How to Frost a Glass Table Top

What You'll Need
Magnesium sulphate
Paint brush and/or toothbrush
Rubber gloves
Safety glasses

It is a fairly easy process to frost a glass table top. With a few supplies and a little time, you can change a glass table from clear to frost. Keep in mind that you will be using chemicals and proper precautions should be taken whenever working with chemicals. Make sure that there is adequate ventilation, wear safety glasses and avoid spilling any on your skin.

Step 1 - Preparation

Gather all the supplies that you will need to frost the glass table. The container will be used to mix the chemicals and water together.

Before using the chemical solution, the surface of the table top must be clean of all dirt, dust, grease and fingerprints. If you must touch the glass after it has been cleaned, you should use rubber gloves.

If you don’t plan to frost the entire surface of the glass, you will need to tape off the sections that are not going to be frosted. Use masking tape or stickers to block these areas from the frosting solution.

Step 2 - Preparing the Solution

The magnesium sulphate, dextrin and water should be mixed together in the container. The amounts to mix together are:

  • 6 oz magnesium sulphate
  • 2 oz dextrin
  • 20 oz water

Stir well, the chemicals and water should be thoroughly mixed together to get the best results.

Step 3 - Apply the Solution

Make sure the tape in the area that will not be frosted is pressed down firmly so that the solution can’t get under it.

Working in a well-ventilated area, apply the chemical solution using the paint brush or toothbrush. A paint brush, depending upon the size, will help the solution to be applied over the glass table top quickly and completely. If you are looking for a more intricate or detailed design or working in small areas, the toothbrush may come in handy to apply the solution. You need to apply the solution in a thin and even layer everywhere that you want the glass to be frosted. Avoid breathing in the fumes from the chemical solution.

Step 4 - Finishing Touches

Leave the solution alone to dry on the glass; this usually takes approximately 24 hours. As it dries the magnesium sulphate will leave a very fine crystallization on the table top which leads to the frosted effect.

If you have areas that were sectioned off, you can remove the tape or stickers once the solution and frosting process is completely dry. Remove the tape very carefully.


Take care when working with chemicals. If any of the chemicals or chemical solution splashes on your skin, immediately and thoroughly wash it off with warm running water.

  • Make sure that you use safety glasses.
  • Make sure that you work in a well ventilated area.
  • Use rubber gloves when handling the glass once it has been cleaned.
