Which Ice Doesn't Melt in Minecraft? A Building Guide
Three ice blocks never melt: packed ice, blue ice — and, in the Fourth Drop 2026 test builds, brittle ice and packed ice bricks. Plain ice is the only one that melts, and it does so whenever the block light level next to it rises above 11 (wiki: Ice). Daylight never melts ice — sky light is ignored — so an ice roof under the sun is safe, while one torch beside your ice wall is not. This guide turns that rule into build decisions: which ice for floors, walls and decoration, what survives the Nether, and what the new blocks change.
Version note: Packed ice and blue ice never melting is long-standing behaviour in all released Java and Bedrock versions. Brittle ice and packed ice bricks are test-build content (Java 26.4 Snapshot 5+, Bedrock Preview/Beta 26.70.21+) as of October 21, 2026, and are marked as such throughout.
The melt rules, precisely
| Ice | Melts? | Exact rule |
|---|---|---|
| Ice | Yes | Block light level immediately next to it on any side above 11 → melts into water. Sky light ignored. (wiki: Ice) |
| Packed ice | Never | No light interaction (wiki: Packed Ice) |
| Blue ice | Never | No light interaction (wiki: Blue Ice) |
| Frosted ice | Cracks, then melts | Light-dependent crack stages (internal light > 11 − age); lingers in the dark (wiki: Frosted Ice) |
| Brittle ice (test) | Never | "Does not melt" (wiki: Brittle Ice) |
| Packed ice bricks (test) | Never | "Do not melt when exposed to high light levels" (wiki: Packed Ice Bricks) |
Practical translation for plain ice: torches (light 14) melt ice within two blocks; glowstone, lanterns and lava (15) melt adjacent ice. If you want to keep ice features lit, move the light source two-plus blocks away, put glass between (light passes, but the glass block separates them — note the block light next to the ice is what matters, so distance is the reliable fix), or switch materials.
Choosing your no-melt ice
| Packed ice | Blue ice | Packed ice bricks (test) | |
|---|---|---|---|
| Melts | Never | Never | Never |
| Leaks water when broken | No | No | No |
| Slippery surface? | Yes — entities slide | Yes — most slippery | No — default friction |
| Look | Pale blue, opaque | Deep blue, opaque | Pale blue brick pattern + slab/stairs/wall/chiseled |
| Cost per block | 9 ice, trader 1 emerald, mineable | 9 packed ice, trader 6 emeralds, mineable | 4 packed ice → 4 bricks |
| Collecting | Silk Touch required | Silk Touch required | Any tool — always drops |
| Best for | Ice roads, slippery floors, budget walls | Speed roads, accents, basalt generators | Stairs/slabs/walls, non-slip ice builds |
Building with ice, room by room
Floors. Packed ice is the workhorse: never melts, mob-spawnable, everything slides (fun by design, hazard by accident — put walls up). If your players hate the slide, the bricks set is the first non-slippery ice — but it's test-only until Drop 4 ships. Plain ice floors belong only in dark rooms with no nearby light sources, and remember breaking them floods the room (supported blocks below) (wiki: Packed Ice).
Walls and ceilings. Any no-melt ice works structurally — they're full solid blocks. Plain ice walls are translucent and will melt near interior lighting, so they suit ice-cave aesthetics lit from far away or by sky light. Blue ice reads darkest and richest; packed ice bricks give a tuff-bricks-like 3D pattern with matching stairs and slabs for roofs and trim (wiki: Packed Ice Bricks).
Lighting an ice build. Options that don't melt plain ice: light sources two-plus blocks from any ice face, sky-lit atriums (sunlight is safe), sea lanterns behind packed/blue ice (they never melt anyway), or redstone torches (light 7 — below the threshold). The moment an ice face touches light level 12+, countdown to puddle.
The Nether. The one place plain ice gets interesting: it can't produce water there — broken or melted ice in the Nether simply vanishes (wiki: Ice). That makes plain ice safe to mine in the Nether but pointless as a building material that should stay; packed or blue ice are the Nether-building choices, immune to light and loss. (Ice does not melt spontaneously in the Nether from ambient heat — the wiki documents no temperature-based melting; the danger is light you place near it.)
Frost Walker paths. Not a building material — frosted ice melts back into water on a light-dependent timer. Underground or at night it's stable enough for a crossing; don't build with it (wiki: Frosted Ice).
Design notes that are taste, not fact
These are aesthetic recommendations, clearly separate from the mechanics above: pale packed ice suits snow-theme palettes; blue ice contrasts well with deepslate and blackstone; the bricks' non-slip floor makes icy-themed interiors playable without Boots of Regret. None of this is verifiable mechanics — it's build advice.
FAQ
Does ice melt under glass with sunlight?
No. Sunlight is sky light, and sky light never melts ice (wiki: Ice).
What light level melts ice?
Block light higher than 11 on any side — so anything from light level 12 up. Torches emit 14, glowstone and lanterns 15, sea lanterns 15, redstone torches 7 (safe).
Does packed ice melt in the Nether?
No — and neither does blue ice. Nothing melts them anywhere; the Nether's quirk is that plain ice can't leave water there.
Will the new packed ice bricks melt near my torches?
No — Mojang's changelog states "Does not melt", and the wiki confirms they don't create water when broken either. They're test-build content until the Fourth Drop 2026 ships (official Bedrock changelog). ---
