My 4 pallets of Liberty Bricks arrived yesterday. (I still don't know if they are bricks or blocks since there was no brand markings either on the bricks themselves or the individual packages or the pallets. Here's what they look like: The guy delivering them got his pallet jack stuck on my driveway, (got to get around to paving it), and long story short, I had to get a chain from the neighbor and he pulled the pallet jack back onto the road with the truck. In doing so, he tipped over the one pallet of bricks. He was very apologetic and stacked all the packs and I just used the broken packs to fill my wood box. That was the only adventure, now onto the review. The bricks are very non-descript and have no markings and just look like compressed particle board or plywood. The shrink wrap packaging is very skimpy so that if you try to carry 2 packs and use one hand to open the door, the pressure on the one spot of the pack with the other pack on top will often break open the shrink wrap. I finally put them in those mail cartons you're not supposed to have to carry 2 at a time. There are 10 bricks in a pack and the delivery guy said they are 3 pound bricks and the Bios are 2 pounds. Every row in the pallet had 1 bag of 8, I assume to fit the pallet. He also said the guy that developed Biobricks sold the Liberty Brick guy the machine to make them, so they are made on the same machine. He also said that his company, BT Enterprises, only made $20 a pallet. (@$255 a pallet) Here's some of the packs that fell off the pallet: Poor guy had to stack them: I brought 2 pallets worth inside yesterday, it took about 2 hours a pallet: The first clear advantage is in stacking and space taken up. If they truly are equivalent to a cord and a half, then I was able to store 3 months worth of wood inside the house in the same amount of space as usually 2 weeks worth of cordwood takes up. On the downside, the bricks have none of the ambience of cordwood, they smell like you just cut a pice of plywood with your circular saw. I was impressed with how well the bricks held together, no brick broke apart even under the weight of the pallet tipping over. On to the burning: I was very impressed! I started a fire at 9:00pm using 6 bricks and simply put 1 brick in the stove (Quad 5100 insert) and put a Super Cedar firestarter, (thanks for the free sample guys!) and then built a tee pee over that with 2 bricks on either side and one directly over the Super Cedar. The fire caught with no further meddling and temp rose nice and steady. Once the bricks were fully engaged, I started damping it down and I was able to damp it down all the way and still maintain 600 degrees on the stove top. 5 hours later I added 2 bricks and 3 hours later 2 more and the stove was still on at 9:00am. (We have a newborn and it was my night, so perfect for watching the bricks burn overnight!) It was in the low 50's, so just a low fire to take the chill off for the newborn and wifee. It averaged a brick an hour, I used 12 bricks from 9:00pm to 9:00am. I'll post more as I keep burning, but so far they burn great and it is great knowing how much wood I have right in the house, no worries about all this rain on the East Coast, I can now burn until Christmas!
