Introduction to Ice-Lantern making

Start here for ice lantern techniques ranging from simple to elaborate.

Making beautiful ice lanterns doesn't have to be difficult or expensive.   Scroll to the bottom of this page for summaries and links to methods you can use without special equipment -- or for more advanced techniques.

ornaments made in silicone
baking molds.

 I started making ice lanterns during the winter of 2013-2014 and have been adding to my repertoire of designs each season since then. Join me in the next blog posts for a tour of the methods for freezing and decorating ice luminaries of several different varieties.

We began with the simplest of the commercial
ice lantern molds, from Arctic Ice Lanterns, 
and for our first season, we just made and 
illuminated long rows of them.

There's a book!

Since  I started this blog, a great resource has become available for people who want to make ice luminaries or just to understand how it is done.  Jen Hedberg's book offers beautifully-illustrated instructions for projects ranging from basic to elaborate.  

Ice Luminary Magic is available through the Wintercraft website and at many locations in cold-winter areas.   

Our inspiration for making ice lanterns was Jen's display of luminaries more than a decade ago at the Loppet winter festival in Minneapolis, and we learned much of what we know about making them from her.  I started this blog especially to offer some shortcuts and beginner information, but if you want to go beyond that -- or just to understand more of the practical science behind making ice lanterns -- get yourself a copy of the book.

Basic principles for most ice lanterns

Ice freezes in a mold along the walls, leaving a liquid core.  The last surface to freeze is where the mold contacts the ground or certain other objects.  This makes it possible to freeze ice in a mold, pour out the liquid water from the core through the unfrozen ground-contact area, and have a finished ice luminary.  The main problem with this method is that the liquid core expands as the freezing process continues, so if you wait too long, the expansion can break the mold or "explode" the ice lantern.

It isn't necessary to use two nested buckets with water in between them, although that method is also workable and eliminates most mold breakage.  It doesn't produce as nice an ice lantern, however, and getting the two buckets to nest properly is tricky.


Freezing begins along the walls in two
versions of a basic ice lantern.  The
bottom tends to freeze last, especially
if there is an indentation in the mold there.
That makes the simplest version -- seen on
the right side -- possible.  The picture on
the left shows a common, but more
complicated, way to make an
ice luminary.

The same principle works for making globe ice lanterns.  A balloon filled with water will freeze from the outside toward the inside, with a thin or unfrozen area where it sits on the ground.  Break the balloon, and the water will pour out of the core, leaving a hollow that can hold a candle or other light source.

Balloons for making ice lanterns.
These are from Wintercraft and
are extra-strong to hold their shape
when filled with water.  Ordinary
balloons can also be used, but
they generally need support from
a bowl or other container.

Many other shapes can be frozen, using ice-cube trays, candy molds, silicone muffin pans, funnels, shot-glass molds, and other objects.  If two ice objects are slightly moist, they will weld together in the cold, allowing the production of complex designs and shapes.

Freezing ice appliques to decorate
ice lanterns.  Many shapes are
sold for making muffins, soap,
ice, and candies. Silicone
trays are the easiest to use.

Ice lanterns and decorations can be
combined in many ways, "welding"
the pieces together with cold water.

Look here for information on ice appliques and decorating techniques.

At very cold temperatures, stencils can be used to decorate ice surfaces with quick-freezing water.


Stenciling on ice lanterns is an
advanced technique that
requires very cold
conditions.
Click here for more information on using stencils on ice lanterns.

Each entry in the blog describes a different technique, starting with the easiest and progressing to more complicated ones.  I have linked to many of the individual entries from this introduction, and if you are looking at the web version, you will find the pages listed in the right sidebar.

"Bucket" ice lanterns:

"Bucket" ice lanterns:  many different containers will produce a serviceable ice lantern, but there are a few shapes to avoid.  Nothing should interfere with the ice sliding out of the container, and for the single-bucket technique, it helps to have a bottom that is indented.

Good and bad shapes for making
single-bucket ice lanterns.
Here is a very simple little bucket
that can be used to freeze a small
ice lantern.  Its wall slopes outward,
and it can be filled to below the ridge.
There is no ridge protruding inward
to interfere with unmolding.
A slight indentation in the bottom
delays freezing until last, so that the
water in the core can usually just be
poured out through an opening there.
If is does freeze over, the ice will
usually be thin enough to just
break through easily.

You can use containers that you have around home, but there are some molds that are particularly easy.  

The Arctic Ice Lantern mold is a
commercial product that produces
a very nice ice lantern with six sides,
but the mold is liable to crack if it
is left to freeze for too long.
Read about the Arctic Ice Lantern here.

We have a Flickr album here with many more photos of Arctic Ice Lanterns.

One commercial product that comes in a very easy mold for making ice lanterns is the bulk package of Nonni's Chocolate Hazelnut biscotti.

Attention:  this is the very easiest, most foolproof, least messy way to make an ice lantern, and you get to eat biscotti.  If you want to make ice luminaries with kids, it's a great way to start.

This plastic bucket of 25 biscotti is
the easiest, most crack-resistant,
prettiest simple ice lantern mold
that we have found so far.

