I may be
able to get the clay/sand for free

Bring a spade and trailer to my place - you can have all the clay you
like

Thank you! But you know what... I've tried "puddling" as I undestand
it's called - jumping in clay in wellies to mix in sand and much as I
feel I want the "back to caveman" experience, I feel spending about 50
quid to have 150Kg delivered is worth it...

(I'm told that there's a local quarry throws tonness of some natural 80%
silica content clay at the brick industry which I can get for asking
for it though)
