https://www.wetcanvas.com/forums/showthread.php?t=1431363Ahh Delofasht great minds think alike that is the ones been looking at funnily enough polychromos have emailed company to double check they say they have no wax etc jus oil and lead. Yes ditto I try to keep as simple as possible because the more things you are adding and changing the more suseptible to incompatibility etc as even when you ask commpanys egzactly what is in there product they don’t always tell you everything and even when you do apply the proper rules to using the right thigs together things can still go wrong there are even subtletys within that
Polychromos were on sale on amazon last I checked. They used to be 300+ now theyre like 160. I don’t think there is any issue with it. There may actually be some wax in them. I havent had any trouble and I use them frequently. I don’t layer them though. Just a light outline. The binder probably isn’t strong enough to hold down a thick layer of paint. That would be kinda like paiting over pastels.
Im using luminance for my next color pencil piece though. I’ve see some work with them and they are out of this world vibrant. Polychromos take much more layering to get a nice saturation. IDK new toys I’m excited about.

More on the polychromos pencil thing.. I used them on Winsor and Newton oil ground and it doesn’t dissolve when you paint a layer over. It’s almost like a dried layer of oil paint. It stays put. Which can be good or bad depending on your needs. You could probably do a underlayer and glaze over it like dcam with no problem. I don’t think you would even need to seal it. It all depends though…

Fixing an under drawing prevents the drawing from mixing with your paints, but not from striking through as the paint becomes more transparent.
My understanding is that the material that makes up the dark line or shape is irrelevant when it comes to strike through (is this the right term to describe underlying layers appearing as top layers become more transparent?) showing up later. The cause is the increased transparency of the layers of paint that allow the darker line or shape to show through. It has nothing to do with the fact that the line was made with graphite or any other material, when it comes to this type of strike through that happens over an extended period of time.
Charcoal when NOT fixed tends to dissipate as you paint over it, obliterating strong dark lines. It also tends to give less color contamination than graphite. If the charcoal lines are fixed before paint is applied, then the possibility of strike though years later, would be the same as lines made with a graphite pencil or any other tool – if they were of the same strength and contrast against the underlying surface.
That last part about charcoal was surprising, but as I think about it, it makes sense if the real issue with strike-thru has to do with the way the paint covering the drawing material experiences increasing transparency over time. And it explains why it’s much less likely to happen with charcoal if it dissipates into the paint. So, the very characteristic that leads me to like The General’s Charcoal pencils – that they’re firmer than regular charcoal and make a more distinct and less smeary line – is likely to lead to strike-through!
BTW, Delo, and others who mentioned the OT issue, I don’t really think the issue of strike through can be separated out from the OP’s question. Since there are known problems with graphite strike-through, that’s something to be considered along with any questions about the mixing of the material with the oil paint, and it seemed the right thing to bring it up.

Annie yes as you say it’s not worth having kittens over..however you wouldn’t want a realy obvious grid on there
Dcam..well it’s a bit of bothe ..using the graphite for an underpainting drawing..which yes argueably some like to put under a layer and redefine a little bit after on the next layer..some like it on there and paint directly over..which is what i was wondering about as charcoal you see is used this way and painted directly over as it will blend wash away etc …and i had read some people did this with graphit/lead pencil albeit a soft one saying it mixed in with the oil paint and there is a coloured lead pencil out there soo..if this clarifies..aparantly the polychromos dont have wax but am double check with company whats in there..yes I can’t abide stretched canvas iether much prefer a sollid wood board but that’s what comes with growing up with a woodworking craftesman lol boy do i know my wood lol
Dcam absoloutly heavenly work there of yours
