Sparkler #10

The composition burns very fast and explosively if one doesn't pay extreme attention towards the diameter of the sparkler. It is found that if the comp is thinner than 1.8 mm then the propagation stops. If the diameter is more than 2.0 mm the burning is too fast, sending sparks all the way down to the ground. Another severe problem is keeping the ingredients mixed in the suspention. The Ti has a very strong tendensy of ending up in the bottom of the test tube, making a plug. Another problem is that after the first dipping and subsequent drying, the second (and last) dipping has to be performed very, very fast or else the first dipping is spoiled, hence the bound dextrin is redisolved. Using coarser perchlorate, finer titanium and making the dipping mixture thicker (by using less solvent) may solve these problems.

Sparkler #11

The aluminum is probably supposed to be atomized, but experimentation is required.

Potassium nitrate.................................14
Sulfur............................................3
Charcoal..........................................3
Aluminum..........................................2
Binder............................................qs

Sparkler #12
Guar gum comes from the seeds of the legume Cyanopsis Psoralioides. It should be possible to substitue red gum.

Potassium perchlorate.............................40
Mixed titanium fines..............................40
Dextrin...........................................18
Propyl guar.......................................2

Sparkler #13
Mix the composition with a 10% dextrin solution in water, and dip iron wire or wood in the moist compositon. Adding 500 parts strontium nitrate will produce a red color, adding 60 parts barium nitrate will produce a green color.
