Review on Versatile Silicone Mold Making Kit for Art Projects and DIY – Includes Liquid Rubber Compound – Ideal for Copies, Home or Industrial Use (2.5 Lbs. - 40 oz.) by Michelle Miller

I usually use another brand. but I decided to try this silicone brand. I use it to make real crystal molds and then fill them with resin. The packaging is very practical. without smell. parts a and b are not that viscous, so they pour very well. easy to mix everything is ready within 3 minutes. and you will see it because there are different colors, one is white and the other is purple. no bubbles. therefore, no vacuum chamber is needed. after watering wait 6 hours. I left it overnight and the next day I removed it. it was very easy. and then I cast the resin and after it had hardened there was no problem getting the resin out of the mold and it gathered all the detail and brilliance of the original crystal. so overall it was a success. I will share but so far everything has been going so smoothly. here is the update. They said the working time is 30 minutes and the curing time is 6 hours. for me the working time is 10 minutes and the curing time is 3 hours. I live in a place where the temperature in my house is 25°C. Maybe that's why it hardens so quickly. Everything else is alright. I use it for resin and it works great.
