How to Get Rid of Mould

Finding that your pottery clay has gone mouldy is very common.  Clay needs to be kept moist to stay workable and it contains organic matter.  These are perfect conditions for the growth of mould.  So, what can you do if you open up your bag of clay and it’s growing green and black mould?  Here are a few tips on how to get rid of mould on clay.

Some ways to get rid of mould on clay include adding bleach, hydrogen peroxide, vinegar, Dettol, or Epsom salts to your clay. Alternatively, you can slice the mould off, or wedge it in.      

Some potter’s swear that a little mould on their clay makes it more plastic and easier to use.  For them, getting rid of the mould is not the objective.  They simply wedge it into the clay and start making pots.
