A quick alternative to the use of Hama pearls:
1. Take a biscuit cutter or an oven proofed bowl
2. Oil the form(s) well
3. Pour pearls in the forms
4. Melt them in the oven in 200C for 5 minutes
5. Let them cool down and remove the form.
As there is plenty of oil on the pearls, I consequently washed them with dish washing detergent in hot water to get the oil away, put a thread trough and made ornaments for a Christmas tree but apparently you can do bowls as well.
No, it didn’t smoke nor smell bad, the plastic pearls were such a short time in the oven. And no, can’t take credit for the idea, there are plenty of similar posts in the Internet which I found out when googling for some alternative ideas to do with the pearls.
