Made two bowls that I felt were acceptable for resale.Thin walls(reinforced with mesh),they polished easily and look great.Produced them about 4 weeks ago.
Got a show next Saturday/Sunday.Got lots of product,including these bowls and a ball as well(thanks,Laura!).I was going to do a basic Japanese style fountain with an industrial twist(instead of bamboo,go copper instead).
A week to go and,cracks started to appear on the bowls!!This kills the sale idea(I'll fake it for the show and "demo" the bowls instead)and brings me to my point(and mistake):I was using 100%admix here,no water.I was NOT careful in curing because I'd used this mix before on thicker objects with no cracking at all.A very big mistake.
When it comes to curing,EVERYTHING of mine is going to be cured.With this very thin walled stuff(we're talking 1/4 inch,folks!)it needs a full on cure,no variation.
So,to paraphrase an old Xmas carole"Let it cure!Let it cure!Let it cure!"
Cheers from a frustrated here!!
