Could this be a copy of a Yaozhou celadon, Northern Song Dynasty AD 960 - 1127, You say white glaze but the pictures look like a light green color.

This is white porcelain. At least in contemporary terms. Yaozhou glazes are a darker greenish color, but you are very close respective the era!

Song white wares were not really white as we see it on Ming or Qing dynasty porcelain, especially the Dehua wares.
In our current usage those white items would not have been really white. Either they had a yellowish or a light gray color tone.
They could not produce real white glazes then as they had to rely on materials that could be mined in nature, in those times.
BTW. the greenish tint is only present in places where the glaze was running or especially thick as in crevices.
