How To Make Block Ice 2023 All Top Of Options For You

Generating ice can be a difficult task for various individuals. One of the most popular ways how to make block ice is by using a cardboard box, a pan, and a little salt. Despite this simple process, it takes time and water to generate enough ice to last a month. In general, the warmer the ice melts, the more bacteria will grow.

Block ice lasts much longer than regular because it doesn’t have any liquid in it. With a few simple steps, you can enjoy a nice block of ice. Let’s start to learn those ways in this post!

Why Use Block Ice?

Why Use Block Ice

Larger blocks last longer and melt faster than cubed. A few large blocks in your cooler can keep you cold for many days.

The nine large blocks pictured above were covered with sawdust and left outside. One month later, there was still ice!

Although it looks like a rock, the ice is one month old.

Block ice can be made at home, which can help you save money. Also, if you have block ice in a bottle (as we will show you), you can drink the melted ice during your trip.

Clear blocks of ice can last longer than regular if you put in the effort and time. They can also be used to make cocktails, spirits, or ice carving.

Cooler Ice Blocks vs. Crushed Ice

Now we are familiar with the main advantages of the block. Let’s now see if block is better than crushed or cubes.

Crushed vs. Blocks are excellent for the long-term storage of perishable foods because it retains longer.

It is perfect for increasing the life span of fish, meats, and other foods. It is a natural choice. There is one drawback. While crushed melts faster than block, it also cools food faster. Remember that crushed is larger than its volume to absorb heat more easily from the cooling process.

It is the same quality that causes crushed to melt quickly, and it also causes it to cool down so fast. On the other hand, block ice has a low volume to surface area ratio. It takes time for block ice to absorb all heat from the cooling process.

Are our Ice Blocks Better for Coolers?

This problem can be solved by pre-chilling the food before it is put in the cooler.

While you’re at the same time, pre-chill your cooler. Place the food in the freezer. Let it sit there for 6-12 hours before you travel.

The cooler needs to be pre-chilled for 12 hours before you go. This will ensure that you don’t freeze food before packing your cooler. It’s important to freeze it, which is why the block is great.

You can also mix crushed and block ice in your cooler. The block can be placed at the bottom and the crushed ice on the top. The crushed chills the food while the block keeps the temperatures steady. It wouldn’t hurt to add a few quality packs.

A windshield sunshade can be purchased to cover your cooler, mainly if it’s being used for fish or game meat. This will keep the cooler cool for longer.

This method requires some sacrifices in terms of the cooler’s capacity. You’ll have less food because you’re putting so much space into your ice.

Although some clever packing techniques (layering food between layers of ice) can help, it is not enough.

Either get a big cooler or make space concessions. You can also pre-chill your food to avoid all the hassle.

How To Make Clear Block – DIY Blocks

How To Make Clear Block Ice – DIY Ice Blocks

DIY Molds: Bottles, Milk Jugs, Buckets, Ice Cream Containers, etc

Because they are primarily sealed containers, I would classify them all in the same category. They are tall and narrow and don’t allow water to breathe.

Plastic Bottles

Bottles are one example. For making block molds, bottles are an excellent choice. Because the ice is not removed from the bottle, you can place it in the cooler.

If you tightly cap the bottle, water will not get everywhere in your cooler if it melts.

This is great for dry foods that you don’t want to get soggy. After the water has melted, you can use it to make drinking water. Your water bottles can double as cooling to save space. Bottles are generally made from plastic or glass.

As the water freezes, the plastic bottles will begin to bow. If you are into aesthetics, this will result in a hideous bottle.

It would help if you also were careful not to fill your bottle too full. This could cause the plastic to crack and allow any frozen water to leak out.

Please don’t fill the bottle up to its maximum capacity. Allow the water to air for between 1 and 2 inches.

If the bottle is made from glass, it will be the same. The glass will not have the ability to bow, and it will crack or break completely, spilling any unfrozen water.

This is also true for milk which is glorified bottles.

Plastic Containers

Size is essential when it comes to containers such as an ice cream bucket. First, determine how big you want your blocks, and then decide if a container that size will fit in your freezer.

As I have learned from painful experiences, your freezer can be a real hindrance to this process.

One time I wanted large blocks, so I bought a bucket from the grocery store. I filled it with water and brought it to the freezer. But, it wouldn’t fit.

So I went back to the shop to buy a smaller one that would fit better in my freezer.

It did. The good news is, it did. However, I had to take out most of the items in the freezer and squeeze what was left in various corners and crannies.

However, that’s not the end. Another part is that I filled the bucket with too much water, and it cracked and bowed.

Unfrozen water escaped and formed a 1-inch thick layer of ice at the bottom of the freezer. The plastic also expanded so much due to the freezing inside that it became stuck against the freezer walls. It was the most challenging project I have ever had to complete.

This little story brings me to the next tip that I have learned over the years: Don’t fill up your buckets, or even halfway, if you want to freeze correctly and quickly.

It is essential that the freezes in less than one month. Block can take a while to freeze, I’m sure.

My trick was to add a little water to the container, then let it freeze. Then, I added more water. This makes the freeze faster and doesn’t shrink as much, morphing the container along the way.

It is surprisingly effective for both plastic and glass bottles.


Metal is the best material to freeze block. It won’t stick to the metal containers, so it is easy to take it out of its mold.

Metal containers can be challenging to find, and I have yet to see a complete metal bottle. The other options include rubber, glass, or plastic.

Because glass containers are fragile, they can be dangerous. Glass containers can crack or shatter easily due to the expansion of water as it freezes.

I recommend that you use glass with care. You can also freeze a small amount of water at a given time, adding more as it freezes.

It’s not as easy to find suitable rubber containers as finding one made of metal. However, you might find one made from silicone, which I will discuss in the next section.

A rubber bottle is something I have never heard of.

Ready-Made Block Ice Molds

Ready-Made Block Ice Molds

There is one particular problem in the market: there aren’t many ready-made ice blocks molds, especially large ones.

Ice cube molds and trays are readily available, but blocks appear to be a DIY project. This is an excellent opportunity for entrepreneurs, and we hope to see products on the market soon.

You can use hacks to make blocks almost as easy as buying a ready-made mold. Besides that, our list has more tips for making ice without a tray.

Silicone Bread Loaf Pan

This is our favorite hack. Silicone is great for making block mold material, as the ice doesn’t stick. Regular blocks can also be made by using the shape of a bread loaf pan.

It isn’t easy to lift the pan once it’s full, as the water can easily splash.

It’s possible to get around this problem by placing it in the freezer and then pouring water into it. Make sure to pour a little at a time, then let it freeze and add more.

Rectangular Food Pans

These can also be used to make regular block. The instructions for using them are the same as for the silicone bread loaf mold.

Many other options are available, such as hospital plastic bath basins and cake pans, Tupperware containers, and even a PVC tube cut in half.

The only limit is your imagination, but most of the tips and tricks above still apply.


Can you craft ice blocks?

How do you make soft ice?

Soft ice is also known as a nugget or ice. This is due to its soft texture and chewy texture. You can make soft ice at home by freezing club soda or carbonated waters in a tray. Next, use your preferred method to crush the cubes, such as in a blender or with a muddler. Enjoy!

Where can I find snow blocks?

You can now find snow block items in the chests of snowy village homes.


Having made cubes, you may find yourself wondering why they are necessary. The truth is, cubes are an economical way to stay cool on hot days. They’re easy to pack with for hikes, games, and picnics. Unless you’re traveling into space or exploring the depths of the ocean, having ice on hand will be indispensable.
