I found this -
"White cement is a specialised product requiring a high degree of quality control at all stages of production. lts use is found in the manufacture of terrazo tiles, precast facade finishes and for other decorative purposes. White cement is not a conventional cement and is normally used for its appearance and low maintenance requirement. It has, however, all the strength and properties of'ordinary Portland cement and is frequently used for construction purposes. "

I would think it would be a bit too strong for normal papier mache work.  What you need is something like groundchalk, calcium carbonate.

Thanks Sue and David,

I am trying to find ground chalk here but the problem here in Singapore is that many store helpers are nor familiar with the English terms......might have to use some more explanatory body language heeeee. I came across something called putty (ready mix joint compound with something else also ,don't remember what)I think it should be fine ..........Any information on this?

Hi, I have just bought some "drywall compound " in Australia and a similiar product here is MultiPurpose Joint Cement, made by Bostic. It is used to join plaster board to walls, as already stated.
Chalk is also known as whiting here in Aus, and is cheap as dirt if bought from a ceramic supply outlet or pottery supply outlet.
I hope this may be of some help.

The other names for chalk are whiting and calcium carbonate (which is its chemical name).  If you only need a small amount and have access to those children's chalk sticks, just grind some up to a fine powder and use that.

Another source for chalk/whiting/calcium carbonate is a place that sells clay and materials for pottery.  Around here, it's about $1/pound/.45kg.

Payal, is there a name of that product in English?  Does it have an ingredient list?  If the name is in English, you might be able to determine the ingredients by googling '[product name] MSDS'.  An MSDS is a Material Safety and Handling Sheet, and most are available online unless they are so non-toxic they are suitable for small children.  It may require some searching.
