Definitions
- the present invention relates to the field of restoration. Specifically, it refers to the field of bone material restoration.
- bone remains are the materials that are most frequently found, after ceramics, in a field.
- those skeletal remains can be distinguished both human and wildlife remains, as well as those manufactured with the latter, utilitarian objects such as instruments, utensils and accessories or objects of a decorative nature (usually with ivories), symbolic, religious, or belonging to rituals.
- the purpose is to obtain a stucco or filler suitable for water-sensitive works, as an alternative to those used so far for the volumetric reintegration of lagoons in archaeological bone materials. Since the problem of volumetric reintegration is not only limited to the decision to proceed with its reconstruction, but also to the choice of material, the filler putty must comply with most of the requirements or properties required of a good stucco, as well as the suitability with the constituent material of the piece, so that it does not cause subsequent pathologies on the work.
- Volumetric reintegration is rare, and can be considered as an objective treatment, and hides cross-sectional information from the original specimen (White, T.D. and Folkens, P., The Human Bone Manual 18 (2005), 338). However, it is carried out when the pieces present structural stability problems, for conservation reasons, in order to return the mechanical resistance, for pedagogical criteria and for the possibility of their subsequent manipulation if they are intended for study or presented in exhibitions.
- plaster as stucco, being a rigid material, presents a different behavior in the face of aging, causing stress to the piece that is translated into cracks, detachments and separations in the area of contact with the fracture.
- the wax stucco (recipe 176) does not provide moisture to the piece, but on the contrary it must be taken into account that it is highly sensitive to heat, also presenting adhesion problems in large lagoons. Additionally, as shown in the image represented in Figure 1 (FIG. 1), it presents problems similar to the stucco of plaster (fissures, detachments ).
- object of this invention to present a new stucco material for the conservation and restoration of bone materials. Specifically, it is the object of the invention to present a stucco or putty with good flexibility characteristics to adapt to the possible dimensional variations of the piece, and which also remains stable to long-term environmental fluctuations.
- this new stucco is characterized by presenting optimum flexibility characteristics to adapt to the possible dimensional variations of the piece on which it is applied, in addition to remaining stable to long-term environmental fluctuations.
- the filler or stucco of the present invention is characterized in that it comprises, in percentage by weight:
- binder (a) between 15% and 30%, more preferably between 20% and 25%, of at least one binder, said binder being Paraloid® B-72 (70% ethyl methacrylate, 30% methyl methacrylate) dissolved in acetone (CH 3 COCH 3 ), preferably 20%;
- the plaster is selected from dental stone plaster (type III) and ceramic plaster, or a combination of the above, preferably 50%.
- the type III dental stone plaster may consist of dental Hebodur® (calcium sulfate CaSC .23 ⁇ 40), light cream colored.
- the ceramic plaster may preferably consist of a white plaster called Alamo 70® (calcium sulfate hemihydrate).
- the selected glass microspheres are characterized by preferably having a composition of S1O 2 (72.5%); CaO (9.8%); A1 2 0 (0.4%); NaO (13.7%); MgO (3.3%); FeO / Fe 2 0 3 (0.2%) and K 2 0 (0.1%).
- the combination of fillers in the stucco may comprise, by weight percentage, 45-50% Hebodur® and 50-55% glass microspheres.
- Paraloid B72® as a binding material is justified by being a colorless and transparent acrylic resin, with little tendency to yellow over time and for being very stable against most environmental agents. In addition, it has resistance to water, alcohol, alkalis and acids and weak reactivity with pigments. It also has good results in the use of other phases of restoration on bone material, both as a consolidant or as an adhesive.
- Figure 1 shows the image of a camel skull from the collection of the Archaeological Museum of Lliria (Valencia), as well as a detail of cracks, fissures and area of stucco detachment;
- Figure 2 shows a set of experimental stucco and traditional stucco specimens (size 3.0x3.0x0.5 cm);
- Figure 3 shows the results of the AH-M-1 work / test test of the experimental stucco and traditional stucco test specimens
- Figure 4 shows a representation of the moisture content housed in the porous system of the specimens
- the materials selected to prepare the stucco stucco of the invention under test have been: Paraloid® B-72, Alamo 70®, Herbodur®, glass microspheres and marble dust.
- Thermo-hygrometric accelerated artificial aging.
- FIG. 3 the set of worked specimens can be seen, as well as the result of the work test / Test AH-M-1.
- the putty AH-50% manifests a greater intercommunicated porous volume, so the demonstrated absorption capacity entails the contribution of moisture to the original. These results are reinforced with the surface tension test.
- Example 2 Tests of accelerated artificial aging.
- the color difference parameter (AE * ab) has been used to evaluate the results.
- the calculation of the results has been based on the data provided by Melgosa, which qualifies as a "supraumbral" color difference to that around 1.75 CIELAB units.
- the instrumentation used in artificial acceleration accelerated by irradiation with UV light has been a QUV-Basic accelerated aging chamber with a UVB-313EL UV lamp.
- the specimens have been exposed to a cycle of 297 hours under continuous ultraviolet radiation, to determine the resistance of the experimental putties to the artificial light of ultraviolet lamps. After the test it can be seen that according to the inert filler composition, the AH-M group responds better to aging than the AH-P, except AH-M-1, as can be seen in Table 3.
- thermohygrometric accelerated artificial poisoning has been a Dycomtal DI-100 climatic chamber with a temperature range between - 25 ° C and -150 ° C and a range of RH between 15%.
- the cooling and heating gradients were 1 and 2 ° C / minute respectively.
- Cycle 1 6 ° C-30% RH for 24 hours for cold-dry weather
- Cycle 2 40 ° C-80% RH for a hot and humid climate.
- the color difference parameter (AE * ab) has been used to evaluate the results.
- thermohygrometric artificial poisoning AH-P-2, AH-P-3 and AH-M-4 we can determine that they are more stable to accelerated thermohygrometric artificial poisoning AH-P-2, AH-P-3 and AH-M-4, presenting a smaller increase in AE * ab compared to traditional stucco AH - 50%, included within the parameters around 1.75.
- the specimens as in the first aging by ultraviolet irradiation, have been exposed to a cycle of 297 hours under continuous ultraviolet radiation.
- the specimens have been selected for this second phase of aging: AM-8, AP-2, A-P20%, AH-M-2, AH-P-2, AH-P20 %, H- M-2, AH-P-2, H-P20%, from the group of acrylic acrylic putties. From the traditional putties AH-50% and Alamo® 70 have been selected.
- AH-50% With respect to the traditional putty AH-50%, in general it remains stable to both poisoning tests. AH-M-2 remains more stable to ultraviolet radiation than AH-50%. As can be seen in Table 3, it has a lower value than AE * ab; while AH-M-4, AH-P-2 and AH-P-3 respond better to humidity and temperature variations.
- the degree of pasture of the putty has defined how to distribute it in the mold, by pouring or using the spatula. The ease of use has varied according to the subjects chosen.
- a color chart has been obtained by conferring the loading material its own color.
- the colors used for the fillers used were white, gray and beige, and another series of pigments can be used in particular embodiments.
