For Modelling clay I contacted following companies:
- Jovi
- Chavant
- Clay & Paint Factory (the Cernit people), 2nd try
- Beck Plastilin
- Morocolor (-> Primo)
- Flair Leisure Products PLC (Plasticine)
I did not contact G.Lalo- J.Herbin for Plastiline, because they already stated previously that they are not interested in vegan art supplies at the moment.
There are about +six more modelling clay companies on my list that I will contact soon.
