Made a UK version and it works great. Not the same, but great anyway :)

Subbed Frit for GB, Custer for BPS and tile 6 for Devon china clay. Added silica to balance formula.

Tests fired with a weird cooling schedule using my broken kiln controller. Dropped to 815, ramped back up to 925 and held for and hour.

Have fun and experiment!
