For a practical ghast-resistant shelter or portal enclosure, use cobblestone, stone, deepslate, or nether bricks. Community Minecraft guides recommend these materials against ghast explosions. Glass needs a qualification: one guide says full glass blocks survive direct fireball hits, but nearby explosions can break thinner glass panes. The available sources do not establish a universal blast-resistance number that guarantees safety across every block, edition, and game release.
Which blocks are practical choices?
Community-maintained Minecraft guides recommend these materials for structures exposed to ghast fireballs:

- Cobblestone
- Stone
- Deepslate
- Nether bricks
These are practical recommendations, not an exhaustive list of every block that can withstand a hit. Ghast fireballs can damage weaker blocks, so a shelter or portal enclosure made from the listed materials is a safer choice than relying on a block without supporting guidance. The Minecraft Wiki’s blast-resistance values module gives some block values, but the available evidence does not turn them into a guaranteed rule for all blocks and releases.
Can ghasts break glass?
Distinguish a full glass block from a glass pane. A community defense guide says glass blocks survive direct ghast fireball hits, while panes can shatter from nearby explosions. That is the guide’s advice, not an official, version-independent guarantee. If you want visibility while building a robust enclosure, the guide supports glass blocks more clearly than panes. Read the community defense tutorial.

Is there a blast-resistance number that guarantees safety?
Do not rely on a single cutoff as a universal guarantee. The Minecraft Wiki values module lists cobblestone at blast resistance 6, basalt at 4.2, cobweb at 4, and furnaces at 3.5; it says the values come from game code. Those figures describe blocks, but the available discussion does not establish a definitive threshold for whether a ghast fireball will break a block in every edition and release. See the blast-resistance values module.
The discussion illustrates the uncertainty: one contributor reported a furnace with resistance 3.5 surviving a ghast fireball. That is an individual observation, not a controlled test across versions, so it should not be treated as proof that every block at or above 3.5 is safe. The related Minecraft Wiki discussion does not settle a universal cutoff.
What this means when building
- For a straightforward shelter or portal surround, choose cobblestone, stone, deepslate, or nether bricks.
- For a see-through section, prefer full glass blocks over panes based on the cited guide’s distinction.
- Treat blast-resistance values as useful block data, not a cross-version guarantee of ghast-fireball behavior.
The cited sources are community-maintained and are not pinned to a specific current Minecraft version. They support practical material choices, but not a complete current list for every edition or a precise threshold that applies everywhere.
