Very helpful Thank you.

[@JuliaMcNeillCrafts]

Great technique I have only ever used paper clay in these moulds x

Well you faired much better than I did....I used the same recipe as you but 90% of mine broke getting them out of the molds. I was beyond frustrated as I tried so hard to be gentle but they fell apart so easily.......which is why I was seeking out vids like yours and I couldn’t believe how well you did..kudos!

[@CurioByBSpokeDesigns]

harmony331000 did you add PVA glue? I used a Anita's Tacky Glue, I wonder if that made a difference?

[@harmony331000]

Curio By B-Spoke Designs ...hmmm, I’m going to try a different brand of glue....also, in watching you again I realize my water wasn’t cold enough ...and I didn’t use talc😞definitely my bad!! Thank you for the great advice and for sharing. I’m going to try again today!

[@harmony331000]

Curio By B-Spoke Designs oh, lol, and I used Elmer’s glue all for the glue addition...is that stuff ok?

[@CurioByBSpokeDesigns]

Elmers should be fine

[@MegaSneetch]

old comment but you can try dental stone/flow stone/dental plaster as it's much stronger than plaster of paris.

[@lenaberesneva]

Thank you for you video, but how do you finish them? Do you use some stone polish?

[@CurioByBSpokeDesigns]

I tend to paint them with acrylic paints.

[@CMonstersmom]

Do you paint these with Gesso prior adding color Acrylics or applying them to your art piece?

[@CurioByBSpokeDesigns]

yes, usually but as this is plaster, it's not really necessary.

[@shannongabor750]

Do you think you could use the Plaster of Paris in a larger silicone mold - size 8" x 3"?

[@CurioByBSpokeDesigns]

Yes, I can't see why there would be any problem

[@shannongabor750]

@@CurioByBSpokeDesignsThanks I'll give it a shot because t's cheaper than resin.

[@christianurbina1465]

how do you finish these pieces? do you add a sealant?

[@CurioByBSpokeDesigns]

I usually use them in mixed media pieces and so I paint them

[@marikiemarie7622]

Yes. I've never heard someone putting in dry first .

[@Zyswest]

what is the glitter blower called and where could one purchase one?

[@CurioByBSpokeDesigns]

It's just called a glitter blower or glitter pump and I got it from a local craft shop. They are also used in cake decorating.

[@lzrd8460]

Using acrylic caulking that has some silicon in it is much easier and not expensive. Using plaster of Paris to make objects looks too frail.

[@lzrd8460]

Have you tried using paper clay or air dry clay?

[@CurioByBSpokeDesigns]

I have but I find air dry clay is prone to cracking.

[@lilithmorgan4632]

Can i make a key chain with please?

[@CurioByBSpokeDesigns]

I would use polymer clay or normal resin. This is too brittle.

[@lilithmorgan4632]

@@CurioByBSpokeDesigns thank you

[@kelly4328]

What ratio of glue would you say to use?

[@lzrd8460]

He used 1/2 Tbsp of glue to 2 Tbsp of plaster of Paris.

[@cilonen]
