Ladies and Gents, I tried melting some OP's for making some more greens out of that garish green they give you. My experiement started with senn. #218 and #30. What I was lookinf dor was a very daRK green gray. It worked pretty well. Then I had alot of the student grade Van Gogh offered by Dick Blick, Their greens are really garish, to my surprise, I could not get them to mix after melting. All the tinie amount of oil that was left in the mixture, maybe 5 percent oil was poor quality, my guess, alot of wax.
Anyway what I ended up with was a crayon! all the oil would not incorporate back into the mixture. It was a mess. Learned you cannot totally melt them down. I don't buy Van Gogh but my daughters had purchased a whole bunch from a closeout at their local art store. Well now they are in the trash bucket.
The senniliers melted great tho and blended very well. Just in case anyone wanted to know. Andi P.S. my husband was worried that I was cooking some horrible dish for supper, from the smell, I think he was totally relieved it was not his supper.:wave:

Andi, thanks for posting this information. It bears out what we've been saying about student-grade OPs. Glad to hear the Senns worked well for you - a good dark green-gray is certainly a gain. I've been meaning to try my experiment with combining some Senn. transparent OP and powdered pigment. You've given me a push to get going with it. Funny to hear about your husband. :lol: Jane.

Thanks for replying, my poor husband never knows what to expect from a creative mind, he stands back before jumping in!
It was interesting, no wonder poeple do not like student grad ops you might as well buy crayons. No wonder they quit after first attempt. I will be wating for your experiment, geat idea. Andi:thumbsup:

I have used nothing but student grade oil pastels up until now, and have had nothing but good results from them. I also make my own colors by melting and mixing. I have ordered six samples of Sennelier's to try them out, they may be to soft for my liking though, I'm so used to hard op.

Wildart12, I'm glad to hear that you are able to produce good work with your student-grade OPs. You are more the exception than the rule. The problem I frequently encounter is that people try student-grade OPs, find they cannot get them to blend, and give up on OPs entirely. By asking people to try professional-grade OPs in the first place, we hope to avoid the discouragement that so often occurs. Jane

I'm glad to hear that at least some of you melting experiment went well, Andrea. And I've also wished for a while now that somebody around here would start their own little business making those colors that are so needed, but that none of the mfgs. produce. I'm thinking of really light lights, and dark darks, and, (although Sennelier does produce a few excellent grays) grayed colors.

:hint, hint: :evil:

Annie, the problem I've had is with quality control. It's fine for my purposes (when it works), but I wouldn't want to try selling any of my experiments. I couldn't guarantee the outcome! Why don't you give it a try yourself? Jane

Annie...Why don't you give it a try yourself?

Well, the reason I ask is because I know myself well enough to know I won't try it myself :lol: ...I prefer to be painting. I guess that may be the case for others as well. :) But it doesn't hurt to ask!

Interesting! I've melted Holbeins and CDs with good results. I have a handful of the student-grade Holbeins, so now I want to try them and see what happens.

Wendy, let us know the result - I'm very interested to know what happens. I may try melting some of my Cray Pas Specialists, as I don't really like them that much.

Yesterday, I made an OP from part of a large (Grande) Sennelier Transparent Medium (No. 221), melted, and then mixed with powdered pigment 'ground' in odourless mineral spirits. It worked quite well. It's quite soft and buttery 24hrs. later. I will report on it further in the Making OPs thread. Jane

Jane: That is good news, and sounds like just what I've been looking for. How much are you going to charge for them? :evil:

:lol: Here I am, slaving over a hot griddle, trying to find a way to make it easy for you to make your own, and you still won't do it. The thing is, only you can know exactly what it is that you want. And it really is trial and error. The colour seemed to have darkened after I added the medium, when I thought it would lighten :( So, I think you're going to have to try it yourself. :D Jane

I'd be happy to send you detailed specifications and a color swatch. :D

Me too.....:lol: I really admire all of you who are trying to make some of your own colors. One of these days...:rolleyes:
Wildart, you might try Caran D'ache as that is a harder OP, but still a professional one.
