How to Heat a Wine Glass to Paint

by Jeffery Keilholtz

Painting wine glasses is a creative way to personally decorate your glassware. Design your own patterns or stencils to trace and outline complicated designs or brush art onto the glass surface with a free hand. The trick to painting a wine glass is using low-level heat to bake and solidify the paint. Once painted, wash your wine glass by hand to ensure an undamaged design for days and months to come.

Items you will need

  • Tempered wine glass (optional)
  • Paper stencil
  • Scotch tape
  • Acrylic paint
  • Paint brush
  • Cookie sheet
  • Oven mitts
  • Paint varnish
  • Synthetic fiber brush
  • Mild dish soap
  • Dish towel
Step 1

Select a tempered wine glass, if possible, for painting and heat. Tempered glass is designed to withstand extreme temperatures and is up to five times stronger than traditional glass. A standard wine glass will do if you do not have tempered glass.

Step 2

Press a paper stencil against the outside of your wine glass. Lightly secure the stencil into place with scotch tape.

Step 3

Paint the glass with acrylic paint. Remove the stencil and tape. Allow the painted glass to dry for two full days.

Step 4

Preheat your oven to a low level heat between 120 and 150 degrees.

Step 5

Sit the painted wine glass on a cookie sheet. Place the sheet in the oven for 15 minutes.

Step 6

Remove the sheet from the oven with oven mitts. Turn off the oven. Allow the glass one hour to cool.

Step 7

Coat the paint with varnish. Brush the varnish onto the paint with a synthetic fiber brush. Follow any prefabricated varnish instructions. Allow 24 hours for the glass to fully dry.

Step 8

Wash the glass by hand with mild dish soap. Dry the glass by hand before using.

Tips & Warnings

  • Tempered glass is suggested for increased safety, but it is not necessary.
