Couple of little bottles

Two small bottles. Picked them up because of the unusual T shaped mould scar on the base.
Anyone know anything about them?
The seller was selling her late father's stuff, which included the usual ink and pop bottles.
One blue, the other a greenish-cream. White earthenware. Unglazed inside, so too porous for liquid.  
Very clean inside, so despite the crazing on the white one, they may not be very old.
