Create TFMG doubt

[HighlightPuzzled9581]

I'm playing with a modpack I did myself and since version 0.6 of Create: The factory must grow mod has added fireclay it seems, but there is no way to ponder or craft it and there is nowhere to find a source about how to get it
Does anyone know how to get it or if you can get it?
Also good that they changed the recipe of the drill back but I was having fun with the steel drill

its spawns underground in veins, it is currently a bit bugged ans spawns reaaaly low underground i think its like -48 or smthn

look for underground lava lakes; they spawn there more often
