Epoxy resin and colourants

Need help with the above. First attempt. Can anybody help me where to get a selection of colourants and best prices for the resin. Also what is best to use for the colourants, i.e. dyes versus powders??? For use in river tables, etc. Thanks

My old work used to get pigment paste from Solid Solutions, turns out they actually have a dedicated river resin https://www.solidsolutions.com.au/pr...n-water-epoxy/

Seems their site is a bit screwy at the moment so i's kinda hard to navigate :/

Thanks, I will check it out tomorrow:)
