ISO Method of making Ivory Paper for the Use of Artists. 



ble of receiving, peculiarly adapts it for the reception of the most 

 delicate kind of pencil drawings and outlines. 



An artist of eminence in miniature painting (not a nielVnber of 

 the Society) stated, that he has frequently used the ivory paper, 

 and finds it to be superior to ivory itself in the whiteness of the 

 surface, in the facility with which it receives colour, and in the 

 greater brilliancy of the colours when laid on, owing to the su- 

 perior whiteness of the ground. Colours on ivory are apt to be 

 injured by the transudation of the animal oil, a defect which the 

 ivory paper is free from. 



Some highly respectable dealers in drawing materials stated, 

 that they have had samples of the ivory paper in their possession 

 for a considerable time, and that it does not appear to become 

 yellow or discoloured by keeping. 



The valuable properties of the paper appearing thus to be satis- 

 factorily established, a day was fixed for the candidate to disclose 

 his process, and to prepare a specimen of the paper in presence 

 of the Committee. Accordingly, at the appointed time, Mr. 

 Einsle attended, and exhibited before the committee his method 

 of preparing the paper: he also gave in a written account of the 

 process ; from which, and from the information obtained during 

 the sitting of the committee, the following account has been 

 drawn up: 



Take a quarter of a pound of clean parchment cuttings, and 

 put them into a two-quart pan with nearly as much water as it 

 will hold ; boil the mixture gently for four or five hours, adding 

 water from time to time to supply the place of that driven off 

 by evaporation ; then carefully strain the Hquor from the dregs 

 through a cloth, and when cold it will form a strong jelly, which 

 may be called size (No. I). 



Return the dregs of the preceding process into the pan, fill it 

 up with water, and again boil it as before for four or five hours: 

 then strain off the liquor, and call it size (No. 2). 



Take three sheets of drawing paper (outsides will answer the 

 purpose perfectly well, and being nuich cheaper, are therefore to 

 be preferred), wet them on both sides with a soft sponge dipped 

 in water, and paste them together with the size (No. 2). While 

 they are still wet, lay them on a table, and place upon them a 

 smooth slab of writing slate, of a size somewhat smaller than the 

 paper. Turn up the edf;es of the paper, and paste them on the 

 back of the slate, and then allow the paper to dry gradually. 

 Wet. as before, three more sheets of the same kind of pajA-r, and 

 paste them on the others, one at a time; cut off with a knife 

 what projects beyond the edges of the -slate, and when the whole 

 has become perfectly dry, wrap a small flat piece of slate in coarse 



sand-
