Dear Narsimhan ji, You friend Sayyad bhai has forwarded me same proposal this morning I have responded him here is the same for your reference.

Dear sir thank you for the proposal, Our criteria for such material is :- Matchstick should catch fire at any distance above the material for example 1" or 2" etc what ever it may be. Without touching or scratching matchstick on material. If it fits in our criteria then we can deal.
