Blue Ice in Minecraft: Recipe, Cost & Boat Speed

Blue ice is the fastest, slipperiest ice in Minecraft — and the most expensive, costing 9 packed ice (or 81 regular ice) per block. It never melts, it's fully opaque, boats reach a reference top speed of 72.73 m/s on it versus 40 m/s on ice and packed ice (wiki: Blue Ice), and it feeds basalt generators. You can craft it, strip it from the underside of frozen-ocean icebergs with Silk Touch, or buy it from a wandering trader for 6 emeralds. Whether that cost pays off depends on trip length — see Is Blue Ice Worth It? for the worked numbers.

Quick facts

Property	Blue ice
Drops itself?	Only with Silk Touch — any enchanted tool; pickaxe fastest (wiki)
Without Silk Touch	Drops nothing (no water either — see the Silk Touch table)
Melts?	Never (wiki)
Slippery?	The most: friction 0.989 vs 0.98 for ice and packed ice (wiki)
Transparent?	No — fully opaque
Boat speed	72.73 m/s wiki reference top speed (vs 40 m/s) — exactly 72 and 8/11 m/s, rounded (wiki: Boat)
Crafted from	9 packed ice → 1 blue ice (one-way)
Also makes	Basalt (with lava + soul soil); brittle ice with water (upcoming)
Trader price	6 emeralds (wiki)

How to get blue ice

1. Mine it with Silk Touch (cheapest in effort, if you find it)

Blue ice generates on the bottom of icebergs and as large arching structures in frozen ocean biomes; some snowy plains village houses and ancient cities hold piles of it, and rarely an entire iceberg is blue ice (wiki: Blue Ice). Bring a Silk Touch tool — anything enchanted works, a pickaxe mines fastest. Under the icebergs you'll also find packed ice, so one iceberg trip fills both shopping lists.

2. Craft it: 9 packed ice → 1 blue ice

Fill a 3×3 crafting grid with packed ice (wiki: Blue Ice). The full chain from ice: 81 ice → 9 packed ice → 1 blue ice — the wiki states the 81-ice figure directly. That cost is why the "is it worth it" question exists; the worked cases show exact block counts for 100- and 1,000-block roads.

3. Buy from a wandering trader — 6 emeralds per block

Wandering traders occasionally sell blue ice for 6 emeralds (wiki: Blue Ice). Fine for a decorative accent; not a serious route for a 2,000-block highway, and Bedrock's trader-death drop trick (25% + Looting, while you hold an emerald) applies to the blue ice trade too.

What blue ice is used for

• The fastest boat roads in the game. The wiki's Boat page puts boats at a top speed of about 72.73 blocks per second on blue ice — exactly 72 and 8/11, rounded — against 40 blocks/s on ice, packed ice and frosted ice, and 8 blocks/s on water (wiki: Boat, wiki: Blue Ice). In the Nether, a blue-ice highway paired with the 1:8 overworld-to-Nether coordinate ratio works out to an effective 320 m/s of overworld travel (wiki: Ice). What those numbers do and don't promise: Best Ice for Boat Roads.
• Basalt generators. When lava flows into a space above soul soil and next to blue ice, basalt forms (wiki: Blue Ice) — the classic renewable-basalt farm uses exactly one block of blue ice.
• Brittle ice production (Fourth Drop 2026, in testing): water touching a blue ice block horizontally turns into brittle ice (wiki: Fourth Drop 2026).
• Item streams. Like other ice, blue ice speeds up dropped items in water streams; mobs, notably, do not move faster in currents over it (wiki: Blue Ice).
• Opaque, melt-proof building. The deep blue reads well as an accent block, and like packed ice it can't melt near light.

Java vs Bedrock differences

• Break time differs noticeably between editions (the wiki lists different bare-hand times); Silk Touch requirement and drops are the same.
• Historical curiosity: Bedrock's blue ice briefly emitted light in a 1.17 beta — removed before release; Java never had it (wiki: Blue Ice).
• Boat speed figures come from the wiki's Java-side physics documentation; the wiki states both editions' boat handling is scaled to produce the same top speeds (wiki: Boat). The wiki publishes no Bedrock table, but the best community measurement — a speedometer-equipped 2,000-block blue-ice run (r/MCPE) — put Bedrock's blue-ice top speed at about 72.3 blocks/s, right on the wiki figure. Our own timed runs are still pending.

FAQ

Why is blue ice so expensive?

Nine packed ice per block, and each packed ice is nine regular ice — 81 ice total if you craft the whole chain. Nothing in the game discounts it; the price is the design.

Does blue ice melt near torches?

No. Blue ice never melts, at any light level (wiki: Blue Ice).

Is blue ice worth it for a 1,000-block road?

It depends on how often you'll travel it. The per-trip saving is roughly 11 seconds per 1,000 blocks on the reference speeds; the material cost is 9× packed ice. Full math: Is Blue Ice Worth It?

Can you undo blue ice back into packed ice?

No. Like packed ice, blue ice is not a storage block — the recipe only compresses upward (wiki: Blue Ice). ---
