well, you could also go the cheaty way, since you don't have GregTech.
go to a dessert, and collect some cinderpearl flowers, as they drop blaze powder.
then get a minimum stone, and put the stone and 2 blaze powder in a crafting grid to get a blaze rod, you can then macerate/pulverize/grind it to get about 4-5 blaze powder from that 1 blaze rod, then repeat the minium stone part and keep repeating this all till you've the amount of blaze rods you wanted. it's a bit cheaty, but minecraft sure can get annoying from time to time if you're trying to find a certain resource
