Bought this glasscast 3 for a project about 8 months ago and worked very well.
Mixed up a litre today by weight 100/50 as per instructions for 10 minutes. Steam started coming off and went totally solid a couple of minutes later....... really not happy !!!!!

I see and I get what you’re saying however I followed the instructions correctly.
There should be limitations written on the instructions as to what not to do then if this is the case.
As far as I’m concerned, I followed the mixing instructions correctly but I appreciate what you’re saying so thank you 👍
