B1 mix (batch 1, bake 1)
The idea was to create a molecular mixture or to make a molecular complex.
Not entirely succesfull. I will not publish the idea behind it yet.
The content by weight:
KNO3 - 400g
saccharose - 225.6g
Fe2O3 (TD202 type) - 10g
dextrose (D-glucose) - teaspoon (2-3g)
<0.5g other inert material ~300ml solvent water preparation method undisclosed for now, still improving it. I processed the sugar in two batches by accident anyway. The resultant solid material is suspected to be microporous, the resulting burnspeed in open air is about 1-2 inches per second at most, 1cm/s the least for a wet 'stone'. After careful observation I saw long, microscopic crystals of KNO3, this is the result of quick drying process (QDP). QDP also requires equal heat distribution and high, controlled temperature. Under certain conditions the surface area of the KNO3 will be the highest possible.
Not useable as such as it is rock solid because it hardened and dried as I was preparing it. I was able to stir it and model it, but when removed from the soutce of heat the material solidified and dried. It was possible to crumble the material when hot, but as it is cold and solid now, it is very hard to crush it. * about 10-15g of crushed B1 spread in lenght of 7cm burned on thin paper (slightly weaker than office paper ~70g/m2) in about 0.5s generating large plum of smoke and leaving the paper INTACT. Well the paper catched smoldering on few places after the B1 burned out, but not under where the B1 was, but all over. * I'm keeping the 'stones' of B1 fuel dry, when I tried to light up one of 8mm in size (0.3") it burns so fast you will not have time to retract your hand as it flies away. Waiting for my camera to return home. * to further decrease viscosity of the molten mix - add sulphur. Plasticity of the heated mix dramatically improved from hard marmelade like to strawberry jelly jam like. So soft it could be injection molded. Burn rates are also higher and the tested strands became airborne soon after igniting. Melting point of sulphur is 115°C and it does not dissolve in the sugar, therefore we can expect the mix to melt in low temperatures.
* the flame from added sulphur is not as straight and jet-like like from pure mix. The sulphur tainted B1 has sideflames, like if more rocket engines of different angles were burning there. [note: not all mixes with sulphur did that, but all burned with less dust smoke (Fe2O3) and more flame]
