Gondh katira is pure white and good.

Is it real gond katira or normal bsbool gum? As I have ordered n its not be fluffy while socking in water instead disolve it?

This is gond katira.. soak little amount in water and leave it over night.. in the morning it gets fluffy and ready to eat

Does is dissolve or transform into gel on soaking in water?

It does not Dissolve. It gets swollen up by soaking in water and creates a slippery gel. It usually provides relief from heat strokes and irritable bowels. for using it is advisable to crush big lumps in to small pieces. NO need to grind or powder.
