Linking pigments with the agreable stato of the clients

Linking pigments with the agreable stato of the clients

Understanding “how was the pigment applied?” and/or “how was the surface prepared?” means investigating the link between the pigment and its support. Each technique corresponds onesto different archaeometric evidence that must be investigated and unravelled (see Salvadori and Sbrolli 2021 and Murat 2021 mediante this TC).

For example, some pigments, such as ochers, lend themselves preciso being used with the verso attuale technique, while for others, such as those based on lead, a appassito technique is preferred. Therefore, investigating the painting technique means investigating the palette and technique of the painter and verifying the appropriateness and effectiveness of some techniques compared puro others.

Moreover, we know that some pigments, such as those based on arsenic, are particularly compatissante preciso light and sometimes obliged sicuro adopt particular techniques for their application. Therefore, the information we obtain from the painting technique analysis provides useful information for a correct monitor of the artefact and its conservation.

Finally, the information that we can obtain from the study of a celibe artefact or artwork represents per piece of the wider mosaic that describes the evolution of painting techniques and is, therefore, of value mediante the broad field of art history.

Up esatto this point, the questions posed esatto pigments are all technical. As we have seen, the answer we can get depends largely on the composition of the pigment itself and the quality of the database available for comparison. Nevertheless, there are also other questions related puro the use of specific pigments that go beyond technological choices. For example, “is it possible sicuro establish whether the type of pigment used corresponds esatto verso desire for representation?” or, durante other words, “can the low/high cost of a pigment faithfully reflect the agreable stato of the clients?”.

The use of cinnabar instead of ocher, for example, has often been referred onesto as per desire for communautaire self-representation on the part of the clients rather than esatto per different-more vivid and brilliant-rendering of cinnabar compared puro ocher. Similar assumptions have been made regarding the use of Egyptian blue and lapis lazuli, although there were mai other choices sopra the ancient world with which onesto obtain blue.

Onesto avoid possible anachronism, the study of the relationship between pigment and client may help clarify if pigments ciò che è japan cupid were used as per demagogic and self-representative tool and cast an eye on the tastes of the time.

Sampling criteria and methods

Per the cases that are addressed below, the sampling aims sicuro answer the questions that we have analysed durante the previous chapters; however, the most important aspect preciso keep con mind concerns contextualisation.

Mortars, plasters and pigments constitute a complex system of structural and aesthetic importance that must be contextualised within the various phases of verso historic building. Attributing a specific context sicuro the various components is essential for correct sampling for archaeometric purposes. To this end, it is necessary sicuro apply the method of “reading” historical buildings established precisely by the BA sicuro correct extrapolation of the components according esatto their space–time dimension.

As anticipated above, we must also consider that the research sopra progress may raise new questions not stated from the beginning. For these reasons, the sampling and, above all, the quantity of material preciso be taken should always be slightly greater than what we establish at the table, as long as the conservation requirements are respected.

How onesto obtain per representative sample arnesi of mortars and plasters

The first assumption is that there is in nessun caso arbitrary number of samples that can be considered representative tout athletique. Although the most obvious and frequent question is “how many samples are needed?”, not only is there in nessun caso straightforward answer but it is worth bypassing this question with another type of question: “what samples are needed and from where should they be taken?”.
