Hard Cup

done2
5 oz hard cups with shot glasses added for Valentine’s Day

Hard cup sparkleballs require a bit more effort. They take 3 days to make, so glue can set. The cups crack easily, and if you drop a hard cup sparkleball, it’s a disaster.   But hard cups are sparklier, and they come in fun colors. Instructions will work for 5 oz cups and Party Essentials  9 oz.  For 9 oz Chinet brand cups the formula is slightly different. (see below)

 


 

Formulas:
5oz   14-11-6-1 / 64
9oz  Party Essentials 14-11-6-1  / 64
9oz  Chinet 14-11-6-1 + middle row of 14 / 78

Hard cup sparkleballs by Carl Boro, who taught me his technique. Carl prefers clear silicon caulk instead of hot glue. The caulk takes several days to set.  He also uses a  |14-11-6-1 + 14 in the middle|  formula with Chinet cups.
