As a DIY blogger, I’m always excited to try new products, and Unicorn SPiT Stain and Glaze was an instant favourite. After testing it on a wooden party trough table, I couldn’t wait to see how it worked on glass—and it was even better than I expected! You don’t need artistic skills to create stunning designs; even a child could do it. The best part? Each design is unique, making your project one of a kind. Though I’ve used Unicorn SPiT on other surfaces before, applying it to glass brought a whole new level of creativity to the table.

What is Unicorn SPiT Stain and Glaze?

Unicorn SPiT is a versatile gel stain and glaze that can be used on various surfaces, including wood, metal, fabric, glass, and ceramics. It not only stains wood but also gives a gorgeous glazed finish, adding depth and dimension to your projects. It’s the perfect product for adding vibrant colour and texture to any surface, including glass vases, bowls, and even plastic!

Materials Needed:

• Unicorn SPiT Stain and Glaze or the new Shimmer range
• Plain glass vases or wine glasses
• Small plastic bottles (for diluting Unicorn SPiT)
• Water spray bottle
• Paper towels
• Metallic gold spray paint
• Clear polyurethane for protection (optional)
• Masking tape

Preparing the Glass for Your Design

Start by choosing glass items with smooth surfaces. I found old wine glasses and a vase around the house, but any clear glass will work. Wash the glass thoroughly in the dishwasher or with warm soapy water. Clean glass ensures the Unicorn SPiT adheres properly to the surface. Cover your work surface with plastic or paper towel to protect your surface.

Applying Unicorn SPiT to the Glass

Shake the Unicorn SPiT well before use. Apply a small amount of your chosen colours around the inside rim of the glass. If using black, be cautious—it can easily overpower the other colours. I recommend sticking to just 2 or 3 colours for each project, as too many can blend into one another and diminish the desired effect. Remember, less is more, and a little goes a long way.

The Unicorn SPiT should flow slowly down the glass. If it doesn’t move freely, it’s too thick and needs diluting. I prefer not to dilute the main bottle, as it can change the consistency. Instead, I use small plastic bottles for dilution. A plastic syringe works well for applying the stain to awkward shapes. To dilute, add a small amount of water—about a tablespoon at a time—and stir until the desired consistency is achieved.

As the Unicorn SPiT moves down the glass, you can tilt it on its side to guide the colours in a different direction.

A simple trick is to balance the vase on a roll of tape. After a few minutes, move the vase again to help the colours spread. Continue until the entire glass is covered. You can tilt or rotate the glass to help the colours move. Be patient—this part creates the unique marbled effect.

How to create the veins in the colours

Once the glass is fully covered with Unicorn SPiT, it’s time to create the veins. For this step, you’ll need a spray bottle set to a fine mist. Lightly mist the inside of the vase three times. As the Unicorn SPiT runs down the glass and mixes with the water, veins will begin to form. If you don’t see any veins, your Unicorn SPiT may be too thick—simply spray another fine mist of water to reactivate the stain.

Next, remove the excess Unicorn SPiT. Lay down some paper towels, then carefully turn the vase upside down. The excess will slowly run out. You can scoop up the runoff and reuse it on another project if you prefer not to waste it. Once all the excess has drained, return the vase to its upright position and leave it in the sun to dry. On a hot day, this should take around 30 minutes.

Add the metallic gold spray paint

I got so caught up in the project that I forgot to take a photo of the vase before I sprayed it. However, the image below shows what it will look like once the Unicorn SPiT is dry, which will give it a powdery finish.

Adding the Gold Spray Paint

Before applying the gold metallic spray paint inside the vase, use masking tape around the rim to prevent any overspray on the glass. There’s no secret to applying the spray—just ensure the entire inside is evenly coated. The gold paint will settle into the veins, enhancing the effect and giving your vase a stunning finish. Let the vase sit until the paint is fully dry.

To protect the interior, you can apply two coats of clear polyurethane. In the image below, you’ll notice some overspray on the top of the vase, which I cleaned off with paint thinner.

For a touch of mood lighting at your next dinner party, simply add some battery-operated lights inside the vases. This easy addition will create a beautiful, glowing effect that enhances the overall ambiance.

Here is the vase with battery-operated lights inside. These vases are purely decorative and are only suitable for battery-operated lights. They are not designed for use with tea light candles or any flame sources.

I used Unicorn SPiT to add vibrant colour to this wooden wall hanging, giving it a beautiful and unique finish.

The colour on this wooden house number was created using just one shade of Unicorn SPiT and a burning technique called Shou Sugi Ban, which adds depth and a unique, textured finish. You can find all my unicorn spit projects HERE if you are looking for inspiration.
