TAPERED EDGE ON CRIN
- Slide the Crin into the plastic part of the 'tool'.
- Pull it a short way up the Crin, make sure all 'threads' are laying flat
- Slide the 'tool' back down, leaving approx 3mm protruding
- Burn off the excess Crin in the flame of a candle
- After 3 seconds remove the 'tool', pulling it away for the Crin to keep it clean.
- Tap the end of the melted Crin gently on a glass or ceramic tile. Just enough to get a flat end, without it spreading
