How Do You Make Homemade Perlite

Mix equal parts of dry cement, sphagnum peat moss and perlite in a bucket or other container. Measure each ingredient by volume instead of by weight, so if you measure with a dry scoop, use an equal number of scoops of each ingredient.

How do you make perlite at home?

Combine 1 part perlite and 1 part peat moss with 1 part compost, pasteurized garden soil — soil you have baked at 250 F for half an hour — or purchased bagged soil, usually labeled “Garden Soil,” from a nursery to create a potting mix suitable for containers indoors or out.

What ingredients are in perlite?

  • 70-75% silicon dioxide.
  • Aluminum oxide.
  • Sodium oxide.
  • Potassium oxide.
  • Iron oxide.
  • Magnesium oxide.
  • Calcium oxide.
  • 3-5% Water.