Globe ice lanterns

The other major class of ice lanterns is ice globes.  They can be made with fairly thin walls, like goldfish bowls, or they can be frozen nearly all the way through, with a very small cavity for a candle.  Wintercraft's balloons are particularly resistant to breaking and can be used to make large ice globes.

We make various kinds of globe ice lanterns, but most of them are in the fishbowl shape.


An ice globe made in an ordinary balloon
in a bowl, with a fairly thin wall, and a
"goldfish bowl" shape.



This globe was made using Wintercraft's
preferred method, producing a small cavity
for the candle, and very thick walls.
Rather than turning the globe over
after emptying the water from the core,
I drilled a chimney down into it (and
added a protective cylinder above),
leaving a small cavity for the candle.

This fishbowl-style ice globe
sits on a base
of Arctic Ice Lanterns and is
decorated with small ice cubes.
A fishbowl really should have fish in it!  But until I found some ice trays for making fish, and realized that they could easily be welded to the inner surface of a large ice globe, I hadn't tried this very entertaining way of making an ice lantern that's just as fun by day as by night.

Special shapes for ice lanterns and other ice forms include flames and teardrops, hanging drops, and funnels. Look through the other posts for a variety of ideas.

Many unusual shapes can be made by constraining a balloon inside some sort of container.  Read about how to soften ordinary shapes this way and to make entirely different constrained-balloon shapes here.

made by using constrained balloons.

A special case of an ice globe is one that is made in a "punch balloon."  It produces a shape that is particularly good for making bases for other ice lanterns and for stacking ice globes to make a "snowman."

When set on the ground and held up by
the cord -- with air blown into it to make
a flat surface on one end and the knot
end being flattened by the ground
underneath, it makes a thick, sturdy
globe shape that stacks well.
The punch balloon globes have
just the right amount of
flattening to look like
rolled snowballs

Making a snowman-shaped "iceman" is demonstrated here.


Another variation on the classic snowman is a tiny ice figure that can be produced in a home freezer.

The "Arare" or "hobnail hailstone" ice lantern

Two strains of decoration for cookware/glassware draw on icy precipitation for their inspiration -- and those were on my mind when I started making ice lanterns that resemble the Japanese Arare metal teapots or the Bohemian/American hobnail hailstone glassware.  It's an uncomplicated but very time-consuming technique that makes a beautiful luminary.  Read about it here.

The "Cut Glass" ice lantern

An easier way to add texture to an
ice lantern is to wrap a flexible
mat with a pattern inside a mold
when freezing it.  See how to make
the "cut glass" luminary here.

Cookie Cutter Ice Windows

Cookie cutters can be used to make ice
windows for daytime displays or to set
up in squares with a central candle as
luminaries.  Here's how.

More ideas for decorating ice lanterns

You can freeze objects and dyes into ice lanterns, but water tends to purify itself as it freezes, pushing added colors and items out of the way.  

Read about freezing things into ice lanterns here.  Some very beautiful ice luminaries are made with flowers inside them, but I find them difficult to produce and have not continued to work on them.

Although freezing a whole ice lantern with added coloring tends to produce a clear luminary with colored water in the core, it is possible to make ice decorations in various colors and apply them successfully.  Click here for information about color for ice lanterns.

Displaying outdoors -- ideas for bases

Bases lift your icy creations up to viewing level, keep them from being buried in new snow, and enhance their appearance.  You might want to nestle some luminaries in the hollows, but don't overlook the possibility of putting them on a pedestal.

Ideas for ice lantern bases are here.

Other ice decorations

There aren't many daytime hours in
the middle of the winter, but you
can fill them with ice objects
other than just luminaries.
For daytime displays, ice scenes can be set up to catch the sun, without needing to be designed to hold a candle.  For these, I often make an "ice window" using just a couple of inches of water in the Arctic Ice Lantern mold, which avoids the problem of that mold cracking if it is left too long to freeze.  Here is a sampling of ice window scenes.

An "ice window" frame is decorated
with ice snowflakes and attached to
a base with several ice trees.


Other ice scenes such as a fishbowl with fish, or an ice-fishing scene, are found here


Lighting

If you use candles in a few ice lanterns on special occasions, you'll probably just buy them.  If you are lining a sidewalk with ice lanterns and lighting them whenever the weather is cold enough, you might want to pour your own and recycle your candle stubs.  Here are some suggestions.

LED lighting can give you a wider choice of colors, keep your ice lanterns from melting when lit, and allow you to light ice objects that don't have chimneys or a fresh air supply.  Read about some ideas for lighting here.

Problems, disasters, and catastrophes -- and the inevitable

Really, chill out.  There's not that much that can go wrong, in the global scheme of things, because -- you know -- they're all going to melt in a couple weeks anyway, and spring will come

They all fall apart and melt eventually
.

    1. Wintercraft offers a very nice warm, waterproof glove on their website, and I have a pair of those. They work great. However, I usually just work bare-handed for short amounts of time, sometimes warming my fingers with a jug of hot water or a towel. Most of what I do is on my front porch, so it's easy to go inside to warm up.

  2. I love the lantern post. I have sheperd's crooks that I place in pots and aroud my porch to hang lanterns on special occasions. I also have a very large pair on my mantel that I light often....it makes me happy! Thanks for sharing.
