Descriptions:
Lava glazes have one variable that changes everything — the ratio between your R2O and RO fluxes. In this video I walk through real test tiles from my workshops in Bali and Portugal, showing how shifting this single ratio takes a glaze from stiff and under-melted all the way to richly bubbling lava and dramatic crawls.
If you’ve ever wondered why your lava glaze looks flat, or why the same recipe fires differently every time — this is why.
