SKC Posted December 5 Posted December 5 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. 3.mp4
cmjlab Posted December 6 Posted December 6 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! 1

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. 1
SKC Posted December 6 Author Posted December 6 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.
Zumber Posted December 6 Posted December 6 I directly dry Strontium nitrate in sunshine for 4 to 5 hours before use.
