Last Diwali humidity was at its best (92%+) in West Bengal, India. Making Strontium based formulation was not a good idea. But still I made a few fountains and had to preserve them in my living room and switch on the air conditioner at 22degree. Now this was the result. I still feel part of the colour had faded away or it might be due to grade of SrNO3 I could obtain. The colour may have been more deeper I think. Should I use lab grade SrNO3 for deeper red.

What's wrong with that one?  In all seriousness I thought it was a nice red with metal sparks, and a most impressive height.  The red didn't look orange at all to me, perhaps one of your fuels lightened up the red a bit, but it could have been the camera too. 

I have seen darker amd lighter red variations between batches of strontium nitrate that I've used in the past, amd ruled out the other components as culprits.  I even had one with a orangish yellowish to it.  

I liked it!

The colour might be faded due to other ingredients which you have used in composition? Like due to excess use of 999/666 aluminium fuel and lower chlorine donor percentage? It's very hard to tell without knowing composition details.

Can you mention other ingredients used in this composition?

I prefer to dry strontium nitrate first before making any strontium base composition or I postpone my work if weather is an issue.

Lab grade strontium prices are double  or too much.

You might give a try again when weather is good but I am sure colour faded due to excess fuel like aluminium.

cmjlab & zumber both of you are appreciated.

Zumber how you dry SrNO3? Under the Sun or use induction oven. As you have diagonosed 999 had carried away some colour. Well I have to compromise colour or height either way.

I directly dry Strontium nitrate in sunshine for 4 to 5 hours before use.
