When people talk about GYPSUM as being a clay breaker, will it be ok
to use the type of bags of plaster that they sell at builders
merchants (it does say on the side of the bag contains gypsum) the
bag i looked at said finnish plaster (I think) or does it have to be
gypsum (plaster of paris etc)?

I'm fairly sure that gypsum is a major ingredient in the plaster
lining boards used in modern housing, so assume that the same would
apply to a bag of powder called "finnish plaster" (or could it be
"finish plaster)?????? Wouldn't it be possible in the UK to buy bags
of gypsum at garden centres and know you have the right thing for
garden use? If not, you may need to look closely at the bags of
"Finnish Plaster" to see if there is an ingredient list on the bag.

used plaster board is being recycled to salvage gypsum in it for
agricultural use.
