Hi, I'm going to ask a newbie question...eventually.

Background: I want to start developing film in caffenol and just took delivery of a Photographer's Formulary bottle of potassium bromide. I expected powder or small crystals - but got large one inch crystals.

Question: What is the easiest and quickest way to efficiently and effectively get the crystals to a powder or very small crystals? The recipe calls for 1 to 2 grams per litre.

Can anyone advise using appliances found in a normal household?
