Animal collagen (rabbit skin glue, hide glue and gelatin) can cause allergic reactions in some people, although the reaction you may have had could have been caused by inhaling dust particles. This would be case, if you do not have a reaction to the granules.

If your friend has glued the top section correctly, and maybe added some stainless staples, or fine-gauge brass or stainless flat-head screws (countersunk, then the heads filled), there should be no problem at all with longevity.

If you are ardent about a kovcheg, then you're on your own. I have tried everyway I can think to make a jig to cut the kovcheg and I just get frustrated. I just quit and paint a frame.
One way around it is to mill a "top section" with a jigsaw and router or hand tools in a board of appropriate thickness. This open frame shape can then be attached to the flat base board, and the lot then prepared in the usual way for painting.

Are you going to use an acrylic gesso? I would be tempted to seal it first. You could use KILZ which has a shellac base to seal the current gesso and then apply the acrylic gesso. That would help with the orginal gesso asorbing stuff. Nice thing about acrylic is that it comes in a spayer, which you probably won'y want to use. I apply it on my boards with a sponge roller. Makes a nice finish.

Lately, I have been using panels from Dick Blick that are finished for acrylics. They have a 3/4 or 1 inch frame on the back that gives the work some thickness. I use Innerglow panles also but the Blick panels take waterbase paint better and are way less expensive especially the store brand. Drawback: they have a "canvas" texture. I prefer smooth so I do a bit of sanding to knock down the texture,

Lastly, a birch panel plywood sheet can be cut into a bunch of panels, rout the edges with a 45 degree chamfer and apply several coats of acrylic gesso directly with a sponge roller. Great stuff and has a nice traditional weight and feel. If you are ardent about a kovcheg, then you're on your own. I have tried everyway I can think to make a jig to cut the kovcheg and I just get frustrated. I just quit and paint a frame.

Hope that helps

That makes sense. Worse, as of today I've clearly developed a contact allergy to dry ochre pigments. I think God's trying to tell me something about the desirability of heading toward gouache or acrylic (of course you've been doing those for years very successfully, I know).

I'm smack in the middle of an icon of the Nativity and can't proceed unless I wear gloves. Maybe someone with more dexterity than I can paint in nitrile gloves, but I have enough problems without them :-) I can't sand the board down and re-gesso in acrylic because the dust would do me in (even with a dust mask or respirator, it would get onto skin and light me up). Do you think it'd be possible to gesso over the current work (roskrish layer only so far) and simply proceed by starting over atop that?

Sigh. I will miss egg tempera. I like playing in dirt, but it doesn't seem to like me anymore.

The nurse in me says that any protien can have allergy potential. Especially if you are already allergic to furry critters.

Hello;

It's been awhile since I've been on the forum. I have a question...does anyone know whether rabbit skin glue is a known allergen for people who do otherwise have allergies? I bought a new bag of glue, quite fine grain, and as I started working with it, realized that my asthma was tightening up and my sinuses were hurting. I was very careful (I thought) not to let the stuff get airborne, but it was powdery, so I must not have been as careful as I might have been.

I just hoped to find out if anyone else has heard of this.
