Hello Lydia,

   I am using Sylgard 184 too. But when I deposite a thin layer of aluminum
using evaporation method, the Al layer I got also has some thin cracks. Maybe it
is caused because of the temperature. Can you share the method how you make the
aluminum layer without cracks and acting like a mast? Thank you!

Best regards,

Licca
