100 grams of extra fine Fe2O3 thermite, producing white hot, liquid, Iron metal.
500 grams of Fe2O3 thermite reacted in a heavy cast Iron skillet. A failed attempt to melt through the skillet, the skillet conducted the heat into the wooden planks supporting it, catching them on fire. Liquid Iron fused itself onto the skillet.

2000 grams of Fe2O3 thermite, filling a large coffee can, reacts on top of a ¼ inch thick, steel, I-Beam. The resulting reaction is so intensely hot that it melts its container and the steel beam, spilling vast amounts of molten Iron and Al2O3 everywhere.

200 grams of Fe2O3thermite made with fine-grain (3.2 micron) aluminum powder reacts more quickly due to the smaller particle size.

200 grams of Fe3O4 thermite reacting inside galvanized steel pipe on cast Iron skillet. Due to the heat of the reaction, the Zinc coating on pipe is vaporized and converted into fluffy white puffs of Zinc Oxide . The reaction leaves the white-hot pipe thoroughly welded to the skillet and covered with ZnO.

4000 grams of Fe3O4 thermite, filling a large, 10-inch diameter flower pot, reacts on top of an old hard drive. The molten metal produced by the reaction melts through the hard drive casing and platters and totally destroys the internal electronics. Sadly, no video was captured of this extremely impressive reaction.

100 gram, blindingly bright, CuO Thermite reaction glowing white hot and partially melting the coffee can.
Using extra fine Copper Oxide powder, the 100 gram thermite reaction proceeds very violently and explosively, vaporizing much of the remains, starting grass fires, and pushing observers back with a shockwave.
 
100 grams of CuO thermite made using very fine CuO powder. Once ignited, the thermite mixture reacts extremely quickly and energetically, expelling the vast majority of the products into the air.

This 100 gram thermite reaction proceeds very slowly, steadily consuming the thermite mixture. The reaction failed to reduce the white TiO2 to Titanium metal, but instead reduced the TiO2 to a black compound which is likely to be Ti3O5.
100 grams of KClO3-boosted TiO2 thermite react after being ignited with Magnesium Ribbon. Thermite reaction successfully yields several grams of Titanium metal as a product.  
530 grams of KClO3-boosted TiO2 thermite using a TiO2 : Al : KClO3 : CaF2 ratio of 100 : 75 : 50 : 40. Reaction produces several large blobs of Titanium metal.

200 grams of thermite made using a mixture of Fe2O3, Cu2O, and Cr2O3 thermites in a ratio of 7 : 8 : 5 by weight. As a result of the reaction, a copper-colored metal alloy was formed containing Iron, Copper, and Chromium metals in a theoretical ratio of 3 : 5 : 2 by weight. A small amount of Cryolite flux was utilized.
200 grams of Manganese(III) Oxide thermite (placed on bottom of container) with about 125 grams of Iron(II, III) Oxide thermite on top. The Fe3O4 thermite was ignited which, in turn, ignited the Mn2O3 thermite. Excellent slag-metal separation leaving a large blob of ferromanganese alloy metal. No flux used.

 

 

220 grams of thermite made with a ratio of 5 : 3 : 2 between stoichiometric mixtures of NiO, Fe3O4, and Mn2O3 thermites respectively. Additionally, 30 grams of Cryolite flux was added bringing the total mass of the mixture to 250 grams. The reaction proceeded somewhat slowly once ignited using Potassium Chlorate, sugar, and Magnesium Ribbon, but burned quite hot and left a large chunk of alloyed metal behind.
