5. Ribbed Plaster & Baking Soda Mason Jar
Idea Overview & What It Means
A simple yet elegant makeover for classic mason jars. By combining baking soda with acrylic paint over plaster-coated ridges, you achieve a porous, pottery-like texture ideal for minimalist Scandinavian or Japandi interiors.
Materials Needed
- Standard mason jar
- Plaster of Paris or joint compound
- Baking soda
- Soft white or greige acrylic paint
- Flat head painter’s tape
- Sandpaper
How to Make It
- Apply strips of painter’s tape vertically around the mason jar, leaving equal gaps between strips.
- Spread plaster over the exposed glass gaps to create raised ridges.
- Peel off the tape gently while the plaster is semi-damp to leave clean raised lines.
- Once dry, smooth rough edges gently with sandpaper.
- Mix 1 cup of acrylic paint with 1/2 cup of baking soda until thick and foamy.
- Brush the mixture over the entire jar in smooth, full-length strokes.
- Apply two coats, allowing drying time between coats, then seal.
Tips & Variations
- Combine two subtle colors (e.g., beige ridges on a off-white base) for a nuanced tone-on-tone finish.
- Use comb tools across wet plaster to create micro-grooves along the ribs.
