A '''block fuse''' is any [[fuse]] that burns through a [[Blockic]] constellation.
A '''block fuse''' is any [[fuse]] that burns through a [[Blockic]] constellation.
This list does not include trivial fuses where a spaceship [[Fly-by deletion|deletes]] or modifies stationary objects, or engineered fuses consisting of parts that can be trivially rearranged to get different speeds.
This fuse consists of a single heavyweight spaceship used to ignite one row of blocks separated by 2-cell gaps, similarly to the [[blinker fuse#c/2 orthogonal|c/2 orthogonal blinker fuse]]. It is useful because it travels at the same speed as the known block puffers such as [[p28 block puffer]], [[pufferfish]] and [[bi-block puffer]] allowing for the construction of arbitrary-length spaceships. Note that Coe ship's side spark can also be used in cleanup.
This [[c/6 orthogonal]] block fuse consists of a [[bulldozer]] used to ignite one row of blocks separated by 2-cell gaps, similarly to the [[blinker fuse#c/6 orthogonal|c/6 orthogonal blinker fuse]].{{EmbedViewer

This 4c/7 block fuse is a cleanfuse which consists of a single pre-beehive used to ignite two rows of blocks separated by 3-cell gaps, similarly to the 2c/3 bi-block fuse.
This 3c/10 orthogonal block fuse consists of a single pi-heptomino used to ignite two rows of blocks separated by 7-cell gaps. It is used in Pi ship 1.
In Grounded Life, there is a simple reburnable fuse based on blocks and a beehive, which evolves into a line-of-six spark. It is the basis of most technology in that rule, and there is a rich and growing toolkit to control it.
