suggest going for this until you have a pyrotheum pendant from Bontania though. The lava pool in the middle of the island spawns Magma slimes, sometimes in very large quantities.

Should take a stack or 4 of cobble and fill the center pool. won't stop the spawns but it does seem to slow them.
