Glace icing, also known as glaze or poured icing, is a popular choice among bakers and cake decorators due to its smooth, glossy finish and ease of use. However, one of the most common questions asked about glace icing is how long it takes to dry. In this article, we will delve into the world of glace icing and explore the factors that affect its drying time, as well as provide tips and tricks for achieving the perfect finish.
Understanding Glace Icing
Before we dive into the drying time of glace icing, it’s essential to understand what it is and how it’s made. Glace icing is a type of icing that is made from powdered sugar and a liquid, such as milk, water, or fruit juice. The mixture is heated to a specific temperature, usually around 100°F to 110°F (38°C to 43°C), to create a smooth, syrupy consistency.
The Science Behind Glace Icing
Glace icing is a supersaturated solution, meaning that it contains more sugar than it can hold at room temperature. When the icing is heated, the sugar dissolves, creating a smooth, consistent mixture. As the icing cools, the sugar begins to crystallize, forming a hard, glossy finish.
Factors Affecting Drying Time
The drying time of glace icing can vary depending on several factors, including:
Temperature and Humidity
Temperature and humidity play a significant role in the drying time of glace icing. In warm, humid environments, the icing will take longer to dry, while in cool, dry environments, it will dry faster.
Temperature:
- Warm temperatures (above 75°F/24°C): 30 minutes to 1 hour to dry
- Room temperature (around 70°F/21°C): 1-2 hours to dry
- Cool temperatures (below 65°F/18°C): 2-3 hours to dry
Humidity:
- High humidity (above 60%): 1-2 hours to dry
- Medium humidity (around 50%): 30 minutes to 1 hour to dry
- Low humidity (below 40%): 15-30 minutes to dry
Thickness of the Icing
The thickness of the icing also affects its drying time. Thicker icing takes longer to dry, while thinner icing dries faster.
Thin Icing (less than 1/8 inch/3 mm):
- 15-30 minutes to dry
Medium Icing (1/8 inch to 1/4 inch/3 mm to 6 mm):
- 30 minutes to 1 hour to dry
Thick Icing (more than 1/4 inch/6 mm):
- 1-2 hours to dry
Surface Preparation
The surface preparation of the cake or pastry also affects the drying time of glace icing. A smooth, even surface allows the icing to dry faster, while a rough or porous surface can slow down the drying process.
Tips and Tricks for Achieving the Perfect Finish
To achieve the perfect finish with glace icing, follow these tips and tricks:
Use the Right Consistency
Make sure the icing is at the right consistency before applying it to the cake or pastry. If the icing is too thin, it will be difficult to control, while if it’s too thick, it won’t flow smoothly.
Apply Thin Coats
Apply thin coats of icing, allowing each coat to dry before adding the next. This will help prevent the icing from becoming too thick and difficult to work with.
Use a Turntable
Using a turntable can help you achieve a smooth, even finish. Simply place the cake or pastry on the turntable and spin it slowly as you apply the icing.
Avoid Overmixing
Avoid overmixing the icing, as this can cause it to become too thick and difficult to work with.
Common Mistakes to Avoid
When working with glace icing, there are several common mistakes to avoid:
Applying Too Much Icing
Applying too much icing can cause it to pool at the bottom of the cake or pastry, resulting in a uneven finish.
Not Allowing the Icing to Dry
Not allowing the icing to dry completely can cause it to become sticky or tacky to the touch.
Using the Wrong Type of Sugar
Using the wrong type of sugar can affect the texture and consistency of the icing. Granulated sugar is the best type of sugar to use for glace icing.

What is glace icing and how is it different from other types of icing?
Glace icing is a type of icing that is made from powdered sugar and a small amount of liquid, typically milk or water. It is different from other types of icing, such as buttercream or royal icing, in that it is thinner and more transparent. Glace icing is often used to create a smooth, glossy finish on cakes and pastries, and is particularly well-suited for decorating delicate or intricate designs.
One of the key characteristics of glace icing is its ability to set quickly and form a hard, smooth surface. This makes it ideal for use in a variety of applications, from cake decorating to candy making. However, it also means that glace icing can be more finicky to work with than other types of icing, as it requires a specific consistency and temperature in order to set properly.
How long does glace icing take to dry, and what factors can affect the drying time?
The drying time for glace icing can vary depending on a number of factors, including the consistency of the icing, the temperature and humidity of the environment, and the thickness of the icing layer. In general, glace icing can take anywhere from a few minutes to several hours to dry completely. Thin layers of icing may dry in as little as 10-15 minutes, while thicker layers may take several hours or even overnight to set.
Temperature and humidity are two of the most significant factors that can affect the drying time of glace icing. Warm temperatures and high humidity can slow down the drying process, while cool temperatures and low humidity can speed it up. It’s also worth noting that glace icing can be sensitive to air currents, so it’s best to dry it in a still, draft-free environment whenever possible.
How can I speed up the drying time of glace icing?
There are several ways to speed up the drying time of glace icing, including using a fan to circulate the air, placing the iced item in a cool, dry environment, and using a hair dryer on a low setting to gently warm the icing. It’s also possible to add a small amount of corn syrup or glycerin to the icing, as these ingredients can help to speed up the drying process.
However, it’s worth noting that speeding up the drying time of glace icing can also affect its texture and appearance. For example, using a hair dryer to dry the icing can cause it to become brittle or develop air bubbles. As a result, it’s generally best to allow glace icing to dry naturally, rather than trying to rush the process.
Can I use glace icing in humid environments, and how can I prevent it from becoming too sticky or runny?
Glace icing can be used in humid environments, but it may require some special precautions to prevent it from becoming too sticky or runny. One way to do this is to add a small amount of cornstarch or tapioca flour to the icing, as these ingredients can help to absorb excess moisture and prevent the icing from becoming too thin.
It’s also a good idea to use a higher ratio of powdered sugar to liquid when making glace icing in humid environments, as this can help to create a thicker, more stable icing that is less prone to melting or becoming too sticky. Additionally, it’s best to work in a cool, well-ventilated area, and to avoid exposing the iced item to direct sunlight or heat.
How can I store glace icing, and how long does it last?
Glace icing can be stored in an airtight container in the refrigerator for up to a week. It’s best to store the icing in a cool, dry place, and to keep it away from direct sunlight and heat. Before using stored glace icing, it’s a good idea to give it a good stir and to check its consistency and texture.
If the icing has become too thin or too thick, it can be adjusted by adding a small amount of powdered sugar or liquid. It’s also worth noting that glace icing can be frozen for up to 3 months, although it’s best to use it within a month or two for optimal flavor and texture.
Can I color glace icing, and how do I achieve different shades and hues?
Glace icing can be colored using food-grade dyes or pigments. It’s best to use a high-quality dye or pigment that is specifically designed for use in food products, as these will produce the most vibrant and consistent colors.
To achieve different shades and hues, it’s possible to mix different colors of glace icing together, or to add a small amount of white or black icing to the colored icing. It’s also worth noting that the color of the icing may deepen or become more intense as it dries, so it’s a good idea to test the color of the icing before using it to decorate a cake or pastry.
What are some common mistakes to avoid when working with glace icing?
One of the most common mistakes to avoid when working with glace icing is adding too much liquid to the icing, as this can cause it to become too thin and difficult to work with. It’s also important to avoid over-mixing the icing, as this can cause it to become too stiff and brittle.
Additionally, it’s a good idea to avoid exposing glace icing to direct sunlight or heat, as this can cause it to melt or become discolored. It’s also worth noting that glace icing can be sensitive to air currents, so it’s best to work in a draft-free environment whenever possible.
