Crownmade Geode Slice Silicone Molds for Resin and Epoxy Resin Casting 4 Pieces

Molds leave lumpy marks on resin.

Amazing quality & amazing price! I've never had a single issue with these molds. I do a tun of floral preservation coasters and these are by far the best quality coaster molds I have ever used. They are thick & sturdy and although some reviews say they had an issue with resin sticking to the mold after using heat, I have never had an issue and I use a heat gun every time. I hope they come back in stock soon & I am looking forward to purchasing more molds from this company!

Great shape and size

Ich habe schon viele Silikon Molds ausprobiert, aber von dieser war ich sogar noch überrascht. Was sofort auffiel war die super Verarbeitung und Qualität des Silikons selbst.+ Silikon ist blasenfrei+ Festigkeit und trotzdem flexibel+ löst sich gut ab und ist gut zu reinigen+ schöne Geoden Form+ super netter Kundenservice

I used these to make resin coasters

The first 2 sets of molds I ordered had a thick lip around the top. While the second 2 sets didn't. But all the molds where thick and good quality and deserve 5 stars. The first and second round of coasters I'm made for my niece's wedding came out of the molds easily with no problems. But then I noticed that there were a lot of bubbles in the clear layer of resin. So for the third round I removed the bubbles with my butane torch. I think I may have went too close to the molds because only 1 out of 16 came out of the molds without sticking and tearing the molds. 😥I'm afraid to continue using the molds for the rest of this project (I'm making 96!), so I ordered 4 more sets. I will TRY to be more careful about removing the bubbles and stay away from the sides.
