Pyrotechnic Chemistry Forum
We've had a few technical issues with the old Pyrochemistry site – so are in the process of renewing it completely. For those who attended the recent pyrotechnic chemistry course at Grafham – we will have the pdf versions of the presentations available very shortly. Please bear with us.
Буду знать, большое спасибо за помощь в этом вопросе….
