Is poppyseed a drying or retardant oil? My Geneva paints are running low and started changing their properties a bit, e.g. higher viscosity near the end of the tube. Adding a bit of medium is a good fix, but when I switched from linseed to poppyseed oil (just out of curiosity, plus it’s said to have less yellowing potential) the painting was dry within 24h like never before. Rookie mistake?
